The oldest known human habitation in the area dates to about 7,000 years ago, and by about 5,000 years ago, there was substantial human habitation in the surrounding area.[citation needed]At the time of Euro-American contact in the 1820s, the Native American tribes who lived within view of Mount Shasta included the Shasta, Okwanuchu, Modoc, Achomawi, Atsugewi, Karuk, Klamath, Wintu, and Yana tribes.The historic eruption of Mount Shasta in 1786 may have been observed by Lapérouse, but this is disputed. Although perhaps first seen by Spanish explorers, the first reliably reported land sighting of Mount Shasta by a European or American was by Peter Skene Ogden (a leader of a Hudson's Bay Company trapping brigade) in 1826. In 1827, the name "Sasty" or "Sastise" was given to nearby Mount McLoughlin by Ogden.[14] The name was transferred to present-day Mount Shasta in 1841, partly as a result of work by the United States Exploring Expedition.
