Signal Butte, Archaeological site in Scotts Bluff County, US.
Signal Butte rises 120 feet above the North Platte River watershed, containing three distinct layers of prehistoric cultural materials under gravel and soil.
The site drew national attention in 1931 when Thomas L. Green discovered ancient tools, leading to excavations by William Duncan Strong in 1931 and 1932.
The archaeological layers reveal 5,000 years of Native American presence, including storage pits, stone projectile points, drills, bone tools, and pottery fragments.
Located on private property in western Nebraska, visitors can only observe Signal Butte from designated viewpoints following specific routes from Gering.
Signal Butte holds designation 25SF1 from the Smithsonian Institution as one of the first investigated pre-contact Native American sites in the central plains.
