About this map

Lake Annie and the prominent Lake Annie Mtn anchor this high-desert landscape situated along the border of Oregon and California. The terrain transitions between the Fremont National Forest and Modoc National Forest, where water management is critical to the local geography. Significant water features like the Ninemile Reservoir and the drainage of N Fork Twelvemile Cr dictate the character of the land, providing vital resources for the surrounding high-elevation meadows.

Grazing and land use are evidenced by named areas like Twelvemile Meadow and Indian Meadow, connected by a network of county routes including Co RD 1 and Co RD 5. From the depths of Briggs Canyon to the distinctive peaks of Two Buttes, the map reveals a remote intersection of Lake County, Oregon, and Modoc County, California, where the natural hydrology of Big Mud Lake and Cow Head Slough defines the regional drainage patterns.
