Uintah County




Archeologic evidence suggests that portions of the Uinta Basin have been inhabited by Archaic peoples and Fremont peoples. By the time of recorded history its inhabitants were the Ute people. The first known traverse by non-Indians was made by Fathers Dominguez and Escalante (1776), as they sought to establish a land route between California and Spanish America.

By the early nineteenth century, occasional fur trappers entered the Basin. In 1831-32 Antoine Robidoux, a French trapper licensed by the Mexican government, established a trading post near present-day Whiterocks. He abandoned the effort in 1844.

In 1847 the Great Salt Lake Valley, still a property of Mexico, was first colonized by Brigham Young and his followers. In 1861 Young dispatched an exploring party to the Uinta Basin; they reported that “that section of country lying between the Wasatch Mountains and the eastern boundary of the territory, and south of Green River country, was one vast contiguity of waste and measurably valueless.” Young made no further effort to colonize the area.

G.K. Gilbert Geologic View Park

Grove Karl Gilbert (1843-1918) is considered one of the greatest American geologists, having pioneered many theories in the earth sciences.  In the late 1800s and early 1900s, Gilbert advanced concepts of mountain building, fault scarps, earthquake probabilities, and lake cycles that have withstood the test of time and are still used today.  Furthermore, Gilbert applied science toward promoting public welfare by advocating the need for evaluation of risks and public disclosure of geologic hazards.

Utah was one of Gilbert’s favorite study areas where he formulated many of his theories.  He spent much time at this particular location and was the first to establish that Little Cottonwood Canyon and Bells Canyon glaciers descended as far as the shoreline of ancient Lake Bonneville.  Gilbert was also the first person to recognize the earthquake hazard posed by the Wasatch fault.

Riverfront Office Property

Riverfront Office Property – Screening Structure.

A screening structure once stood across the river.  This building was manned 24 hours a day.  The main road up Provo Canyon passed this site and went under the flume.

In 1952, the wooden flume was replaced with a steel pipeline.  A flow-measuring structure and sand traps were connected to the building.  Today’s automated trash-rakes at the diversion remove debris, eliminating the need for this building and 24-hour occupancy.

Dam Diversions – Dams on the Provo River.

There have been four dams that have diverted water into the Olmsted Flume and Pipeline.  The remains of one of the dams can still be seen in the river below where you now stand.  At one time, the wooden flume crossed the river here and then crossed again just downstream.
