The artwork is an original collaborative piece made by artist Nguyen Tran and Anderson Design Group. Balanced Rock, one of the most iconic features in Arches National Park, stands a staggering 128 feet tall. While this formation may appear to be an epic balancing act, it's not balanced at all. The slick rock boulder of Entrada Sandstone sits attached to its eroding pedestal of mudstone. Eventually, the 3,600-ton boulder will come tumbling down as the erosional process continues to shape the landscape.
