This snout is several miles upstream from the confluence of Rattlesnake and Sabino Creeks, and the large boulders are typical of the largest particles transported during debris flows in the southern Santa Catalina Mountains. Most of these boulders likely were transported from debris-flow initiation zones, although some may have been entrained from the bed of Rattlesnake Creek.
