The wind changed, we can boat down, and so we’re going! More when we can or when we get back.
We’re in need of a bit of scrap lumber (1x2s and 2x4s), to complete construction of a water screening device. Alas, Barrow no longer has a lumberyard, so it is a real problem when it turns out you need a bit more lumber. If anyone has some excess lumber they would be willing to contribute to the Walakpa salvage effort, please let me know.
Time is flying before the field season. It has been insanely busy trying to get some projects to a point that they can be left for a few weeks while we’re in the field, while at the same time getting set to actually go to the field. We have been ordering things, and waiting for them to get here so we can build things, or pack things or prep meals or… And of course, this being the Arctic, shipping delays abound. However, we have gotten the replacement cover for a Weatherport, all the recalled transit batteries, extra new batteries for the handheld radios, Rite in the Rain paper for field forms, the refurbished iPads, the nice new big First Aid kits, chaining pins, Sharpies (lots of Sharpies) and a bunch of other goodies. I got my new tent stuff sack (the original lasted one trip, and all the duct tape in the world isn’t enough to hold what’s left together if I actually put the tent in it) and my InReach. We are still waiting on the parts for a water screening station, and the dry goods.
The lab looks a mess, because everything is still out from the inventory, and needs to be packed, but some of the things to pack it in are part of the freight. Not optimal, but it will sort itself out.
The freeze and chill food got in, and Kaare will be working with the volunteers to prep a lot of meals to freeze before we head down. That is, once there are enough volunteers here.
The first of the volunteers were to get in Tuesday night, but the plane couldn’t land, so they all wound up heading back to Anchorage, getting in quite late. One got on the early flight today on standby, but the rest are now coming tomorrow morning. I figured maybe 2 nights in Anchorage would be a student budget-buster (having slept under some stairs once when stranded in England for a week on the way home from the field–Laker had raised ticket prices over the summer and I didn’t have a credit card), so I posted on a couple of northern archaeology Facebook groups, and had 5 offers of places to stay from folks in Anchorage within a couple of hours. In the end, folks couldn’t get refunds for the nights they paid for (a downside of online booking, I guess), but if anyone else gets stranded overnight on the way in or out, at least I’ve got a bunch of phone numbers and we should be able to help out. Gotta love Alaskan archaeologists.
Kaare made it to Walakpa, although there is still snow on the beach. There has been a good bit more slumping, but it looks like the overhanging block that was making access so dangerous has fallen, which is a good thing indeed. The plan is to try to take some of the heavy stuff down tomorrow, although that may change depending on if the freight makes it in.
We’ve also got a survey to finish before we go (only got the go-ahead a week ago) and maybe a desktop study as well, depending on their timeframe (just got the go-ahead today). Oh, and a proposal, which was just requested yesterday.
And I need to finish making sense of a bunch of dates which I have calibrated for the WALRUS project. It looks like we have decent ranges for many of the sites based on the caribou dates. There are a couple of sites that are confusing (possible reverse stratigraphy in big mounds) and I haven’t been able to get copies of the field notes or talk to the excavators yet. I’ve calibrated the walrus dates using the marine curve, and it is clear there is not a standard offset from the terrestrial dates. I’m redoing it using the best available local delta R, but I know the one for Barrow is off by several hundred years (if you use it there are a lot of bones from archaeological sites that it indicates will be dying in a couple of centuries!) and there is one site in the walrus study where one pair of dates on associated caribou and walrus is several hundred years farther apart that the other pair. Since walrus move around, some probably more than others, it may not make sense until we figure out where the individuals were feeding.
There are a lot of things that go into a successful project. We’ve been inventorying field gear and project supplies, getting emergency contact forms filled out, finalizing safety protocols and on and on. Kaare Erickson is up from Anchorage for a week or so to help get the gear organized for the Walakpa season, plus another project we’re doing right after that. He’s heading back down next weekend and will do some serious shopping (& screen building) before he comes back up for the field season.
