Glides 1957 Razifer 2 6 July Pitnega River, Cape Sabine, Alaska of the caribou seen here. Merle says that he has never seen a herd anywhere near this size and he has had much more experience than I, yet not as much as a real Estimor. The protective cover of the Arctophila-Caret marsh has been severely damaged and I wonder if it can recover enough to provide the cover and food necessary for the summer build-up to be expected in that area. Only time and close observation will tell. I cannot help but be tremendously impressed with what I saw today which may be the only time this summer that this phenomenon may occur. Tomorrow they may be gone entirely. If I had left yesterday this factor in arctic biology would have been ignored or at best treated lightly. 7 July The caribou had essentially left by midnight. last night. I am wondering if their dropping might compare to the bounty totals of 1955 at Barron 10 July Evidence of numbers of caribou everywhere on way to Hiett's Creek. Two herds of 1045 crossed river south of camp at 1000. 19 July Camp A, Pitnega River, m. St. Cape Sabine, Alaska Tracks seen everywhere. 2 herds last night of 75 each
