Thompson Flat sits at the heart of this backcountry landscape, where the high-altitude terrain is defined by a network of seasonal camps and water sources. The map reveals a remote working landscape used for livestock and forestry, centered on established points like the Thompson Corral and Juniper Camp. Drainage systems like Matlock Creek and Gilbert Creek carve through the plateau, leading toward notable landmarks such as Thompson Falls. Human presence is sparse but specific, marked by Florence Cabin and the Matlock Water Hole Camp. The intricate forest road system, including the Potamus Lookout Rd and Penland Prairie Rd, provides the primary access across these ridges, connecting remote overlooks like Potamus Point and the high vantage of Zion Scope.
