The story

How Marblemount came to be

From Wikipedia’s history of Marblemount.

Read it all →

Present-day Marblemount was the site of an indigenous village when naturalist George Gibbs explored the region in 1858. A community of Euro-Americans arose in the 1870s to supply goods for miners along the Skagit and Cascade River drainages. A wagon road was built between Marblemount and Sauk in 1892.
