Organ Pipe Cactus National Monument Arizona

In Southwest Collection and Circulation.

Fascinating natural history, crystal stars, and stunning mountains all meet at this culturally and naturally diverse Arizona park. Sporadic rain-fall and extreme temperatures shape the unusual lifeforms of the Sonoran Desert. Organ Pipe Cactus National Monument preserves a portion of this desert ecosystem in a rugged wilderness of volcanic mountains and canyons, cactus-clad bajadas, mesquite-lined arroyos, and vast creosote plains.
