Pine Spring Knoll
Plate 1308X. Pine Spring Knoll 1942 – 2006 Viewed northwest across the head of Crystal Creek on Cedar Mountain. Pine Spring Knoll (10,023 ft) is on the left, while the Three Knolls are to the right. Day Spring is located near the log cabin in the 1942 image. The foreground is less heavily grazed today than in the past. The low shrubs in the distance are snowberry and they appear to have increased. Aspen around the photopoint and in the distance has successfully regenerated. This is most likely due to the private landowners switching from domestic sheep to cattle (Ohms 2003). Forbs have also increased in the foreground, as would be expected when sheep are replaced by cattle - - - sheep tend to graze woody species and forbs more readily than do cattle. This may also explain the spread of snowberry. Conifers on the distant knolls have increased.
