Broda 1934 July 1 continued. road down into Mason Valley to the state highway at a school house, about 15 mi. At the school house we turned to the west to the West Walker River. We followed the north bank of this river into a gorge through which it flows from the Smith Valley into the Mason Valley. We stopped in this gorge at a point 12 mi., S Yerington, 4600 ft., W. Walker R., Lyon Co., Nevada. This site is on the river and at this place there are a number of irrigation canals leaving the stream proper. The river is bordered with cottonwoods and willows which quickly runs out a short distance from the stream into Chrysosphanums, and near desert brushes. The valley is funnel- shaped at this point. As the valley narrows the sides become steeper and higher and are very rocky. In the broader portion of the funnel on the north side there is a pocket of unsegregated boulders, rocks sand and soil, which the river apparently deposited and then later cut its way thru.
