Phil kept several animals, I took 2 ??, 2 ? of both species of pocket mouse to give to Duke Rogers. All others were released. Ate breakfast, etc. Left sometime in late morning, prob. near noon. Returned to Hwy 14, headed N, then E on Hwy 190. Turned S. on Darwin Road, drove 7.4 mi along dirt road to turnoff (right side of rd) to Darwin Falls. we are camping in a narrow canyon, very rocky. Gravelly, rocky soil; sparse vegetative cover of sagebrush (Artemesia), rabbitbrush (Chrysothamnus visc.), and creosote (Larrea). Arrived ~ 1530. Hiked up a narrow, rocky canyon with a stream running through it - lots of willow, some cottonwood, tall grasses, reeds, some cattail, and lots of forbs -> pervasive smell of celery in some places and abundant growth of wild celery plants. We went swimming - or rather showering - under a spectacular waterfall in the rocks about a half-hour hike from where a chain blocks the road and cars must be left. Harry Green, Kurt Schwenk
