I made the 2-hour drive and 2-mile hike out to explore the Canyon Sin Nombre Slot Canyon in Anza-Borrego Desert State Park, California. It was completely silent there, and I only encountered two other hikers the whole day, and otherwise had the entire place all to myself for most of the day! This was my first time exploring the canyon. I would return later to get to know the place much better, and even spend a night cowboy camping beneath the desert sky there. What an incredible place. Peaceful, silent, surreal.
