If you aren’t aware of the visual pageantry found in the American Southwest’s dramatic river canyons and rock formations, then you’ve been living under, well, a rock. The region is as storied as it is scenic. A bit of lore and learning can enhance the visual feast and make touring these epic landscapes that much richer. So scoot over, armchair geologists, and make room for archaeologists and anthropologists on the Trail of the Ancients Scenic Drive, a 480-mile route through Utah and Colorado.
