DeBenedich's 1960 Dec 31 Guaymas, Sonora to Hermosillo, Sonora, Mexico About 8 we all got up after a freezing night on the desert. We lost 1 turtle, a lot of gechos, and 1 Anole and 1 chuck. We got off about 8:30, about an hour after sun rise. There is a cold northern wind, but the sky is only lightly overcast. North of Guaymas the desert is rather lush. The base plant is grass. In it grows creosote, choia and organ pipe cactuses, and sage brush. The creosote is up to 20 foot high, and often quite dense. The soil is reddish and quite rocky. No flowers here now.

Around Hermosillo the grass thins out, or at least is replaced by a very low type and the soil becomes brownish-gray. The bed rock appears to be granite rather than lava, as at Guaymas. Hermosillo is a fine clean, modern town with many new buildings and no apparent slums. We stopped about 8 miles north of Hermosillo, at the spot where the last low rocky hill crosses the highway. We had planned to eat lunch here and I thought the rocky outcroppings would make this place interesting. After lunch Gene and I went up and tried it. Just as we were about to give up, Gene got a Phyllodactylus. After this he saw a Ctenosaura tail sticking out of a crevice. This started everyone off. All in all we got 11 Phyllodactyls, 2
