In the year 1873, a division of geologists under the management of Dr. F. V. Hayden, made a survey of the region from Willow Creek Pass, between North and Middle Parks, across the park range down the Yuma or Bear River to the White River, around to Eagle River and up the Grand, of which Willow Creek, in Middle Park, is a tributary. In this report, very brief mention is made of Steamboat Springs, although the trail on their map does not pass nearer than twenty-five or thirty miles to the Springs.
