Grizzly Gulch - Helena
By driving up Helena's Last Chance Gulch, you arrive at Grizzly Gulch, lined by old diggings. Four miles beyond is Unionville, around which are several old gold mines, including the Spring Hill and Whitlatch Union. Ruins of old stamp and flotation mills loom over the gulch and foundations of old homes are visible.
Up to 1869 the approximate aggregate yield of the placers in Grizzly Gulch was $5,000,000.
