Hawthorne, m.s. 1974 Journal 16 September (cont) 16 mi. W. Hawthorne, 5600 ft., Lyon Co., Nevada A short time later I saw a rather large (≈200 mm) crayfish with conspicuous yellow bands on its claws. We saw evidence of recent Beaver (Castor) work or logs nearby the river and later exploration found many more knawed logs and fairly recent Beaver runways in the grass. A sample of the knawed wood and leaves from the dominant trees were returned for further information. 1600 - we set 140 live traps on the east side of Walker river at a point 13.5 mi. North and 18 mi. West of Hawthorne, Nevada. Although the habitat looked somewhat unfavorable for Microdipodops, we choose a wash that looked reasonable good (i.e. Sandy soil). We then drove back across to the west side of the river and returned [illegible] to a point 4.5 mi. N. and 20.5 mi. W. of Hawthorne, Nevada where we set 160 live traps. This latter area looked much better for finding Microdipodops although it was separated from other favorable habitat to the N. by rocky soil and separated
