Holly Steven Sara Landscape Arch

This spring we went camping with Nathanael and Kristi and family for spring break. We first went to Goblin Valley and hiked around in the goblins. Then we camped that night near Little Wild Horse Canyon. The wind blew the tumble weeds and sand most of the night. The next night we camped along the Colorado River near Moab and Arches. The wind blew even harder there and snapped a tent pole. We went to Sand Dune Arch but had sand blown in our eyes and so made a hasty retreat. This picture is of the largest arch - originally named Delicate Arch - which was changed to Landscape Arch. How long will it hold up?
