Mayhew 1961 Aug. 21 Journal 69. Glamis area, Imperial Co., Calif. Calexico on highway 98. We weighed, measured & toe-clipped 11 immature Uma notata at the Glamis Store after lunch, then released them in the dunes as we drove through to Calexico. I wanted to check some roads in that area to see if they might yield some Phrynosoma micelli. Gravel trucks make collecting on the Glamis-Brawly road rather hazardous, so I am looking for a place that has these animals, but no gravel trucks. We drove over highway 98 from a point 11 miles [illegible] of Calexico to 26 miles east, but the terrain doesn't seem sandy enough to support a large population of P. micelli. None were seen, even though we drove between 5 & 10 mph. Another road also was checked. This is south of the All-American Canal, & is the remains of the old Yuma- El Centro Highway. We drove 8 miles of this road without seeing any P. micelli either. Again, it appeared to be too gravelly for good P. micelli country. Then we drove across the Algodones Dunes on Highway 80. Thunder showers could be seen all
