About this map

Blackjack Ridge and Buffalo Wallow Mtn dominate this portion of the Ouachita Mountains in LeFlore County. The landscape is defined by its deep drainages and named hollows, including Negro Hollow, Conley Hollow, and the aptly named Hells Hollow. These features reflect a rugged topography where water sources like Cedar Cr and Birney Cr carve through the sandstone and shale layers typical of the region.

Modern infrastructure follows the path of least resistance through these landforms, with Us HWY 271 and Holson Valley Rd providing the primary transit corridors. A significant local landmark is the Flying Ranch Number 1 Reservoir, located near the headwaters of Little Buzzard Cr. The map also captures the transition from steep peaks like Rattlesnake Mtn to the higher, level ground of Boardstand Flat, illustrating the diverse elevation patterns of this Oklahoma highland area.