Today we decided to try to get down to Walakpa to see how the site was. Some folks have made it down (including someone in a truck, supposedly. Sean Gunnells, who worked at Walakpa in 2013 came along, and we headed down on ATVs. Alas, yesterday’s snow was not helpful, and the Honda kept bogging down, since it had less ground clearance than the Polarises. We kept having to go up on the tundra, which made for slow riding. We made it to Hollywood, which was probably about nine miles, or a little over halfway there, before we decided that the game wasn’t worth the candle. It would have taken all day, and we had lots of other things to get done. It’s supposed to be warm (in the 40s) for several days, so we hope that a lot of the snow will melt and make for easier traveling.
While we were on the beach, we looked for tracks. We didn’t see any, even near a couple of areas where animals had been butchered. All we saw was an old walrus carcass that must have been dragged up the beach by a bear, but no tracks around it.
However, we had packed lunches, so we went ahead and ate on the beach. A little ring seal popped up in the shore lead and looked at us.
I just put up a new page with the gear list that I’m sending to the folks who are volunteering to help with the archaeological salvage at Walakpa this summer. I thought it might be interesting to people.
If you have experience camping up here and notice anything you think is missing, please drop me a line :-).
UPDATE 5/29/16: I added something to the list, thanks to a good suggestion from Randall O.
So far it has been pretty busy with Tony here. He’d picked out a number of possible samples in advance, and we’ve been finding them. I’ve also been going through the column samples we took last year at Walakpa, and finding contexts that have 2-3 datable samples of both land and marine animal bone. That way, there will be multiple terrestrial dates to give us both a date on the level and information to use to develop correction factors for marine mammal bones. Marine mammal bones tend to give radiocarbon dates that are too old, but sometimes they are the only thing available to date. People generally don’t run dates in those circumstances, but if there were decent correction factors available it would be possible.
We went over to the Inupiat Heritage Center this morning to look at the material they have from Utkiagvik. It looks like there is enough for a whole project there, although the location of the 1981 field notes was unknown for the moment. Some of the staff came out to the lab later and looked at a couple of sewn objects. The mystery one is made out of gut which has been stitched to form a sort of pointed tube, although it is pretty crumpled up. If we get a conservator to visit, it would be great if they were able to rehydrate it a bit and straighten it out.
Tomorrow we are going to be going through boxes of faunal material from Pingusugruk to find suitable samples. There are hundreds of boxes, so Tony is trying to select some contexts to pull, and then I have to ID appropriate bones. I am really hoping that the intern shows up for work.
On the Walakpa front, I’ve been talking with the UIC Science logistics folks, working on how to handle temporary housing for those transiting in and out of the field, and starting to work on travel arrangements.
I have been really busy the last month, trying to finish several reports and papers, plan for the summer, and get ready for a research visit from Tony Krus of SUERC, who was a member of the 2008 Nuvuk field crew before he headed off to grad school. He is now Dr. Krus, and was able to get a grant to come over and work on Bayesian modeling for Barrow area dates, as well as attempting to improve the value for DeltaR (a correction factor used with radiocarbon dates on marine organisms to compensate for the excess older carbon found in the oceans). Between the massive amount of writing I was doing and smashing a finger getting luggage out of the overhead coming back from a trip, I’ve not been blogging.
I hope to catch up with things a bit; there’s been considerable activity on the DONOP/global change threats to cultural and natural heritage front, as well as planning for Walakpa.
I spent most of the day talking about climate change threats to cultural heritage and archaeological resources. I started off at a fairly conventional session about archaeology at various sites in Alaska and the Pacific Northwest, which had a number of interesting papers, many based on analysis of well-preserved faunal remains.
I then went on to the first formal meeting of the newest SAA committee, on Climate Change Strategies and Archaeological Response (CCSAR). Dan Sandweiss, who is the SAA board liaison, as well as being one of the earlier people to call attention to the importance of archaeological sites as archives of paleoenvironmental data, as well as the obvious archaeological data. It seems to be a really great group of people,working in a lot of different places, all of which are having some climate issues. Most of them are interested not only in saving data, but in what that data can tell us about past climates, and about how people adapted to changes in them. As one person said, “We really don’t have much data about the Archaic, the last time people lived sustainably in North America.” This may be a bit of an exaggeration, especially for Alaska, but basically the idea is correct.
