Blade of former witness post is present next to cairn. Matches all photo directions very well. Mesquite, catlcaw acacia, ocotillo, Calliandra, Krameria present. Prickly pear present. Also shrubby buckwheat. Lehmann lovegrass is only perennial grass. Mesquite in 1936 photo are still present, although second tree from left (behind ocotillo) might be dead now, there is certainly evidence that mesquite size has diminished with partial diebacks. Ocotillo present now, are not visible in 1936 or 1956 photos. Compared to 2000, much less grass, mesquite less vigorous. M. McClaran photographer, no assistant.
