Marmes Rockshelter, Archaeological site in Franklin County, Washington, US
The Marmes Rockshelter sits at the intersection of the Snake and Palouse Rivers, containing stratified deposits with preserved organic materials from ancient settlements.
Excavations in 1962 revealed human remains dating back 10,000 years, making it one of the earliest documented human settlements in North America.
The site contains shells, beads, spear points, and stone tools that demonstrate the advanced craftsmanship and trade networks of early Native American communities.
The rockshelter now lies submerged under Lake Herbert G. West, following the construction of the Lower Monumental Dam in 1969.
Among the discoveries was a Jefferson Peace Medal, potentially distributed during the Lewis and Clark Expedition to local Native American leaders.
