the area, especially in the vicinity of Berenice. Little Lost River is hardly more than a creek now for practically all of the water is diverted to the fields, alfalfa being the chief crop. No water reaches the "sinks" - a condition like that of Big Lost River. The Lemhi mountains - to the NE - and the Lost River Mountains - between Big and Little Lost rivers - rise abruptly and are barrow of trees, save in occasional favored slopes near the crest. The slopes are exceedingly steep and rocky and deeply eroded. At the base of the mountains wherever a canyon enters the main valley alluvial fans are prominent - these areas are termed "benches" by the local residents. Mr. Peterson told me that a government trapper who operated a string of traps from Twin Falls to Howe during the winter of 1934-35, had averaged about 200 coyotes per month. He used poison almost exclusively.
