(Schrader 1255)

Retake of Schrader 1255/Leopold 3; 8/6/98. The most startling feature of this set of photos is that the Rio Puerco appears to be unincised in Schrader's view. Leopold's view is somewhat hazy, but the Rio Puerco appears - based on the position of the base of trees - to be moderately incised along a line between the clump of trees in the middle distance and the single prominent cottonwood in the right middle ground. The arcing green strip to the west of the Rio Puerco is undoubtedly the trace of the acequia (irrigation ditch) that was fed by the San Luis Dam - the last dam maintained on the main stem of the Puerco. The modern river is incised 20-35 feet in this reach. The number of cottonwoods along this reach decreased between 1905 and 1946 and has since increased dramatically.
