"Few climbs anywhere match the heady sensation of topping out on Castleton Tower in Castle Valley. You stand alone on a sheer parapet of red Wingate sandstone, 450 feet (137 meters) tall, but as it crowns on a talus slope, you’re nearly a thousand feet (305 meters) above the desert floor and the Colorado River, your 360-degree view dominated by the LaSalle Mountains on the southwestern horizon."
