Walakpa Zooarchaeology

Last week I went to the Alaska Marine Science Symposium 2017 meetings in Anchorage.  I’ve never gone to those meetings before, but we were presenting two posters on finds from Walakpa.

One was on the results of the necropsy of a mummified seal found in a 1944 ice cellar.  I was excited about it because it was pre-bomb with a pretty tight date and therefore helpful for refining radiocarbon correction factors.  It turns out to be the first mummified seal reported from anywhere outside the Dry Valleys of Antarctica!  Who knew?

The second was presenting some preliminary results of investigations on a polar bear skull which eroded from Walakpa, and was recovered and turned in by Kenneth Brower.  It turned out to be somewhat unusual in shape, as well as being really big (maybe the 4th largest ever measured).  That bear must have been HUGE!

A hundred and one (roughly) moving pieces

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.

Beach just south of Hollywood.  We got as far as the snow in the distance.

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.

In Fairbanks, looking for walrus

After a rather long, drawn-out saga, everything is in place and I can draw on funds so I can work on the WALRUS project.  The delays have been really frustrating for everyone involved.   Once I get the interns on board in Barrow, we’ll get back to going through the faunal material we have there for walrus samples.

We are trying to get samples from a wide range of sites.  Since the sampling is destructive, we don’t want to use artifacts if that can be avoided.  Ideally we want  unmodified walrus parts, bone or tooth, or if we can’t get enough of them, manufacturing discards.  As a fallback, we may wind up sampling things like shovels or bola weights, assuming we can get the museum’s permission, since they are common types of artifacts, and not diagnostic (or something that is likely to be displayed).  We currently can’t use tusk parts, since there have been no modern studies to compare their chemistry to that of bones and teeth, so interpretation of results would be problematic. (If any carvers would be able to contribute some scraps from tusks along with a sample of bone and/or a tooth from the same animal, it would be a really big help).  We are also looking for caribou or some terrestrial plant material from the same place in the site for radiocarbon dating, since marine mammals incorporate old carbon and the dates are hard to interpret.

More recent archaeological projects tend to have excavated faunal material in the same way as everything else, with decent stratigraphic control, and also tend to have brought it back from the field.  However, in the early days, that was not often  the case.  Even if material was brought back, it often wasn’t cataloged in any detail, so reports are almost no help in figuring out if there is any walrus to be had in archaeological collections.  A bit of walrus shows up in catalogs, but most of it is in the form of artifacts.  A lot of walrus artifacts (particularly bone, since ivory was clearly an item of trade) suggests that the inhabitants of a site were hunting walrus, so the potential for walrus parts to exist in the collection is there.

Many of the classic sites on the coast of  Alaska have strong indications that walrus were being caught by the people who lived there, but they were excavated decades ago, and finding suitable samples in the collections was not something that could just be done by getting someone to pull a particular bag or catalog number.  It pretty much requires looking through mixed lots of artifacts and bags of bones.  So I’m in Fairbanks doing just that.

We are mostly working in the museum, but it is closed on the weekend, so we got  permission to bring a collection of faunal material to the PI (Nicole Misarti)’s lab, and we went through it yesterday.  It took some doing, but we got though it, and should have plenty of samples.  It was an adventure.  We had 24 boxes, most of them full of bags like this:

Nicole holds a bag from which the bones on the tray burst forth when she took it out of the outer bag.
Nicole holds a bag from which the bones on the tray burst forth (like a scene from Alien) when she took it out of the outer bag.  Sadly, these were almost all ringed seal parts.  Other bags from that box are on the right.

Not all of the bags were correctly labeled, or at least the labels often didn’t specify species, just element, so we had to look.

We found a few other interesting things in the process, including this really large fish bone from Point Hope.

Really big fish bone.

I’m pretty sure it’s some sort of cod (Gadid) but exactly what sort?  It’s really big.  If I have time, I’ll talk to the curator of fish, but the mission is walrus samples at the moment.

A book about Nuvuk

I made it back from DC on Thursday night.  Friday was the usual scramble after being out of town.  Saturday night was the annual meeting of the Friends of the Library.  There was a business meeting, and a potluck dinner.  But the highlight of the meeting was the guest speaker, none other than Daniel Inulak Lum, author of the book Nuvuk, the Northernmost: Altered Land, Altered Lives in Barrow, Alaska.

