1927 Volcano Santa Ana, Dept, Santa Ana, Salvador May 11, 1927 - Today I put out a trap line on the volcano Santa Ana proper in the Department of Santa Ana. The first line I was put out at an altitude of 6150 feet in the semi-humid forest on the north slope. The vegetation was somewhat heavier here than on Cerro Los Yarayos, also there were more ferns and mosses. Snap traps both large and small were set at the base of trees and under logs (in among the ferns). The second trap line was set out at an altitude of 6800 feet, where I set all the snap traps both large and small in brush like trees full of trash and parasitic plant roots. This association is just above the semi-humid forest and continues on up to the crater with the brush gradually giving away to grass or grazing land.
