About this map

Yellowstone National Park encompasses this high-elevation wilderness where the Lamar River meets its major tributaries. The landscape is dominated by the broad Lamar Valley and the steep slopes of the Absaroka Range, with Amethyst Mtn rising significantly in the western portion of the quadrangle. This area serves as a critical junction for backcountry travel, as evidenced by the network of historical paths including the Specimen Ridge Trl and the Lamar River Trl.

Hydrographic details reveal a complex drainage system where Soda Butte Creek flows through the prominent Soda Butte Canyon to join the main river. Smaller waterways like Chalcedony Cr, Cache Creek, and Opal Cr carve through the mountain terrain. Human infrastructure is limited to the NE Entrance Road in the north, leaving the vast majority of the sheet to document the undisturbed natural topography and drainage patterns of the park's interior.