After that, I had to go to an appointment in the book room. We will see what comes of that in due time.
Then there was another interesting session on Heritage Tools for Tackling Climate Change. This included a variety of talks on ways people are dealing with the effects of climate change. One had to do with melting ice patches in Glacier National Park, and how the Park Service had dealt with material coming out, in consultation with the local Native American community, as well as studies they were doing so they could be proactive. Another paper included information on the California Cultural Resource Management (CRM) community’s efforts to get public lands on the coast surveyed completely.
There was some discussion about whether the US ban on revealing any site location data helps or hurts. Most other countries will reveal that data, although they may wait until very valuable materials have been properly excavated in some cases. They have found that it decreases looting, if anything. It also helps people avoid inadvertent damage that happens when people don’t know a site is there, and lets them report on changes in site conditions. So instead of a few archaeologists, lots of people can keep an eye on the sites. Here they can’t do that. I suspect, as do many others, that the people who are serious looters already know where the sites are, and have a pretty good idea where to prospect for more. On the other hand, when the US government shut down for a couple of weeks in 2013, looting exploded in the National Parks.
Tomorrow morning the session I organized on Global Change Threats to the Archaeological and Paleoecological Record (not snappy, but lots of buzzwords for search engines) happens.
I am writing this from Disney World, where I have gone to talk about archaeology, particularly global change threats to the archaeological and paleoecological records. The Society for American Archaeology is having its 81st Annual Meeting here, so I am sitting on the 11th floor of a hotel with a view across a lot of fairly low lying land. It might be high enough to survive several meters of sea level rise, but by 20m, the Orlando airport looks like it gets iffy.
I organized a session on, surprise, global change threats to the archaeological and paleoecological records. It should be good, with people presenting on various aspects of the problem in various part of the world (mostly the North), and some possible solutions being tried as well. The session is Saturday morning, and we’ve got Ben Fitzhugh from UW as discussant, as well as a 15 minute discussion slot. I hope we get good attendance, because this is a critical issue for the future of the discipline (and maybe of people in general). Of course, in their infinite wisdom, the schedulers put us directly opposite the session in honor of Lou Giddings, which deals with coastal Alaska. I actually have to read a paper for someone because the primary author couldn’t travel and the second author is giving a paper in the Giddings session at the same time! Meanwhile, I’d already gone to most of the papers I want to see today by 10:30 AM.
Last night I went to the President’s Forum, which was on Climate Change and Archaeology. Dan Sandweiss had organized a nice set of speakers. One of them was Paul Mayewski,who specializes in ice cores and their analysis. He talked about some new software they have, and then he described a new instrument they have which can sample cores in tiny increments, so they can actually see individual storms thousands of years ago in the right type of core! I introduced myself afterwards, and asked if it might work on ice wedges, following up on a suggestion Vlad Romanovsky had made during ASSW. He thought so, and offered to pay to ship a trial wedge sample to his lab so they could try it. Now I just have to get a good sample. Hopefully it works, but either way it will be interesting.
I’ve got a meeting later today (and another on Saturday for those who can’t make today’s) for folks who want to help with 2016 Walakpa Archaeological Salvage (WASP 2016). Today we meet at 5PM at registration, and anyone who is interested is free to come along. Now I have to run off and find the meeting of the newest SAA committee, Climate Change Strategies and Archaeological Resources (CCSAR).
Folks who have been reading this blog are aware that erosion of archaeological sites due to global change effects (warming, sea level rise, etc.) is a huge problem where I live and work. Rapid decay of the exquisitely preserved organic contents of the sites is also a huge problem. But a blog only reaches so many people and actually dealing with the sites and otherwise doing my day job means that I can’t spend endless time on outreach. So when a member of the media is interested, I take the time to talk to them. Sometimes something comes of it, other times not.
