PS. 107. 20 April 2007. Facing south, Azimuth 185. Pasture 2N. Elevation 1190 m. ISO 100, 35mm focal length, Canon 5D Digital Camera. No witness, cairn built, painted white, camera above. Good match with original (no date) and 1936 photos, note alignment of midground center Celtis patch-two large mesquite front one with forked base and straight behind one with straight truck aligned between fork of front mesquite. These all align against escarpment and distant mountains. Also, large plants on rim above escarpment in original photo are present and identifiable today. PS 108 location is in this view near left cut in escarpment. View of foreground rocks is blocked by small blue palo verde, behind that are small Celtis plants-one left and one middle, while mesquite with catclaw acacia beneath are to the right. Krameria and Calliandra common small shrubs. Prickly pear present. Lehmann lovegrass, sprucetop grama, threeawns common grasses. Distant barrel cactus in wash found in 2000 photo still present today. Compared to 2000, no important changes. M. McClaran photographer, no assistant.
