Along Gastineau Channel across from downtown Juneau, the resilient alder trees grow, a sign that the earth was disrupted here years ago. If you look more closely, you will see rubble, rusted over pieces, and the ruins of a world now crumbling in the forest. Treadwell Historic Trail runs along Gastineau Channel across from downtown Juneau and the ruins of this incredible historic mine tell a tale of industry, civilization, disaster and abandonment. It’s mind blowing to think that these bits of antique machinery were once part of the largest gold mine in the world! Visit the Treadwell Historic Trail to see the site of a giant of industry from Alaska’s past.
