Mining in East King County, Washington State

⛏ Old King County WA Mining Districts (above)
King County "Cultural Resources Protection Project, Phase 3 Volume I (2017)"

"Few places in the world present a denser growth of vegetation than does the western slope of the Cascade Mountains. In many places it is a jungle which one can see but a few rods ahead of him.

Prospecting in such a country is done under the most adverse circumstances."

- Henry Landes, WA State Geologist, 1898

II. FEDERAL - DOI Bureau of Land Management (BLM) & USDA Forest Service (FS) Mining Rules

⛏ 19 states contain federally-administered lands where one may create a mining claim. You will need a lease and significant equipment/resources to mine minerals in East King County on federal or public land. Gold panning by hand is allowed without a permit, with some restrictions (see: State)

Active U.S. Mines, all States, 2022: 489,100

⚒ 2025 Active Claims, WA: 1,832

Active Claims, King County, WA FEB 2025: 34

- The Bureau of Land Management (BLM), under the Department of the Interior (https://www.doi.gov/) manages the surface of public BLM land https://www.blm.gov/

- The U.S. Forest Service (FS), under the United States Department of Agriculture (USDA), manages the surface of National Forest System land https://www.fs.usda.gov/ (online map see https://www.fs.usda.gov/ivm/)

👉Bureau of Land Management (BLM) is responsible for the subsurface on both public and National Forest System land. Most federal land subsurface rights are already owned as public land, or retained by private parties.

🚮GOLD PANNING

👉Gold panning is allowed ✅ on FEDERAL lands near most WA 🌊State-owned Aquatic lands (rivers); Gold Panning requires a FREE permit ("Gold and Fish" (WDFW) Pamphlet)

🌊 "In-stream activities" = not generally regulated by BLM / Forest Service on Federal lands;

👉... If WA DNR requires written Hydraulic Project Approval (HPA) instead of the free pamphlet ... or ... if you conduct "highbanking" operations (above ordinary high water line), BLM requires: a Notice of Intent ... or ... Plan of Operations.

👎🚫Gold panning is not allowed on 🌲WA State Trust lands (see State section below)⛔

https://aqua.kingcounty.gov/council/clerk/OldOrdsMotions/Motion%2010379.pdf
A limited attempt at coal mining occurred at the Niblock Mine, northeast of the Scenic Area on Rattlesnake Mountain during the early years of the 1900's. Although mineral resource rights within the RMSA are held by the previous owner (Weyerhaeuser Co.), future mineral prospecting in the Scenic Area is unlikely.
