Courthouse Towers - Arches National Park, UT. The rock formations in the Courthouse Towers section are the remnants of a large mesa that has been eroded by the Courthouse Wash and its tributaries. The compact collection of buttes and towers resembles a miniature Monument Valley. Some of the main formations are The Three Gossips (left of center), Sheep Rock (near center), and The Tower of Babel (right).Photo: Russ Finleyscenic, storm? Film Size 4X5
