A 2024 street view driver went North on Yankee Fork Road, but not far enough to go past the dredge.
We can see part of the bucket chain above. The view below is of the back and of the conveyor that deposits the tailings.
The 988-ton dredge floated on a pond. "The dredge bucket line had seventy-two, eight cubic foot buckets and could dig to a depth of 35 feet. Eleven feet of water was required to float the dredge.....As the dredge worked, it continuously dug into its own pond in front and filled it in with tailings at the back." [

This is the screen that separates the gravel from the silt.
These are the sluice boxes.
And to feed the rock chute, rotating screen and sluice boxes, we have the bucket chain.
The bucket chain is driven by a big bull gear, a 50-to-1 drive train and 200 horsepower AC motor.

The electric motor is driven by two Ingersoll-Rand 7-cylinder 350hp diesel engines, each of which was connected to a 440v 3-phase alternator.
Looking the other way.
Several cables were needed to move the booms and the dredge.
This explains how cables moved the dredge. However, I don't think the diagram is correct. I think the stern line should slant to the left to another anchor rather than tying to the bow line.
All of the equipment is controlled from the control room.
Those levers control relays that control the motors. This photo also shows the level of detail that is explained on the self-guided tour.
So is the self-guided tour available in 2025?
This builders plate is how I learned that Busyrus-Erie made the dredge.
