This is the area's most authentic gold-mining attraction. The centerpiece is a 1927 gold dredge, similar to machines in Dawson City and Nome, standing five stories tall on a barge in a pond it created. When it operated, huge scoops would dig from one end, the mechanism inside would digest the gold from the gravel, and then it would dump the tailings out the back -- in this way, the pond and the dredge it supports crept 4 1/2 miles across the frozen ground north of Fairbanks. Many sterile areas you see in this area were created by these earth-eaters, because little grows on their leavings for decades afterward. Visits are self-guided, allowing you to walk through the dredge and examine museums housed in relocated gold camp buildings, showing the harsh, colorless life lived by the miners.
