Leopold's retake of Schrader 1255 from same location
as Leopold 2, 1946.
Retake of Leopold 3/Schrader 1255; 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.