Dan’s family is Nuvukmiut (that’s how it is spelled in Nuvuk dialect–it would be Nuvugmiut in Barrow dialect), originally from Nuvuk.  He ran a tour company which took tourists to Nuvuk for much of the time the Nuvuk Archaeological Project was active.  While doing that, he wound up taking a whole lot of pictures.  He has some really great animal photos, particularly of bears, as well as some really beautiful landscapes shots.  His family had to move to Fairbanks for a while for reasons connected to health of a family member, so he isn’t running the tour company any more, but it gave him an opportunity to look through his pictures and he wound up writing a book about Nuvuk and life in Barrow.

When he was running the tour company, Dan gave great tours.  He really wanted to pass on accurate information to his clients, and would stop at our excavations and talk to us, so he had the latest news.  As he said in his talk, the village is no longer there (due to erosion) so all the Nuvukmiut have to remember it by is information from oral history and archaeology.  He’d always check to see if it was OK to bring the tourists over (not if we were excavating human remains), and was always willing to bring things back and forth for us in his van.  When the Ipiutak sled runners were uncovered, Dan  stood by until we had them out of the ground around 2AM (despite having had tours all day) and then drove them very slowly back to the lab at NARL, making sure that they weren’t bounced around.  It took over an hour to go the five or so miles.  He also brought pop out for the crew on warm days.

Dan showed slides of many of the photos from the book, and talked about how he came to write a book in the first place.  He was very encouraging to audience members about writing and publishing their own books.

I’m going to be spending a good bit of time getting ready for International Archaeology Day, which is Saturday.

A bit more about Iñupiat subsistence whaling

My post on the Anagi crew’s whale has gotten a number of comments from people who are interested, one way or another, in whales.  Some of them are genuinely interested in learning more about whales & Iñupiat whaling; others appear not to be.  I’m going to try to answer some of the questions, and provide links to sites that can give even more information.

But first,  see this Public Service Announcement.

OK, now a bit of history.  Alaska Natives (and in fact many other Native Americans and Canadian First Nations people) have been whaling for 2000 years or more, since before the Thule culture developed, based on archaeology.  Aboriginal whaling did not damage the whale stocks in any way that can be detected.  What damaged whale stocks was European (and later Euro-American) commercial whaling.  The bowhead was popular with commercial whalers because it was non-agressive and had a lot of blubber for whale oil, plus long baleen.  Most Eastern Arctic stocks were decimated by the early 19th century.

In the western North American Arctic, commercial whaler Thomas Welcome Roys first cruised north of the Bering Strait in 1848, starting a rush to catch the plentiful and naive Bering-Chukchi-Beaufort stock of bowheads on which so many coastal Alaska natives and their inland trading partners depended.  The whales soon became skittish and scarce and many Alaska Natives died of starvation.

Once oil was struck in Pennsylvania, one of the big reasons for hunting whales diminished.  But the baleen, the plates in a whale’s mouth that they use to filter-feed, was still valuable for buggy whips and corset and collar stays.  Bowheads have by far the longest baleen of any whale (15 feet or more from a big whale), so they were still hunted until those items were no longer in fashion or needed.

Many coastal Alaska Natives had become involved in commercial whaling, including shore-based commercial whaling carried out with traditional Iñupiat techniques with Yankee style harpoons, to support their families.  After commercial whaling ended, coastal whaling communities continued these hunts, combining traditional techniques and traditional and modern technology.

In the late 1970’s, some Western biologists, who were not experienced in the Arctic and knew little about bowhead whales (biologists didn’t back then) tried to count bowheads.  They believed that the whales were scared of ice!  They thought the bowheads had to travel in a lead and would come up to breathe in the lead so they could be counted.  Even if that were true, they didn’t account for the fact that there are multiple leads, and that the whales only have to breathe every so often and that wouldn’t necessarily be where the observation post was.  They came up with a count of several hundred whales, and of course, sounded the alarm.  A moratorium was declared on Alaska Native whaling in 1977 (years before the moratorium on commercial whaling, I might add).

Since many families got (and still do get today) a significant portion of their meat from whales, this was a huge problem.  Although wages may look high in places like Alaska’s North Slope, costs are high too, and many families do not have someone who is working in the cash economy and can afford to feed a family on store food and whatever else they can hunt (and of course full-time work does interfere with hunting, which was traditionally a full-time occupation itself).  Most Iñupiat had never heard of the International Whaling commission, and couldn’t understand why they felt it appropriate to starve human beings by forbidding them to feed themselves.

