Malgosa Crest

Malgosa Crest is a 5,446-foot-elevation summit located in the eastern Grand Canyon, in Coconino County of northern Arizona, US. The ridgeline-crest is situated adjacent to the East Rim, being a middle, and minor prominence, (of three major prominences), along the Butte Fault. From south to north, and bordering the due-south flowing Colorado River (west bank), are Chuar Butte, Awatubi Crest, Kwagunt Butte, Malgosa Crest, and the Nankoweap Mesa. All the prominences are near the end of Marble Canyon, (down to the Little Colorado River confluence), Marble Canyon being the start of the Grand Canyon. Malgosa Crest has a very narrow, linear platform prominence, and the prominence is deeply eroded, and it trends slightly southwest–northeast. Because of its narrowness, its ridgeline-summit is composed of eroded remainder cliffs of cliff-formed Coconino Sandstone (on slope-formed Hermit Shale), both surviving on a resistant platform of the 4th member of the Supai Group – the resistant, cliff-former Esplanade Sandstone. (The sandstone forms The Esplanade in Western Grand Canyon, a horizontal hiking area.) The high point of Malgosa Crest is at the center of the ridgeline (5,446 ft); a surviving lower elevation, but highly visible, caprock peak occupies the northeast end of the ridgeline (5,242 ft).
