Wiki Peak obsidian was used by humans as early as 13,400 cal BP. Such obsidian was recovered at the Broken Mammoth site. Such obsidian was also used at the Walker Road, Alaska, site, and Moose Creek, Alaska, site in the same area—all dating to before 13,000 cal BP.

"The Wiki Peak obsidian source is in the Nutzotin Mountains (Wrangell-St Elias National Park). An investigation of the Wiki Peak obsidian source was conducted in the past decade, and over 65 archaeological sites were recorded in a survey of the immediate area. The high concentration of sites is typical for other obsidian source areas in Alaska and northwest Canada, with few exceptions.
