R.J.Rait 1956 32 Journal Thomas Creek, 9000+ft, Ruby Mts., Elko Co., Nevada June 17 few drifts on the trail below. The marshy area is composed of grass, skunk cabbage and a strip of willows 10-50 yards wide. It is merely a narrow band down the center of a huge amphitheater about 1/2 to 1 mile in diameter. The walls are steep and rocky with a few rock slides. The vegetation is sparse, consisting of scattered clumps of aspen and very scattered clumps of 2 or 3 or occasionally more Limber Pines. Aside from the immediate area of the marshy strip, most of the low vegetation is partially or completely snow covered. In the morning when we arrived much of the surface of the pools of the interweaving, meandering stream of the marsh was covered by a thin layer of ice. At that time I was surprised to hear the call of a Hyla from the marsh. Birds were scarce until the sun hit the area between 8 and 9 AM. Two Leucostictes landed on the snow in the bottom near the marsh and I took a shot and missed. I shot and wounded a Pika in a rock slide on the east side of the amphitheater but he got away. Calling was heard at intervals from this rock slide all morning long. I ascended farther up this east wall and shot an Olive-sided Flycatcher from an aspen in a small thicket. In a small clump of pines an Audubon Warbler was singing and later I heard them singing from an aspen grove on the canyon bottom. Warbling Vireos were singing in aspens throughout the morning.
