Buttes Of The Cross
Geology
Buttes of the Cross is composed of hard, fine-grained Wingate Sandstone, which is the remains of wind-borne sand dunes deposited approximately 200 million years ago in the Late Triassic. This Wingate sandstone, capped by Kayenta Formation, forms steep cliffs as it overlays softer layers of the Chinle Formation, which is exposed down to a prominent ledge formed by the Moss Back Member. Slopes below this ledge are Moenkopi Formation, down to the White Rim. Precipitation runoff drains into the nearby Green River, which in turn is part of the Colorado River drainage basin.
Climbing
The first ascent of the North Butte was made May 25, 1987, by Paul Horton and Lynn Watson via West Chimneys. The South Butte was climbed in 1994 by John Rosholt and Keen Butterworth via The Epicurean route, class 5.10c, on the north face.

Climate
Spring and fall are the most favorable seasons to visit Buttes of the Cross. According to the Köppen climate classification system, it is located in a cold semi-arid climate zone, which is defined by the coldest month having an average mean temperature below 32 °F (0 °C), and at least 50% of the total annual precipitation being received during the spring and summer. This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
