About this map

Obsidian Cliff stands as the central landmark of this high-elevation terrain within Yellowstone National Park. The map documents a landscape defined by its thermal activity and volcanic geology, from the steam and mineral deposits of Porcelain Basin to the thermal features at Roaring Mtn. Modern travel follows the Grand Loop Road - Mammoth-Norris, tracing a route past the high-silica glass formations of Obsidian Canyon.

The area is saturated with distinctive hydrological features, including Semi-Centennial Geyser, Lemonade Lake, and the remote Lake of the Woods. These water bodies and springs, such as Amphitheater Springs and Whiterock Springs, illustrate the complex geothermal plumbing of the region. Backcountry access is noted via the Solfatara Creek Trl, which winds through the eastern portion of the quadrangle near Horseshoe Hill.
