El Morro National Monument, Ramah, NM

The monument’s sandstone bluff sits along a busy trail, and for centuries explorers and passersby carved inscriptions into its walls. You can trace the history of New Mexico through these carvings, which include Native American petroglyphs, ornate writings by early-17th-century Spanish explorers, and the signatures of 19th-century American soldiers. The mesa top is notable for its geologic formations and Indian ruins.
