Bird watching and horseback riding are popular recreational activities in the canyon.
Artifacts of a ghost town and abandoned mining operations below a natural spring remain.
Management of the old mines is assigned to the Vernon Sheeprocks Project, a joint project managed by the United States Forest Service, the United States Department of Agriculture, the United States Department of the Interior, and the Utah Department of Natural Resources.
In a report issued in January, 2005, Harker Canyon was singled out as having the highest concentrations of heavy metals in its groundwater of any sampled area in the Sheeprock Mountains.
A natural spring can be found in the canyon at 7,400 feet (2,300 m) elevation, which flows into Harker Creek.
