- Obsidian Cliff, also known as 48YE433, was an important source of lithic materials for prehistoric peoples in Yellowstone National Park near Mammoth Hot Springs, Wyoming, United States. The cliff was named by Philetus Norris, the second park superintendent in 1878. It was declared a National Historic Landmark in 1996. The cliff was formed from thick rhyolite lava flow that occurred about 180,000 years ago. The vertical columns are cooling fractures that formed as the thick lava flow cooled and crystallized. The Cliffs stands at an elevation of nearly 7,400 feet (2,300 m) above sea level and goes on for about half a mile. The cliffs also extend between 150 and 200 feet above Obsidian Creek. The flow consists of obsidian, a dark volcanic glass. The obsidian is most abundant at the base of the cliff and slowly tapers off to larger concentrations of pumice at the top. Obsidian from this site was first quarried here about 12,000 years ago. Early natives of North America placed a high value on the obsidian that came from this cliff as well as other similar obsidian deposits in the area because numerous tools could be fashioned from obsidian—most popularly, knives, spear/arrow tips, and other sharp-edged objects. In fact, obsidian from Obsidian Cliff was so sought after in early America (before the time of Columbus) that it was traded as far away as Ohio and Canada. Many studies have been done on the composition of the obsidian from Obsidian Cliff and how the obsidian from Obsidian Cliff was distributed. This research has provided evidence of the direction and extent of prehistoric trade networks. It is located about 13 miles (21 km) south of Mammoth Hot Springs, on the east side of the Mammoth-Norris section of the Grand Loop Road. The Obsidian Cliff Kiosk, just north, is also listed on the National Register. Obsidian Cliff is also located on the northern end of Beaver Lake in Yellowstone National Park. (en)
- L'Obsidian Cliff est un rempart montagneux américain situé dans le comté de Park, dans le Wyoming. Protégé au sein du parc national de Yellowstone, ce site archéologique est inscrit au Registre national des lieux historiques et classé National Historic Landmark depuis le 19 juin 1996. L'Obsidian Cliff Kiosk, un kiosque d'information lui-même inscrit à ce registre depuis le 9 juillet 1982, le présente aux visiteurs. (fr)
- 黑曜石崖（英語：Obsidian Cliff，又名48YE433）是美國黃石國家公園的一個重要的石器遺址，其歷史可追溯到180,000年前。黑曜石崖由命名於1878年。 1996年成為美國國家歷史地標。 黑曜石崖位於猛犸溫泉以南13英里（21公里）處， 其黑曜石散布方式和其成份顯示，此處可能存在著史前貿易網絡。 (zh)
