Isaac Swim Lost Yankee Fork Quartz

Lost Treasure ID • Custer County County
Description
1881 Salmon River country legend of Isaac T. Swim drowning in spring runoff with the sole knowledge of rich gold-bearing quartz near the mouth of the Yankee Fork — partners found a claim marker but never the ledge.
Historical Notes
Swim filed on gold quartz near the Yankee Fork mouth in 1881, returned for samples in fall, and died crossing the flooded Salmon the following June while leading impatient partners. Searchers found his drowned horse downstream and later a claim marker across the river from the Yankee Fork mouth, but the bonanza quartz was never relocated. The tale is a classic "lost mine" story of the central Idaho mineral belt near present-day Challis country.
Status / Verification legend — Legendary or approximate
