VEGETATION Map oF A SQUARE MILE IN NORTHEASTERN LARIMER COUNTY, COLORADO 
Contour intervals 50 ft. Unmarked areas are grassland. At the western edge of 
the section are low granite hills with a sparse covering of pine and some scattered Cerco- 
carpus and some other bushes, with grasses and various flowering herbs (Foothill Forest 
Formation). To the east of this is a lateral valley with fine-grained soil supporting a grass- 
land formation. Farther east is a series of sedimentary ridges. At the northeast of the 
section is a steep gulch with flowing water. Attention is called to the patches of Upland 
Dry Grass Formation scattered through the sedimentary area and especially to the sharply 
marked western boundary of the Cercocarpus Formation. The rock ridges of the eastern 
part of the section contain lime salts and here even the Cercocarpus bushes are widely 
separated and there are very few grasses and other herbs.
