Balanced Rock
        This 55-foot giant is an amazing sight from the road, and even more impressive when you get right up to it, on the short, easy trail that circles it. Like most of the arches, spires, and hoodoos in the park, it's composed of Entrada Sandstone, which has three members, or divisions. The 4-thousand pound boulder at the top of Balanced Rock is composed of the smooth and solid slick rock member, and the bottom pedestal is the wavy looking Dewey Bridge Mudstone member, which is softer and erodes more quickly. The top layer, Moab Tongue, wore away from Balanced Rock long ago, but can be seen at the top of Delicate Arch. As time passes, the Dewey Bridge Mudstone layer will erode to the point that it can no longer support the slick rock . . . and Balanced Rock will be no more.
