TONTO NATIONAL FOREST, Ariz. (AZFamily/Gray News) — An Arizona man is accused of living illegally in the Tonto National Forest for years and accumulating about a half-ton of trash at a campsite in what a U.S. Forest Service officer described as one of the “worst residential cases” seen. Mark Aaron Gatz was arrested last month and faces multiple counts, including living on forest grounds and lighting a fire during Stage 2 restrictions, according to court documents.
