Frey Hills

The Frey Hills are a small, isolated mountain range located in the north-central region of North Dakota. Rising abruptly from the surrounding plains, these hills feature gentle, rolling terrain with scattered tree-covered slopes and exposed rock outcrops. Elevations range from around 1,800 feet in the foothills up to the highest point at 2,420 feet. The hills were formed by ancient glacial processes and are composed primarily of sedimentary rock. Vegetation is dominated by hardy grasses, shrubs, and a mix of coniferous and deciduous trees.