They were particularly puzzled because senior whaling captains and hunters who had spent many decades on the ice had observed that the bowhead population appeared to be growing from the depths it had sunk to by the end of commercial whaling.  They knew that bowheads are not scared of ice.  In fact they can breathe under quite thick ice (they become positively buoyant and use the bow on their head where their nostrils are to push up the ice, cracking enough to let air into the little tented space formed under the ice and breathe there, and then submerge and go on about their business), and that they would not restrict travel to the near shore lead, so they knew the count was wrong.

The North Slope Borough Department of Wildlife Management, with many cooperating researchers over the years, has been studying bowhead whales ever since.  They soon developed a much better way to count them, which is continually refined.  Counts now show an annual rate of increase of 3.2%, which is really high for such long-lived animals.

The Alaska Native Bowhead hunt is highly regulated.   The Alaska Eskimo Whaling Commission (AEWC) manages the hunt under authority from the US government.  There is a quota of strikes (not whales taken, but whales struck so there is an incentive to land every whale struck if humanly possible), which is established based on document subsistence needs of each whaling community, in light of the population estimates. This quota is set so that communities get what they need and no more.  The harvest is considerably below what population biologists would consider a sustainable harvest if they were talking about elk, or caribou, or mule deer.  As long as something else, like marine noise or a massive oil spill in Arctic waters, doesn’t come along and decimate the population the way commercial whaling did, this is absolutely a sustainable harvest, carried out by people who entire culture is centered around that harvest.

The AEWC divides the quota between communities, based on active crews and population, and approves the transfer of strikes between communities (if, say, the ice is bad in one place and they can’t catch whales, they may transfer their strikes to a place with better conditions) since the maktak and meat is shared and everyone on the North Slope and beyond benefits if whales are taken.  Only captains and crews registered with the AEWC are allowed to take whales, and violations of rules, ceasefires, etc can and has led to punishment or suspension of the offending captain.

When a whale is taken there are traditional rules for sharing which vary by community.  In general, specific shares go the captain, the boat (itself–although obviously the boat owner disposes of the boat’s share), the harpooner, the other crew members, and the other boats which helped tow the whale back to be cut up.  Anyone who shows up to help with the butchering (even a little) gets a share.  My daughter helped a very little once when she was about 8, and she came home with a small share.  The captain’s wife and her helpers cook round the clock after the whale is ashore, and when they are ready, the captain’s flag is hoisted and anyone who wants can go and get fed (they will usually send to-go plates to house-bound Elders).

After that, the captain and crew get ready for a celebration where a great deal more of the whale is shared with whomever shows up.  People get whale meat, maktak, kidney, intestine, tail, flipper, gums, plus goose soup, mikiaq (whale blubber, meat & blood, fermented–and before you say gross, when was the last time you ate curdled drained milk with mold on it–AKA a nice Stilton or Brie?), rolls, cakes, fruit, etc.  Most families in the community go to at least one of these every year.  Many go to all of them.  The amount given to each person depends on how many in the family (and the servers pretty much know or the people sitting around do, so no one fibs).  Captains also give out meat & maktak at Thanksgiving and Christmas feasts to whomever shows up (usually much of the community), and usually will provide some for potluck and other festivities as well.  They also share with Elders & folks who need it during the year.  Most of the folks with whom it is shared share it farther.  Shares travel to Anchorage and even to the Lower 48.  Some of the people who get shares send back things like berries or smoked salmon from their area, or caribou from the interior.

None of the whale, or any other marine mammal for that matter, can be sold, with the exception that Alaska coastal Natives can use baleen or bone or ivory to make handicrafts, which they then may sell.  They are not allowed to waste the rest of the animal just to get these products.

There is a great list of links to good solid information on the bowhead whale and bowhead hunt here.

A bit of interior decoration

We’ve added a couple of new student hire for the summer, but still have room for one or two more, so if you are interested, get in touch ASAP!

With the larger crew, we have been working on getting some of the Pingusugruk collection sorted and in proper archival boxes.  We need to move the container it was in, so we’d have to move the boxes anyway, and this way we can not only record which bag is in which numbered box, but also sort the “Tamis” bags, which are the 25% random sample drawn at time of excavation from the rest, to make future analysis easier, and find the rest of the bags from the column sample that Rebecca Connor & Angelique Neffe started on, so I can finish that analysis.  Most of this work is being done by our adult volunteers.

