Tuna Canyon
Tuna Canyon is a short, high-angle, descending, narrow canyon in western Grand Canyon, below the North Rim. It lies across Granite Gorge in a region of four canyons, and a fifth smaller canyon, as the Colorado River courses westward around the Point Sublime (elevation, 7,192 ft), (and Grama Point (elevation, 7,692 ft)), ridgelines. The high-angle of Tuna Canyon, Tuna Creek, creates the Tuna Creek Rapids (Rapid) at the outfall. Tuna Canyon is a short canyon, nestled between the ridges, but just east is the very long drainage of Crystal Creek (Arizona), which drains from the Kaibab Plateau. The Crystal Rapid is adjacent upstream from the Tuna Creek Rapids. Tuna Canyon lies about 1.5 miles northeast of the Scorpion Ridge landform on the Colorado River. Point Sublime is directly south up-canyon about 1.5 miles, and the headwater Grama Point, traverses up-canyon, northeast, about 2.0 miles from Point Sublime, the canyon total length being more than 3.0 miles. Landforms Three major prominences and two scenic viewpoints border Tuna Canyon. The east flank is bordered by the massifs of Mencius Temple (South Tuna Canyon), connected to Confucius Temple, northeast, and connected north with Grama Point, (Northeast Tuna Canyon).(Grama Point also overlooks South Crystal
