2024 Map of Pea Ridge

About this map

The southern reaches of Phillips County are defined by the Ul Bend National Wildlife Refuge and the high ground of Pea Ridge. This modern topographic study reveals a landscape of complex drainage systems and semi-arid water management, where artificial impoundments like Shale Reservoir and Siwash Reservoir support the local environment. The terrain is characterized by a dense network of coulees, including Coburn Coulee and Hardpan Coulee, which channel seasonal runoff toward larger arteries like Fourchette Creek and Hawley Creek. Human infrastructure is sparse, limited primarily to Midale Rd and the straight lines of the Public Land Survey System, highlighting the area's conservation status. A particularly intriguing feature for geological interest is the Fish Fossil Reservoir, suggesting the paleontological potential of the region's sedimentary layers near Cottonwood Coulee.
