underwater log harvesting in mn

[Terry]

Dosen't alot of the decay of submerged wood have to do with whether its sunk in the muck or exposed on the bottom. I have found wood while out mucking that was totally buried in the bottom muck and was in FINE shape, I always assumed this was due to the lack of oxygen in the muck, below the actual bottom of the lake. I found (years ago) this ice chisel made from a baseball bat, when I swam up to it only the top 16" or so of the bat handle was sticking out of the muck and thought it was just a bat until I pulled it out, dont know how long it was submerged but you can see the part buried in the muck is still like new compared to the narrow end that was exposed. I remember years ago the guys harvesting oldgrowth hardwood from the bottom of Superior said they just milled off the outer couple inches and the wood was good to go, again a rather low oxygen enviorment.
