Here are some photos from Adak from early June 1984.
This is the East side of Lake Betty about 3/4 of the way down the shore.
This is Lake Betty looking North towards Finger bay from half way up the ridge to Gannet Pass. The previous photo was taken on the spit of land to the right where the "island" connects to the shore.
This is from the top of Gannet Pass looking east to Thumb and Scabbard Bays. If you drop down and go east from Gannet you will end up on the drainage into Thumb Bay (good sea run dollies in July).
This also from the top of Gannet Pass looking West to Constantine Harbor. What you see is the top of a large bench on the ridge slope and the main valley is below this bench out of view.
