This report of the Mount Logan quadrangle of the Colorado Plateau is part of a cooperative U.S. Geological Survey and National Park Service project to provide geologic information of areas in or near the Grand Canyon of Arizona. Most of the Grand Canyon and parts of the adjacent plateaus are geologically mapped at the 1:500,000 scale. This map contributes detailed geologic information to a previously inadequately mapped area. The geologic information presented here will assist in future

The nearest settlement to this map area is Colorado City, Arizona, about 96 km (60 mi) north in a remote region of the Arizona Strip, northwestern Arizona (fig. 1 ). Elevations in the map area range from about 1,195 m (3,920 ft) in Whitmore Canyon (southwest corner of map) to 2,398 m (7,866 ft) at Mount Logan (northwest corner of the map). Primary vehicle access to this area is by dirt road locally known as the Mount Trumbull Road (fig. 1 ); unimproved dirt roads, such as the road to Woods Ranch in Whitmore Canyon and jeep trails, lead to various locations within the map area. Travel on the Mount Trumbull road and into Whitmore Canyon is possible with 2-wheel-drive vehicle, except during wet conditions. Four-wheel drive vehicles are recommended for all other roads and trails in the map area. Extra fuel, two spare tires, extra food and water are highly recommended when traveling in this remote area.