Last summer Eli Kintisch, who writes for a number of scientific publications came up and spent a few days in Barrow. He managed to spend a day at Walakpa, although his schedule meant he couldn’t be there for the whole thing. He’s been working on it since, and I think the result is pretty engaging. The resulting article was just published by Hakai Magazine here and simultaneously by the Smithsonian website here. Hakai focuses on coastal issues and just recently published an article on Tom Dawson and SCAPE’s work in Scotland dealing with similar problems (minus the permafrost thawing and sea ice retreat).
It’s a big problem, and one that will take a considerable input of human and financial resources to deal with. We’ve only got a few decades (less in many cases) before all the cultural heritage and paleoenvironmental information in these sites is gone for good.
We went to Glasgow where the 2014 European Archaeology Association was held, by way of Anchorage and Reykjavik. Because flights from Barrow are disrupted fairly frequently, we went down a bit early, and had a chance to visit with our daughter. There was a pretty amazing double rainbow and a nice lenticular cloud.
We flew Icelandair to Reykjavik and then from there to Glasgow. Glasgow was great. The people who live there seem really proud of their city. The cab driver on the way in from the airport was recommending museums, and in particular Christ of Saint John on the Cross by Dali at the Kelvingrove Art Gallery & Musuem. Glasgow was once the second most prosperous city in the UK, and the residents seem to have been very civic-minded. The Kelvingrove was built to house the collections that were donated by prominent Glaswegians, using funds from an international exposition and public subscriptions. It houses a fair bit of Charles Rennie Mackintosh material. We got in a good visit our last day there. Unfortunately, some of the other Mackintosh venues were under renovation.
The meetings were held in various venues at the University, including some very old lecture halls and more modern buildings.
We spent most of our time around the University. There were a number of good restaurants & pubs, particularly along Ashton Lane. We tried a bunch of them. We never made it to this one,which was apparently an isolated inn before Glasgow got so big, near a pond where local curlers used to throw rocks. This is apparently where they went afterwards back then, as curlers are wont to do :-).
Our session (Archaeology and Climate Change) was heavily advertised. Tom Dawson, the organizer, had managed to get leaflets put up all around campus before the session, so it was very well attended. As you can see, there were participants from all over. I talked about the threats to frozen coastal sites from climate change, with an emphasis on the Barrow area. I was able to incorporate images from the storm that had happened the week before. There were some other pretty bad situations, but none that were worse. On the other hand, some people are making strides in dealing with these issues with public help, which is good given the turn-around time for even successful funding applications.
The conference featured a very nice party, spread across two venues, both within a block of our hotel! One was Òran Mór, a converted church which now houses performance space and a bar. The upstairs had been rented for the party. It had obviously been redone from its days as a church. The other was the glass house at the Glasgow Botanic Gardens, just across the way.
The conference banquet was held in the main hall at the Kelvingrove. It was sponsored by Glenmorangie (the distillery near Glasgow) so there were samples of a couple of their special products. After the speeches and dinner, there was a fine band and dancing.
We got up with the goal of getting packed up. It wasn’t clear if the UICS logistics staff would be able to come and get us today, but we decided to finish all the field work, and pack up as much as possible. We got right on the screening, and recording of the edges of the midden and the units on the Pipe Monument mound. Owen went to work on a detailed profile of CS 2.
Once that was well in hand, it still wasn’t clear if we would be able to get home. I needed to go in to Barrow to make sure everything was progressing with the other project, so we decided I could take trailer load of field gear, samples and some of my gear back to town. That way, we would need less help getting back, and if the pickup wasn’t going to happen until tomorrow, I could bring back my sleeping bag and sleep in the mess tent.
Once I got to town, I unloaded and did some more work on the other project. It turned out that some logistics folks were available, so I went back down with them, and we managed to get everything back to town, and into the UICS yellow building. Everybody got to sleep in a real bed.
Last night was not particularly restful. The collapse had complicated matters quite a bit. However, after breakfast, we went back to work.
