I visited Joshua Tree Nat’l Park last week for the first time. With 794,000 acres of “moonscape,” the park sits on the flyway to and from Los Angeles. Only 140 miles separate the two. The geography beckons hikers, rock climbers, birdwatchers, photographers, stargazers, and of course, the curious. The Mojave Desert covers the western half with elevations above 3,000 feet. Where mega boulders stand atop one another. Where the slow-growing Joshua tree lives into old age. Where rapellers get an adrenalin rush. And, where travelers like me are wowed by the vistas.
