Hoffmeister 1939 Ochotona princeps July 13 1 mi. SE Sunnoot Mtn., 4200 ft., Skamania Co., Wash. The party stopped for about 1½ hours (12:30 - 2:00 P.M.) here where there are extensive rock slides above and below the road (to Mosquito Lake and Twin Buttes). Ochotona were numerous in the slides, as could be determined by their calling. The weather was cool, cloudy, and with a few drops of rain. Shot one specimen that sat up on the rocks about 25 feet from me, using a 16 gauge 10 wood shell as I had no .410 auxiliary barrel in the gun. The shot completed destroyed the head of the animal. Small bunches of grass around the edge of the slide, and also within it, show were I think Ochotona have been eating. Apparently they prefer the young ends of the glass stems, as these were eaten off. The bunches of grass were cut thus: [symbol], giving an effect like this [symbol]. I could find no places where the glass had been stored in piles.
