LOOKING GLASS ROCK FROM THE SOUTH
General Description: This northwest view of Looking Glass Rock was taken
from private land looking across BLM and state lands. Both the original and the
repeat photographs were taken with an 80mm lens, thus Looking Glass Rock appears
much closer than it actually is.
Soils: Deep Begay fine sandy loams are found on this site. These soils
have effective root depths of more than 60 inches with moderately rapid
permeability.
Precipitation: Average annual precipitation at Looking Glass Rock ranges
from 10 to 12 inches.
Legal Description: NW1/4NW1/4 Section 21 T.29S., R.23E.
COMPARISON: Plant density and ground cover appear to have slightly
increased since 1927. The most striking difference between the 1927 and 1999
images is the increased plant health and vigor in the 1999 scene. This site
supports a diverse plant community of big sagebrush, fourwing saltbush, Mormon
tea, Fremont barberry, Indian ricegrass, curlygrass, needle and thread grass,
squirreltail, blue grama, sego lily, groundsel, globemallow, Hopi blanket
flower, lupine, pinyon and juniper.
