Treadwell gold mine

The Treadwell gold mine was on the south side of Douglas Island,.5-mile (0.80 km) east of downtown Douglas and southeast of downtown Juneau, owned and operated by John Treadwell. Composed of four sub-sites, Treadwell was in its time the largest hard rock gold mine in the world, employing over 2,000 people. Between 1881 and 1922, over 3 million troy ounces of gold were extracted. Not much remains today except for a few crumbling buildings and a "glory hole". Although John Treadwell had twelve years of experience in both placer and lode mines, he was a carpenter and builder by trade who had come to Alaska prior to the Klondike Gold Rush.
