What popular cultural celebration is associated with New Mexico’s Native American heritage?

The celebration most closely associated with New Mexico's Native American heritage is the Powwow. Powwows are culturally significant events that bring together various indigenous tribes to showcase their traditions, dance, music, and art. They serve as gatherings where Native American communities can celebrate their identity, heritage, and solidarity. The vibrant atmosphere of the powwow, featuring traditional dances and drumming, reflects the rich cultural diversity of New Mexico's Native American population.

While the Fiesta de Santa Fe and the Day of the Dead are important celebrations in New Mexico, they are more tied to Spanish and Mexican influences rather than Native American culture. Independence Day, although a significant national holiday, does not specifically highlight New Mexico’s Native American heritage. Therefore, the Powwow is the most fitting answer in the context of celebrating Native American traditions and culture in New Mexico.
