Once all the regulations are done, cut a 4-6 foot piece and float it or drag it up on your own and take it to a local mill and see what they say. At the turn of the century deciduous trees had very little value to loggers, still to this day. However at the turn of the century those would be old growth and have much sought attributes for specialized items like guitars, violins, pianos and string bass. A large old growth deciduous tree with these specific attributes could go for as high as $100,000 per tree, higher depending on how big the tree is.
Even a old growth conifer maybe worth money, not as much but depending on how big and/or old the tree is, it could be rewarding.
A cross cut saw doesn't cost much, limber up the shoulder and good luck!!!