The old location was not viable, so I picked a new spot about a meter south, which became Column Sample 2 (CS 2). There was a bit of an overhang, and a very deep crack behind the bluff face. We needed to get all that material out of there. It took a bit of thought to figure out how to do it (not a usual archaeological operation, fortunately). Finally, we put a blue tarp down on the bottom of the main cleft so we could drag fill without anyone having to be under any overhangs or unstable areas, everybody got out of the way, and I cut the overhang back while standing as far back from it as possible. We then took the material out with a bucket brigade. Once that was done, I levered all the cracked material off, and we took it out the same way.
Once that was done, I decided that we would excavate in levels labeled with letters, so we could proceed quickly, rather than wait for Owen to try to match levels in the detailed CS1 profile, which could have been a slow process. It seemed like the fairly warm, dry weather was letting the face dry out while detailed profiling was happening, and the longer it was exposed the more chance of another collapse. Owen would do another detailed profile after we got the column sample.
I also decided to make the sample a bit smaller in volume. CS 1 we had been trying for 75 cm x 75 cm (mostly because that size fit between some prior disturbances), but 50 cm x 50 cm seemed more manageable in the time we had left. One gallon from each sub level was retained as a bulk sample, and the remainder of sediment from the sub level was screened through 1/8″ and 1/4″ mesh.
We were just getting started when someone arrived to do a coastal DGPS survey that is part of the coastal mapping aspect of the Barrow Area Information Database project. He passed on a message that said my boss needed me to come back into town. (There is no effective connectivity at Walakpa, which is why this is being posted after the fact). I reviewed recording stratigraphy (or artifacts if any showed up) with Laura Crawford, made sure everyone knew how to use the InReach is needed, and headed back to Barrow by ATV around 1PM.
Something had come up with one of the compliance projects we are working on, and I needed to talk to people and draft some documents. I made it back to Walakpa around 10PM.
On the way, I met some folks out for an evening ride, and they stopped over to visit. One of them had spent a lot of time at Walakpa when she was younger, and had some great stories. I hope we can get them recorded for future generations.
The rest of the folks had managed to complete the column sample, so we talked about closing up shop tomorrow. We just need to finish screening, record the Test Units on the Pipe Monument midden, and backfill the TUs.
Owen and Laura got up early and screened what we had dug last night. Owen worked to finish the profile. There is an apparent marine level at Level 13.
We had problems with both transit and radio batteries. Despite that, I showed Laura how to run the transit, so I don’t have to be awake all the time. We shot in the remaining levels of CS 1, as well as the new test units on the mound.
Laura and Owen continued taking CS 1 down. Unfortunately, after the dinner break, they returned to find that the bottom of the profile had collapsed.
It was a pretty depressing situation. It left an overhang, so there was no way to just continue safely. It mean that we would have to start over again in the morning.
We went to work in earnest today. Owen went to work on recording the stratigraphy of the profile we had chosen for the column sample (CS 1). I had him marking the bottom of each level so we could continue excavation even after he went to sleep. Anne Garland and Laura kept working on the tests on the mound with the monument. The SW quad of the 1×1 came down on a cryoturbated sterile layer. There was metal throughout the cultural levels. We expanded northward to examine some wood in that wall.
Meanwhile, I set up the transit and began shooting in the CS 1 profile, as well as the bluff edge. The NW quad of TU 1 had similar results, so we put some 50x50s closer to the bluff edge to see if we could find datable material and the edge of the feature.
Mary Beth Timm and I took naps, so we could stay up late and work on the CS 1 profile. After dinner, we shot in the upper levels of the CS 1 profile, as well as a polar bear jaw that was exposed in Level 12, so that it would not get stepped on. Mary Beth & I started excavating CS 1. We are excavating in natural stratigraphic levels, with any level that is more than 5 cm in depth broken into 5 cm sub-levels. One gallon from each 5 cm is being kept as a bulk sample, and we are screening the remainder.
We kept going until it go so dark that we really couldn’t see the soil colors, which was around 2 AM. We had accomplished a fair bit, so we headed off to bed.
The weather is often best at night. It was really beautiful. A pair of loons was swimming on the lagoon.
