It’s a dry heat – a boulder-studded, wind-raked Mojave heat in which rock stars lie low, artists think big, Marines train, weird plants jut toward the sun like beseeching biblical figures, and climbers cling to granite walls like insects stuck to flypaper, except the climbers are way happier. That’s a notable thing about Joshua Tree National Park and the towns around it. While legions of Californians keep their faces toward the beach no matter the season, a certain stripe of traveler is powerless to resist the desert, especially in cooler months. They come for the wide-open spaces and quirky lodgings. They come for the bands at Pappy & Harriet’s, for the steaming pools of lithium-rich water at Desert Hot Springs or for a sound bath (to be explained soon) at the Integratron in Landers.
