Brickyard Arroyo

(32.047589, -110.953288)

Arroyos are steep-sided gullies that form in deep sediments. Arizona, New Mexico, and California are particularly susceptible to arroyos. We will visit an arroyo called Brickyard, just south of Tucson in the middle Santa Cruz River basin. We'll see deep sediments with changing textures and colors, and artifacts.
