feet up behind a curled up section of thin bark on a dead lodgepole pine of about 10 inches diameter; mounds of snow all about; adjacent trees, hemlocks and red firs. Bird comes with bill-full of insects, and I can see the usual mass of twigs under the open side of the lifted park. 2:45 p.m. - At about 7500 ft. alt.; off the trail to the west, in one of the heads of Martin Creek; a ledge of rock along the western wall of the canyon has broken off to form a long talus slide, rocks up to a yard or more in diameter. Here, as I hoped, I hear conies in the typical association for them. At the fast of the Talus apron the snow is just going, but a little grass is coming up; also among the lowermost rocks some stalks of red elderberry are showing leaf; out from the Talus are mats of the prostrate arctostaphylos nevadensis; up along the ledges I can see clumps of red cherry and chinquapin; the trees about are red fir. I hear a Rock Wren singing ventriloquially from the rim-rock, which is well provided with crevices and caverns. This may prove to be the westernmost station for conies in the Lassen "section." 3:50 p.m. - Down to about 600-foot level, having come thru willowy meadows, with the grass barely above the earth, yet bands of restless cattle already run onto them, to keep them grazed and trampled down and the willows browsed up to 5 feet or so, and no chance for young shoots to start.
