The Willamette Meteorite, officially named Willamette and originally known as Tomanowos by the Clackamas Chinook[4][5] Native American tribe is an iron-nickel meteorite found in the U.S. state of Oregon. It is the largest meteorite found in North America and the sixth largest in the world.[6][7] There was no impact crater at the discovery site; researchers believe the meteorite landed in what is now Canada or Montana, and was transported as a glacial erratic to the Willamette Valley during the Missoula Floods at the end of the last Ice Age (~13,000 years ago).[8] It has long been held sacred by indigenous peoples of the Willamette Valley, including the federally recognized Confederated Tribes of the Grand Ronde Community of Oregon (CTGRC).
