J.G. Hall 1952 June 25 Independence Lake, Sierra Co., Calif. base of the cut. There are few small trees (aspen) right in the heart of the colony but much that is smaller is near- ly + appears to be available w/o much overland travel. Willows extremely thick at borders of stream and the beavers are making some use of these. In one clump of willows a canal 4 or 5 feet long had been cut from the water's edge. On the ground at the end of this canal was a pile of peeled logs or sticks, STREAM mostly an inch Canal + less in Willows Willows drain. {pile of peeled Didn't have sticks} time to examine it closely or to determine whether these sticks were mostly aspen or willow, tho' they were probably willow since I found a similar "feeding platform" at the rockslide colony and it too was in a willow clump. There are 3 or more fair-sized dams and they appear old & well-maintained. Good layers of silt in pools above the dams. The fish seem to have no V 10
