My grandpa and uncle built a cabin on Twin Lakes over the summers with Dick Proenneke. I've got pictures of them together felling trees and hauling logs to build the cabins. Now, you can only get to the cabins by float plane.

The cabins have been taken over by the State Park now, and they've been restored too. One of their cabins is now the ranger station, and the other is kept as a "stuck in time" snapshot from the 50s and 60s. Pretty neat.
