Murray 1948 Journal Apr 20 Alaska, 4400 ft; Baja California mexicani, and Lewis found gophers working. There was an olive sided flycatcher nearly. At about 1 PM we started off on the Tecate road, still nursing the International. It was fairly level for a while, passing through some areas which were white as snow with granite rock. Most was a light growth of scrub oak, juniper, agaves and cholla - some grassy slopes. Saw a jack rabbit and California ground squirrel up higher. Began an even gradual descent through chaparral growth, much of it dense Adenostoma with sage brush and considerable short grass. Then entered a thick "forest" of another form, Adenostoma sparsifolia or red-shank. This is leafed only on the upper branches and grows from 4 to 7 feet high. We camped for the night in a clearing beside a dead cow and a spring. Put out 50 live traps and 50 museum special mouse traps, all in the thick Adenostoma. Followed a narrow sandy creek bed most of the way with the live traps and cow trails with the others, otherwise it would have been tough going indeed Dr. Benson has soldered a hole in the gas line which was undoubtedly the trouble.
