Zion National Park is a United States National Park located near Springdale, Utah in the southwestern United States. The principal feature in the 229 square mile (593 km²) park is the 15 mile (24 km) long and up to half a mile (1 km) deep Zion Canyon, which was cut through the reddish and tan-colored Navajo Sandstone by the North Fork of the Virgin River. The geology of the Zion and Kolob canyons area includes nine formations that together represent 150 million years of mostly Mesozoic-aged sedimentation. At various periods in that time, warm, shallow seas, streams, ponds and lakes, vast deserts and dry near-shore environments covered the area. |
