Places to Go: Rainbow Park & Island Park
Visitors to the Rainbow Park and Island Park area, located on the Utah side of the monument approximately 30 miles (48 km) from the Quarry Visitor Center, can discover some of Dinosaur's most scenic geology, watch river rafters float past the Green River (or, with a little advance planning, be one of those river rafters), and explore petroglyphs and a historic ranch, both part of the monument's long human history. Picnicking and camping are also available in the area.
Visiting the areas described below requires driving on unpaved roads. These roads are impassable when wet. Before heading to the Rainbow Park and Island Park area, stop at the visitor center for information on road conditions.
A map of the Rainbow Park and Island Park area can be found here.
The Fremont people, who lived in this area approximately a thousand years ago, left evidence of their presence in petroglyphs (patterns chipped or carved into the rock) and pictographs (patterns painted on the rock).
Petroglyph panels at McKee Springs include some of the finest large human-like designs in the Dinosaur area, as well as many other figures. The petroglyphs are a short walk from the roadside pullout.
In 1882, Henry and May Ruple began homesteading in Island Park and developed a cattle ranch. The Ruples' son, Hod, took over the property in 1915. Later, Hod Ruple and his family switched from cattle ranching to sheep ranching. The property remained in the Ruple family until 1945.
Although the family's original house burned in 1960, the corrals and loafing shed found on the site today were used in the Ruples' ranching operations.
