The Abó Unit of Salinas Pueblo Missions National Monument, located west of Mountainair, New Mexico, spans approximately 370 acres and showcases a rich history dating back to around 800 AD. The site was initially occupied by the Pueblo people, who built rectangular red sandstone masonry pueblos and engaged in farming, hunting, and trading. When the Spanish arrived in 1581, they found a thriving community. The mission of San Gregorio de Abó was established in 1622, with the first church completed by 1626. Due to a growing population, a larger church was built by 1651, the remnants of which can still be seen today. Abó was abandoned in 1673 due to disease, drought, famine, and Apache raids, but Spanish settlers briefly returned in the 1800s. Visitors to Abó can explore the .75-mile interpretive loop trail through the 17th-century mission ruins, photograph 1820s Spanish resettlement structures, enjoy the natural surroundings, picnic in the designated area, and participate in ranger-led programs and special events. The site offers a unique glimpse into the region's history and cultural heritage.
