Rana muscosa Aug 12, 1960 Five Lakes, 1.7 mi S., 1.4 mi. W. Squaw Valley, 2500 ft Placer Co., Calif. - (cont.). lay at the edge of the channel. Towards the westernmost lake there was a grass bank 3 feet wide. The south side was a level, over-grown grass with grass and small berry bushes. There were several pines growing on both sides of the channel, but it was for the most part in the sun. The bottom of the channel was rocky, but a covering of silt 3 to 4 inches deep hid all but the largest rocks. Three logs lay completely across the channel, out of the water, forming a bridge, and east of this two more, one from each bank, lay in the water. There were a couple of smaller logs completely in the water. The frogs were found as they swam to the surface or jumped from a place of hiding. They would either swim two or three feet and rest on the bottom or would bury themselves more or less completely in the silt at the edge of a rock or log. One was chased repeatedly for about 2 minutes before it was captured, and seemed to have become quite tired when caught, as evidenced by a laborious manner of swimming and a carelessness in hiding. Although we saw only a single specimen here the first time we went past the spot, when we returned about an hour later we saw about half a dozen (got three) The five lakes drain into the Five Lakes Creek, which in turn drains into the Rubicon River, part of the Sacramento River drainage. All other Rana we took were in the drainage of the Truchee River.
