abandoned dredge found? Options

I posted this on another Colorado forum earlier.
I found a dredge up Washington gulch today just outside of crested butte exploring some new spots. Its on forestry land so i didnt think you could leave machines like that sitting out there unattended. Its about the size of a Subaru hood square...or close to that size. Bigger and heavier looking than a backpack dredge for sure.
Looked like it had been tied to the bank for a couple years now with a half rotted rope tied to a tree root. I'm surprised I hasn't washed away but its slightly high centered on a couple of large rocks just above the current. I couldn't really get out to it with the water flowing so fast and deep so I can't tell much more about it. The fittings and valves all looked to be in place.
I don't know why it would have been left out there but it was a strange find for me. I also found a fiberglass handled shovel about fifty yards downstream and there were quite a few little dig holes around like someone had a detector out there.
I don't know much about dredges but it wouldn't seem to me that someone would leave it out there sitting in he water like that.
It was missing the gas cap but the suction hose was wrapped around it and it was wired up. The nozzle was all rusted like it had just been rotting away there. Maybe it seized up and they gave up on it but as soon as the water drops I'm going back to check it out. Might be worth saving if I can pack it out of there. I couldn't imagine how they got it down there to begin with. It looks to be maybe a few years old its hard to tell but it has the sluice under it still and seems to mostly be intact. Would it be worth anything if I could get it out of there? The engine might need work but the rest of it was there I think.
What's your thoughts?
My wife found an old steel button probably from the old timers and a 5x5 elk skull and rack intact. Good day for both of us!
