Chuar Butte and adjacent Temple Butte are the historical site of wreckage from the 1956 Grand Canyon mid-air collision, in which two commercial airliners collided, resulting in the deaths of all 128 on board both planes. This disaster was a catalyst that forced the government to overhaul airline regulation and to establish the Federal Aviation Administration. The site was designated a National Historic Landmark on April 22, 2014, and is in a remote area of the canyon that is only accessible to hikers.
Geology
The top of Chuar Butte is composed of PermianKaibab Limestone, which overlays cream-colored, cliff-forming, Permian Coconino Sandstone.[7] The sandstone, which is the third-youngest of the strata in the Grand Canyon, was deposited 265 million years ago as sand dunes. Below the Coconino Sandstone is reddish, slope-forming, Permian Hermit Formation, which in turn overlays the Pennsylvanian-Permian Supai Group. Further down are strata of MississippianRedwall Limestone, and finally CambrianTonto Group at river level. The Butte Fault is on the west side of Chuar Butte. Uplift along the fault has lifted the NeoproterozoicChuar Group 3,000 feet relative to the limestone layer, exposing mudstone of the Chuar Group.[8]
