About this map

Obsidian Cliff stands as a prominent volcanic landmark within Yellowstone National Park, anchoring a landscape defined by thermal activity and high-elevation terrain. The road network, primarily the Grand Loop Rd, connects several hydrothermal features such as the Semi-Centennial Geyser and Roaring Mtn. The hydrology of the area is complex, with numerous named springs like Frying Pan Spring and Apollinaris Spring feeding into drainages such as Obsidian Cr and Solfatara Cr.

Wilderness access is documented through established routes including the Solfatara Creek Trail and the Mount Holmes-Winter Creek Trail, which provide passage through the high-country basins. Notable water bodies such as Lake of the Woods and the thermal Porcelain Basin reflect the unique geological character of this corner of Park County. This map details a region where the natural hydrothermal system dictates the placement of backcountry infrastructure and scenic overlooks.
