Rock Canyon

1946

1999

Description:

Plate 107. ROCK CANYON: 1946 - 1999 The view is across the upper portion of Rock Canyon below Jacks Peak. Soil erosion is active and widespread in the 1946 photo. Sometime thereafter the area was contour trenched, gully-plugged, and seeded by the Forest Service, including the area in the foreground. The aspen (Populus tremuloides) in the 1999 photo is higher than in 1946, but has not regenerated. Mountain big sage (Artemisia tridentata vaseyana), snowberry (Symphoricarpos sp.), and current (Ribes spp.) are the most common shrubs; the seeded grasses include smooth brome (Bromus inermis), orchardgrass (Dactylis glomerata), and intermediate wheatgrass (Agropyron intermedium).
