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.
