Our map of America’s federal public lands (March 2018, page 10) accidentally swapped New Hampshire and Vermont. Our apologies to all the Vermonters who were excited to finally have a coastline. In a November article about winter hikes (“Better in Winter,” page 40) we called Colorado’s Big Dominguez Canyon “a classic three-day, 35-mile route.” Ryan Staude wrote in with a field report. “The last 17 miles down [the Little Dominguez Creek Trail] is currently a heinous bushwhack with more complicated routefinding than one might expect,” he said. “We ended up having to find a different route out of the canyon.” His suggestion for an easy winter hike: a two-day out-and-back on the Big Dominguez Trail. In a March story about Canyon de Chelly (“In the Right Hands,” page 74), we stated that visitors can only tour the canyon bottom with a Navajo guide. One path, the 1.3mile White House Ruins Trail, is open to unguided hikers.
