(Brian Witte | AP) In this May 28, 2013 file photo, a hiker walks on a rock formation known as The Wave in the Vermilion Cliffs National Monument in Arizona. A walk-in lottery for the popular Arizona hike could move online. Half of the 20 permits for one of the most exclusive and dramatic hiking spots in the southwestern United States remain unavailable during the coronavirus pandemic. The virus hasn't forced the closure of the Wave in the Vermillion Cliffs National Monument along the Arizona-Utah border. But it has suspended a daily, in-person lottery for 10 permits because the agency that oversees it can't ensure social distancing.
