One of the best rock art sites in all of Utah is found in an otherwise nondescript canyon a few miles northwest of Vernal in the northeast corner of the state, on private land of the McConkie Ranch, a homestead established early in the 20th century by Virt and Caroline McConkie. The McConkie Ranch Petroglyphs span nearly a mile, at the base of low, southwest-facing cliffs that border the wide, shallow canyon of Dry Fork Creek, a tributary of Ashley Creek, and they include dozens of panels, many with unusually complex designs, created over the course of several centuries, with some of the more detailed figures etched on top of older, simpler designs. The majority are thought to have been made before 1200 AD.
This area lies just within the northern edge of the Colorado Plateau; the yellowish-brown rocks in the cliffs are from the Bell Springs Formation and the Nugget Sandstone, strata replaced by the Navajo Sandstone further south on the plateau.
Although part of a private ranch, the owners, grandchildren of Virt and Caroline, allow full public access on payment of a small fee, and provide trailhead parking with some basic facilities. All can be seen in one to two hours, by two short hikes, northwest and southeast of the parking place.

Introduction
The petroglyphs include features common to many other rock art sites including geometric shapes, anthromorphs and animals, though the site is famous for its more dramatic images, that appear to depicts acts of violence such as severed heads and other body parts, warriors carrying weapons, and figures with red pigment signifying blood. There seems to be no generally accepted theory as to the precise meaning of these images, however.
The majority of the designs are representative of the Classic Vernal Style, one characteristic element being anthromorphic figures based on an inverse triangular shape, wide at the top, at the shoulders, narrowing below, at the waist. The majority were made by people from the Fremont Culture, who inhabited a large region either side of what is now the Utah-Colorado border, adjoining the Sevier peoples to the west and the Anasazi, or Ancestral Puebloans to the south.
Location
The McConkie Ranch trailhead parking is ten miles from Vernal city center, driving west along Hwy 121, north on 3500 W, northeast on Dry Fork Settlement Road and finally north on the (still paved) McConkie Road, which crosses Dry Fork Creek, and also leads to the ranch, in which there is a small museum containing artefacts found in the vicinity.
