With a population of fewer than 150 people, Crestone, Colorado, is home to several world religions, including Hinduism, Zen, Catholicism, Tibetan Buddhism, and New Age, each with its own (or, in some cases, several) spiritual center. Sitting high above the town, the Crestone Ziggurat is among the most noticeable—and scenic—of the settlement’s spiritual structures. Ziggurats are large structures first built in ancient Mesopotamia out of sun-dried bricks.