The students worked on this a little, mostly to get it set up so the volunteers can work easily, and also to get more room on the lab benches, so that they can work on the Nuvuk materials with no chance of things getting mixed up.  In the process, we had a number of animal bones that were collected on the beach or tundra and donated to us.  Some of them have been labeled as to species and element, and are being used to help with the preliminary sort and cataloging of the materials from Nuvuk Locus 6 midden.

There were a few things which were sort of superfluous, like a caribou skull.  The students really wanted to use it as a decoration, so with a little glue to keep the teeth in, it was suspended outside the door (using peel-off hangers of course to avoid damaging the wall.

Apparently, they found something else they felt was not necessary to include in the comparative collection, either because we haven’t found any (we haven’t) or because they figure everyone already knows what it is.  The next day, this is what the door looked like.

A not so quick trip to Nuvuk

I got out to Nuvuk today for the first time today. The ARM project that we support want to put a flux tower at the Point to measure flux off the ocean during the open water season.  The thing is that the ideal spot for the tower is on the ridge where the Nuvuk site is.

In the past, other folks wanted to put flux towers there, but there simply wasn’t room for a tower in an area where we had already tested and recovered all the burials, and we didn’t want to chance disturbance to a burial.  Now we’ve gotten a good way ahead of the erosion, so it seemed that it might be possible.  However, I didn’t want the tower to be on top of the possible Ipiutaq structures, just in case funding for their excavation is available.  Since the tower installation involved moving a little gravel, it was important for me to be there just in case something showed up.

It took a while to get out there, since the ARM Kubota is on tracks and can only go about 15 miles an hour.  We quickly got a spot picked for the tower.  After that, I spent most of my time looking around for bears while the others started putting the tower together.  I spotted 2, a mom and a cub, who were heading to the bone pile.

We decided to use sandbags for the guy-wires and then added some more on top the tracks on the base plate.  To minimize disturbance to the site, we decided fill the “sand”bags with beach gravel, and bring them up with a four-wheeler.

“Sand”bags on the Honda.

After the tower was assembled and the instruments were on, the instruments needed to be wired up.  That took a while, but I had to sick around since one of them needed to look down are gravel, so we needed to cover the plywood base plate, which meant more digging.

That gave me time to check out the area where we salvaged the Ipiutak structure last fall.  Good thing we did that last fall, because that area is gone.  There is a big notch in the bluff there, and that’s it.  It would have been a pity to lose that, because we found some very interesting things in the field and in the lab.

Where the Ipiutak structure was…

While I was getting to play, the crew was working away in the lab.  They have finished floating and sorting the materials from the fall salvage, and are moving on.  Over the winter, we’ve had several sets of visitors on short notice, which required some materials to be cleaned off benches fairly quickly.  As a result, there were a lot of miscellaneous boxes around the lab.  The crew has reorganized several cabinets and gotten most of the boxes emptied. There is plenty of bench space, so we are moving on to cataloging and marking.

About those gray whales that got stuck at Barrow a few years back…

I’ve noticed I’ve been getting more hits on search terms relating to those whales, probably since the movie “Big Miracle” just was released.  So, since I’m kinda busy with the Super Bowl, I thought I’d put up a few links to the real story.

1) Bill Hess’s blog, where he is doing a series on the whole event.  Bill took what were probably the first professional pictures of the whales, including some may probably recognize.  This features a lot of Bill’s really fine photographs.

2) An article in the Fairbanks New-Miner which has interviews with many of the folks in Barrow who were involved in the original event, including biologist Geoff Carroll.

3) An article in the Anchorage Daily News by Richard Mauer, who covered the original story and hauled out his notes to write this one.

In Praise of Dolly Vardens

I was going to continue the story of the trip to Wainwright, but then there was a knock at the door.  Mike & Patsy Aamodt have a net out by Nuvuk, and often stop by to check on the proceedings (Mike was once an archaeologist, among many other things). They stopped by on the way home from checking their net, and were kind enough to share two Dolly Vardens from their catch.

They were alive until a couple of hours ago, and one went straight to the oven and the other got vacuum sealed and went straight to the freezer.

Super tasty!  Thanks so much to Mike & Patsy!

Dolly Varden “trout” are actually char and can either be sea-run, spending part of their lives at sea, or landlocked, spending their entire lives in freshwater.  The name comes from a character in a Charles Dickens novel, who had a polka-dot dress, and after whom a type of 1870’s fashion was named.  The fish was probably named after the fashion.

I am going to save the skeleton for a comparative specimen.
