The prominent feature of the Zion National Park is Zion Canyon, which is 24km long and up to 800m deep, cut through the reddish and tan-colored Navajo Sandstone by the North Fork of the Virgin River. Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park's unique geography and variety of life zones allow for unusual plant and animal diversity. The river was the largest force in cutting the canyon, mostly by flash floods, as the average flow of the river is very light.
The beginning of the canyon is delineated as the Temple of Sinawava, a vertical-walled natural amphitheater nearly 910m deep. The canyon actually begins much further upstream, and runs about 26km through the Narrows to reach the Temple. While the canyon rim is dominated by desert, the canyon floor supports a forest and riparian zone watered by the North Fork Virgin River. The canyon's end is where it meets the Virgin River, some 160km northeast of Lake Mead.
About the stamps
About the stamp featuring a portrait of George Washington, I wrote here. About the stamp depicting the iconic figure of "Wisdom" which is installed over the entrance to the GE Building at Rockefeller Center, I wrote here. The other stamps are part of the series Modern Art in America: 1913-1931, about which I wrote here.
