June 2, 1935 I traversed the crest of the ridge hunting both squirrels and Marmots at each rocky point of which there are 7 or 8. I shot one large Citellus of the usual kind, with conspicuous long, bushy, grey tail. Close by, and a short time later in another rock pile I shot a similar squirrel but smaller and with a short scant red tail similar to Citellus organus. Marmots were occasionally seen in the rocks, but I was unable to approach close enough for a shot. At the termination of the ridge as it dropped off toward the saddle between Mount Harrison and Thunder Mountain I found a rocky point dropping off in cliffs about 50 feet high to extensive talus slopes below. By careful stalking methods I was able to secure a large female Marmot as she was descending the vertical face of a cliff. She was very much lighter than any other Marmot we have collected, with a light red tail, very long, but not dense pelage, and with less white on the head than other marmots I have seen. I saw several Golden Mantled Ground Squirrels on the talus below the cliffs. Rock Wrens were common here, and I watched a Spurrow Hawk executing some amazing diving manoeuvres above the cliffs. In the way back to camp a white tailed Jack rabbit ran swiftly along the forest's edge and disappeared in the trees. Set out 11 trap this evening, 25 pieces a foot, in Artemesia only. June 9, 1935 Caught 2 Peromyscus in the trap line. Shinnal
