Aug. 14, 1960 Truckee River S of Squaw Valley Road, Placer Co., Calif: swift rocky stream to a wide, marshy-bordered river to an alder swamp. We collected in the area along the transition from rocky stream to grassy marsh. We first stopped at a place 0.6 miles (by road.) beyond the bridge where Calif. 89. crosses the Truckee River. Here the river was very wide, and, although the main stream was moving quickly, there were numerous areas of slower moving water, often with a dense growth of glass on them. The border of the river we were on varied in width from the width of 89 (30 feet?) -plus 6 yards to the same put 30 to 40 yards. About a half mile up the river is a restaurant. Between this and the spot we parked the River is wide, bordered with tall grasses, alders, poplar, and willow, the trees growing at higher spots. There were a few flowers along the highway, and a rock-covered trail along the river, and most of the vegetation is green. Above the highway there is dry, scrubby pine forest, with a few pines by the river. I had hoped to see some herptiles, but although we even looked under logs and rocks, we saw none. Numerous insects and small fish were in the water, and it look suitable for frogs and toads along here. We saw a B pine white along the restaurant, which flew up into a tall pine tree and Tony got a saepium and I got a Skipper and a J M.toura spinetorum in the mud along the river by a willow thicket. It is the best catch so far, and the only one we saw. Working towards the bridge we passed through an alder thicket to an area where the river became swifter & rockier. The alders gave way to a growth of golden rod along the highway. In this we got avota, saepium, & skippers. Up along the highway.
