Chelan County
This 1860s gold mining town is located on US 97, 21 miles north of Liberty in Blewett Pass. In this area there were a large number of gold mines and old mining camps. Most of the buildings were wiped out when the highway was built. There were no buildings visible in August 2009.

Blewett is located on blewett Pass about halfway between the turnoff to Liberty on Highway 97, and where Highway 97 meets Highway 2 at Peshastin. In all reality, there is little along the highway to signify that you are passing the site of the town.
