Paul DeBenedictis 1960 Dec 11 Grand Desertito, Sonora, Mexico to Haumisillo under a creosote bush. About 10 AM Teddy woke up and I started breakfast. About an hour later the truck went on for about an hour, then 40 miles, to collect while Ted waited for John Ralph. We stopped by an over flow in the first range of mountains crossing the road. As we pulled over we saw a ground squirrel (mantled) on a rock out cropping. In the bushes near by I saw a few Urus and a snout butterfly, as well as many Vanessa cardui. I didn't catch any. I went after a few birds (especially wrens), but didn't get any. I saw another ground squirrel on the other side of the road. I missed the snout twice. About 2:10 we started en up the road a little ways; what has happened this time? Dec 12 This morning we left the campsite and went where the first mountain range crosses the road. Here we stopped & I collected a little. We took off and Ted & John caught us a little further down. We went on a considerable ways, stopping at a service station to get something to eat (squash turnover) and to Sonquita to get car permits. From here we went into the Altar Valley and ate dinner.
