view of colorado river from tuweep

The stunning view from Toroweap Overlook can only be reached by negotiating difficult roads.

At 3,000 vertical feet (880 m) above the Colorado River, the sheer drop from Toroweap Overlook offers a dramatic view. The volcanic cinder cones and lava flows in this ancestral home of the Southern Paiute people make this area unique.

A visit to Tuweep provides an opportunity for an uncrowded, rustic, and remote experience. Access is challenging and demands skill at negotiating difficult roadways.

Services are non-existent: there is no water, gas, food, lodging, or phone service.

Access the three main routes to Tuweep from AZ 389 between Fredonia, Arizona, and St.George, Utah. Allow two to three hours driving time. Bring the BLM Arizona Strip Visitor Map, and do not rely solely on your GPS unit. Muddy conditions exist during summer monsoons and from winter precipitation.

Sunshine Route: County Road #109, the most reliable route, leaves AZ 389 eight miles (13 km) west of Fredonia or six miles (10 km) east of Pipe Spring National Monument. This 61-mile (98 km) road features sharp rocks, washboarding, and dust. Please do not stop on tribal land when traveling this route.

Clayhole Route: County Road #5 leaves AZ 389 at Colorado City, Arizona. It is 56 miles (90 km)
long and impassable when wet.

Main Street Route: BLM Road #1069 and County Road #5 from St. George is 90 miles (145 km) long. This scenic route is impassable in winter due to snow and mud.

Tuweep Airstrip: Closed.

Tuweep Trails

Tuweep’s hiking trails are marked with cairns (piles of rocks). Shade and water are scarce, and water non-existent. Walk only on trails, roads and washes. Each footstep off trail may destroy fragile biological soil crusts and damage native plants. All trails are CLOSED to PETS, BICYCLES, and VEHICLES.

Tuckup Trail:

Experience Tuweep's unique geology on this six-mile (10 km) roundtrip trail. There are two access points: the first is signed before arriving at Tuweep Campground and the second leaves from campsite 10.

Saddle Horse Loop Trail:

This 45-minute loop offers spectacular views of the Colorado River. Access the trail along the road between Toroweap Overlook and Tuweep Campground or from a trailhead near campsite 5.

Trail to Access the Colorado River?
Please visit the Whitmore Trail, located at Whitmore Overlook, a 3 hour drive west of Tuweep, this moderate four-mile (6.5 km) roundtrip trail takes you down to the Colorado River. Access Whitmore Overlook from the Main Street Route; high clearance needed.

Geology

The geologic history of the Tuweep area is similar to the rest of Grand Canyon, but includes a more recent chapter of volcanism. The Toroweap Fault underlies the valley, crosses the Colorado River, and continues south up Prospect Canyon. Volcanic activity began along this fault around seven million years ago. Over time, lava issued from more than 60 vents. Beginning about 1.2 million years ago, lava flowed into Toroweap Valley, forming the flat-bottomed valley we see today. Vulcan’s Throne, Mount Trumbull and the Uinkaret Mountains are all the result of volcanic activity.

More than a dozen times, lava spilled over the canyon rim, damming the Colorado River. Remnants of these flows and dams are visible just west of the overlook. Sediments clinging to the canyon walls high above the river indicate the formation of large lakes. The river eroded the lava dams and continued its downward cutting. It is now 50ft/15m deeper than the base of the dams. Despite its name, Lava Falls Rapid was formed from debris washed down Prospect Canyon, not from remains of the lava flows.

It is less than one mile across the canyon to the Hualapai Indian Reservation on the South Rim, making this one of the narrowest and deepest segments of the inner canyon. The colorful red-rock of the Hermit Shale and Supai sandstones to the east contrasts with the black, basaltic lava flows to the west.

Ecology

Tuweep sits at an elevation of 4500ft /1400m on a landform known as the Esplanade which forms a flat shelf situated about halfway between the coniferous forests of the North Rim and the hot canyon bottom. This is a high desert area with mild winters and light snows. Summers are hot with thunderstorms from July to September.

In Toroweap Valley a chaparral community exists with juniper and pinyon pines, sagebrush and saltbush, Mormon tea and other woody shrubs, and various grasses. Near the Esplanade, succulent cacti, yucca, and agave predominate. In years of abundant winter moisture, wildflowers proliferate. Some life forms, like the crusty black biological soil crust, are rare and sensitive. Please avoid stepping on these fragile living organisms!

Wildlife includes coyotes, mule deer, jackrabbits, rodents, and numerous species of birds and reptiles. An often-overlooked and little-understood biotic community exists seasonally in the slick-rock potholes on the Esplanade. Fairy and horseshoe shrimp, tiny frogs, and microscopic organisms emerge from the muddy bottom when moisture fills these pools.

Human History

Toroweap, a Paiute term meaning "dry or barren valley," refers to local features, including the valley and the overlook. Tuweep came into use to describe the local white settlement and later the park area. Tuweep in Paiute (pronounced Tu-VEEP) refers to "the earth”.

The first humans in the Tuweep region were ice-age hunters who lived a nomadic hunting-gathering existence in what was a milder climate. The Ancestral Puebloans, arriving about 2000 years ago, farmed in this area. They migrated eastward around A.D.1300. The most recent native Americans living here were the Paiute. They now live to the north.

John Wesley Powell, led by a Paiute guide, visited Tuweep in 1870. He mapped and named many of the local features. More recently, European-Americans ranched, mined, and settled in the area. While ranchers used this valley seasonally in the early 1900s, the first year-round homestead was the Lower Kent Ranch, built in 1927, located just north of the park. Other pioneers in the region included the Schmutz, Cunningham, Craig, and Bundy families. Henry Covington herded sheep and mined on the Esplanade for over 20 years. There are still many sites that speak of his determination to live and prosper in this arid region.
