This GeoSNAPs image of a debris-flow clogged drainage channel in the Huachuca Mountains of SE Arizona. Heavy monsoon rains can produce voluminous and dangerous debris-flows in Arizona's Sky Iland mountains. Add wildfire destruction of foliage and soil damage and the picture gets starker. This debris-flow spilled onto a roadway in the Coronado National Forest. Clearing the road of debris resulted in this view.
