Across New Mexico there are preserved ruins of ancient civilizations, as well as many locations containing petroglyphs. The closest to Ghost Ranch is Poshuouingue Ruins, however probably the most famous is Bandelier National Monument. Mesa Prieta is home to the largest number of petroglyphs (100,000+) in New Mexico. Time to brush up on some history!
Hike the hoodoos of Abiquiu. The 2.8-mile loop trail takes about an hour to walk. The Abiquiu formation consists of light-gray to yellowish gray, locally crossbedded, thin to thick beds of sandstone and siltstone. The formation is composed mostly of volcanic debris from the Latir volcanic field, which provides insight into the early development of the Rio Grande rift in northern New Mexico.
Explore any of New Meixco's Volcanoes! ~Valles Caldera~ (40 miles west-northwest of Santa Fe). This is a monument to New Mexico’s undiscovered potential. Quite simply, from the perspective of morphology, the Valles Caldera is a better example of a supervolcano than Yellowstone. It is the "poster-child" for large calderas.
