Cabezon Peak as seen from the town of Cabezon, 1911. Note that Rio Puerco is incised at this time. Compare to similar view (below) before incision. Distinctive Cottonwood Trees can be seen near River in both views.

Retake of Schmidt/Lee 696; 7/3/98. Cabezon Peak from just north of Cabezon Village. Most notable change is widening of Rio Puerco subsequent to incision, and incision of small tributary to south of river. This tributary is presently a discontinuous gully and there is no evidence that it was ever graded to the main stem. This fact points to some incision-causing force that worked on different scales in both time and space. Other changes shown include the cessation of agriculture (corn(?) is growing in Lee's view) and the disappearance of the cottonwood.
