Baja 1960 Journal 35 Oct. 28 E side Isla Cerralvo, Baja Calif., Mexico +stuff (bird) shot this am. In afternoon, I hiked up to the ridge. I went by turning up the first branch arroyo to the N, off our main arroyo, then staying on the N bank of it, following along the east for a ways until the ridge turned inland, and following it to the top. Followed goat trails a good part of the way. About halfway up, saw shot a bear-tailed towhee. The ridge behind our camp arroyo turns out to be the backbone of the island. From it I could see both sides of the island, and looking W could see the peninsula forming the bay of La Paz, the Bay, and the mainland of the peninsula of Baja Calif., all N of La Paz. Came back down a very steep, rough, rocky branch of our main arroyo. The round trip took about 3 1/2 hrs. In a couple places on the way up, the Bursera and Cardon form patches of 'woodland' - tall plants openly spaced, with grass-like vegetation on the ground. On the ridges there are mainly cactus, and smaller Bursera. A fairly common, but not abundant, plant high as well as low, as in camp, is a nightshade Solanum. High on the slopes Fig; Ficus, is abundant in small plants. The very top of the ridge is fairly flat and level for 50 yds. or so with very little growth except for a grass-like plant [illegible]. Apparently the goats spend most of their time here - it is heavily grazed. There is not much
