Zion National Park, Washington County, Utah. Photo by Marshall Robinson.
Beautiful hanging gardens decorate an alcove in Jurassic-age Navajo Sandstone along the Riverside Walk trail at the mouth of The Narrows in Zion National Park. Rainwater seeps down through porous sandstone until it flows laterally along a less-porous rock layer, ultimately trickling out of the canyon wall.
