Lost Cienega (FR576) is a short connector between paved US191 and Buffalo Crossing (FR24). The first half is through heavy forest, but the road then skirts a deep depression surrounding Balke Spring, which has many snags standing and some long vistas to the south and west.
The road is gravel, but small rocks make for a bumpy drive. Shelf portions can be narrow but not sufficiently so in most places to prevent two vehicles from passing.
Camping opportunities are limited, with two sites within the first 1.5 miles in from US191. The farther in of those was among the trees, had a fire ring, and would accommodate a small trailer.
