Lake Dorothy Professional Review and Guide
"Lake Dorothy is the highest named lake in Indian Peaks and is likely 100 feet deep.
Most likely, Lake Dorothy was named after the granddaughter of Henry Lehman, who ranched along the South Fork of the Colorado River below today’s Monarch Lake Trailhead. When the family had to travel to Denver, they rode over Arapaho Pass, skirting Lake Dorothy, hanging impressively below Mount Neva. It is an easy walk from Arapaho Pass over tundra and rocks on a spur trail to Lake Dorothy.
Wildlife: Mule deer, elk, red squirrel, mountain chickadee, white-tailed ptarmigan, bighorn sheep, and even mountain goat reported."
