Many different wildflowers are found in the understory of aspen groves in the Rocky Mountains in Utah. Some of the more common species are the fireweed, columbine, geranium, and blue bells. On the Wasatch-Cache National Forest, a new addition to the Research Natural Areas (RNA) system has been established.

Walter F. Mueggler – Butler Fork RNA
This addition to the Research Natural Areas (RNA) system on the Wasatch-Cache National Forest is the Walter F. Mueggler – Butler Fork RNA. It is approximately 1,270 acres in size and occurs in the central Wasatch Mountain Range of north-central Utah. The RNA is located in Big Cottonwood Canyon within the Mount Olympus Wilderness Area, southeast of Salt Lake City.
Named after the renowned aspen ecologist Walt Mueggler, this area is dominated by quaking aspen. The area has not experienced grazing in over 100 years, which is very uncommon in this portion of Utah, and shows no impacts from any historical uses. The rich herbaceous undergrowth truly represents the potential of aspen communities throughout northern Utah and adjacent Rocky Mountains states.
