Photo Archive No. 241.1.2010_03

PS. 241. 18 March 2010 1:00 PM. Facing southwest, Azimuth 240. Pasture 9. Elevation 1300 m. ISO 100, 35mm focal length, Canon 5D Mark II Digital Camera. Witness present, camera above. Mesquite alive; burroweed present. Prickly pear and barrel cacti. Lehmann lovegrass dominant, also find scattered cottontop and sideoats grama. Not happy about match with earlier photos, the actual location is probably 5 m upslope to the east; however, it is still possible to follow fate of the larger mesquite from this location. For example, the large mesquite in the left center today, was at the center of the 1948 image, and the large mesquite at the far right today, had only the edge of the canopy visible in 1948. Pipeline construction 2005 disturbed foreground. Windy conditions. Compared to 2007, less grass; and more litter because of dry conditions in summer 2009. M. McClaran photographer, A. Dalke assistant.

For example, the large mesquite in the left center today, was at the center of the 1948 image, and the large mesquite at the far right today, had only the edge of the canopy visible in 1948. Pipeline construction 2005 disturbed foreground. Compared to 2010, more grass cover, (mainly Lehmann lovegrass), the two barrel cacti no longer present under mesquite on left, increase of prickly pear plants and size, pipeline disturbance is becoming more difficult to discern.
