Last week was our (almost) annual pilgrimage to Death Valley National Park in California in search of heat and dryness. March in the Valley can be fickle – cold and rainy has happened in past years – but this year didn’t disappoint. Amongst the usual tourist activities (a tour of Scotty’s Castle, a drive through Titus Canyon, and a long, bone jarring drive to the Racetrack), we got in some actual hiking. All of these hikes are at or above 3,000 feetso temperatures ranged comfortably from 50º to 75º F, usually with a mild wind. But full sun and very low humidity (8%) called for lots of sunscreen and water.
