Constructed in 1913, the Alaska Gastineau Mill was a revolutionary plant that introduced new technologies to the mining industry. Following a short ride to the site of the mill ruins, your driver sets the stage as you make your way through the rainforest and up Mount Roberts. At a display of old equipment, your guide explains the different mining methods, and you marvel at the view of Gastineau Channel far below.

Venture underground into the conveyer tunnel through which crushed ore was transported to the mill. Don hard hats and proceed along a boardwalk into the 360-foot-long tunnel. Inside, experienced miners demonstrate hard rock mining techniques and give you a feel for the mining lifestyle.

Return to the mill site, where after a brief demonstration, you can pan for gold and garnets from the tailings of the mine. Pay dirt is guaranteed and you keep what you find. Wander among displays, the ruins and the gift shop. Your driver brings you up to date on the mining industry's current role in Juneau as you return to town.
