Cogswell 1949 Journal 140 Dec. 22 Glendora, Los Angeles Co., Calif. (cont'd) Monroe Canyon on a map which is 1/8 mi. to the W. I investigated areas along the 3100 ft. contour level trail on the N.E. facing slope. There are semi. barren ("sagebrush"), adenostoma-Cerco- carpus-Ceanothus crassifolius, and scrub oak - Ceanothus - [illegible] types -- several possible areas here. Birds were more active here in mid p.m., warblers & Calif. thrushers singing; Scrub Jay, Bush Tit, Red-tailed Hawk, & Fox (?) Sparrow noted. In the dirt road or firebreak on the ridge 1/8 mi. from the paved Glendora Mt. road we found a measured several tracks of a Mountain Lion [see sp.acct]. Several Brush Rabbits were seen in the less dense chaparral or "sagebrush" areas. Dec. 23 This q.m. I investigated some chanise- sagebrush - sage areas on the lower slopes of the mountains due N of Glendora. These are comparable to a medium height - medium density chaparral, though really in an [illegible] ecotone zone between true sagebrush & true chapar- ral. I reached the trail (Engelwith Canyon) from the Snidow Ranch, but found later it would be more convenient from end of the road just to the east in the mouth of the canyon - This seems to be the most accessible extensive area of ungrazed sagebrush nearby.
