Silver Canyon takes place in modern day San Juan County, just east of the Colorado River, in what is today the Glen Canyon National Recreation Area and the Canyon Rims Recreation Area, not many miles upstream from Hite, Utah, which is mentioned in the story. The plot revolves around a young rider and gunfighter, Matt Brennan, who drifts into the town of Hattan's Point and immediately falls in love with a local rancher's daughter, Moira Maclaren. The town and the area around it are dominated by two large ranches, the Boxed M owned by Rud Maclaren, Moira's father, and the CP Ranch owned by the Pinder brothers. With a reason to stay in the area, Brennan buys into the Two-Bar Ranch, owned by old man Ball. The Two-Bar is sandwiched between the Pinder and Maclaren Ranches, and being squeezed out, as the two bigger ranches prepare for their showdown with each other.
L'Amour demonstrates his intimate knowledge of the terrain and the West in general, and you can today almost ride (or hike) to the same locations in which the events of the story took place. Some of the key features:
Hattan's Point, both the mesa and the town, are located on what is today called Middle Point, approximately 12 miles east and 5 north of Hite, above Cataract Canyon on the Colorado River. The Boxed M Ranch headquarters was located just north of Bowdie Canyon (Cottonwood Wash in the story) on Bowdie Point, northeast of Hattan's Point. The Pinder Ranch was headquartered on modern Lean-To Point on the edge of Dark Canyon Primitive Area. Two-Bar Canyon is a branch off the north side of Bowdie Canyon, both of which drain Dark Canyon Plateau which rises to the summit of the Sweet Alice Hills. Located almost due west of Monticello, Utah, access to the area is difficult, requiring use of a series of backcountry trails over the Abajo (Blue) Mountains or off State Route 211 near Newspaper Rock, or by boat and foot/horseback northeast from Hite Marina on the upper end of Lake Powell. The terrain can be as deadly today as it was in the 1880s.
