THE GREAT WHITE THRONE, Zion National Park. When the multicolored gorge that is the central feature of Zion National Park was cut deep into the Vermilion Cliffs, many temple-like masses such as the Great White Throne were carved. The cliffs are varying shades of red for the lower two-thirds, white sandstone above. And occasionally a cap of red, the remnants of still another layer not entirely eroded away, is superimposed on the startling white. Trails lead up the slopes of many of Zion's temples but nor the Great White Throne. Its majesty is viewed from the floor of Zion Canyon. (Courtesy, Union Pacific.)
