The area is a largely arid desert with a few shrubs and cactus. Most of the land is too arid and dry for farming, making cattle ranching a more preferable choice. Crime – particularly in the form of outlaw gangs – is prevalent, and so danger is common. The region consists of wide-open desert plains and low lying hills with small rocky canyons and cliffs with jagged peaks. Trees are almost non-existent. The largest source of water in the region is Lake Don Julio to the south.
Its capital is the town of Armadillo; once a small and diseased village in the 1890s, it has grown to be the largest and most well-known location in the entire state of New Austin by 1911. Aside from Armadillo, the county is mostly rural, littered with a few small ranches and a train station.
