YOSEMITE NATIONAL PARK, Calif. — There was a time not long ago when a climb to the top of Yosemite National Park’s Half Dome was a solitary trek attempted by only the most daring adventurers.
Over the past decade, however, the route has been inundated with up to 1,200 nature lovers a day seeking to experience the iconic mountain that is stamped on the California quarter, stitched on a line of outdoor clothing and painted on the side of the park’s vehicles.
