WB Davis 1935. Miles 6 mi., W Murphy, Owyhee Co., Idaho, May 23. Sinkers Creek - about three miles east of Sinkers Creek, I should judge, we stopped and got one shot, but missed, the animal getting down into a burrow. We remained in the vicinity for about twenty minutes, Aldrich and Twining hunting while I attempted to dig out a burrow system. We could hear their high pitched squeak, but were unsuccessful in our attempts to bag some. The burrows here were for the most part about 60 mm in diameter and about 6 inches below the level of the soil. There were five exits to the system I was working on and each had a tunnel meeting with others which in turn entered a burrow that ran deep into the ground - I dug to a depth of two feet and it was still going down. It is this animal that is responsible for the big "colonial" mounds that one finds as often - usually deserted. At each entrance there is a little side, blind burrow - a vestibule - into which the squirrel can scurry for a hasty retreat and
