Casto Canyon




Plate 122X. Casto Canyon 1921-2003 Viewed north across Casto Canyon from upper Mud Spring Bench to Hancock Flat. Ponderosa pine, Douglas fir, pinyon, and juniper have all increased. The original camera station is now blocked by forest growth, so the retake was made from the nearest open area. Sagebrush and bitterbrush (Purshia tridentata) have increased in the foreground except where overtopped by conifers. The dead trees just below the ridge in the original print have fallen. The site has not burned in more than 100 years. The entire area is grazed by cattle and mule deer use the shrub communities during the winter. A few curlleaf mountain mahogany (Cercocarpus ledifolius) plants also grow on the ridge in the foreground. Plates 121x and 124x were taken from the same photopoint as Plate 122x.
