trails make it possible for one To get through the brush and make sets for Sigmoidon and Peromyscus, but ants are found here by the millions and unless one gets to his trap shortly after the animal is caught the ants will have done their "dirty work". Under and about lava rock ledges are places here frequented by Urocyon. In some of the ravines on the south mountain slopes the sub-tropical zone up sometimes as far as 3300 feet, where the trees are full of fresh green foliage but the old rocky stream beds are dry and alive with ants. The vegetation on the north slope changes near the mountain top from the sororan glass to low brush which within a few feet becomes higher until it passes into the true sub-tropical zone or the upper extremity of the coffee. Along this upper ledge much young coffee is being planted and under large lava rocks boulders in the shade of big green tree Pine Peaks Peromyscus are common.
