RE:Uncut log prices
Hey Max, I can help with that a little. Here are some sites quoting log prices in NB, and I know there are more. Note the prices vary by location and species, depending on what specific mills are looking for.

For the US side, I searched for "Maine log prices" and "Northeast log prices" and got a ton of hits. Most of them are for stumpage prices, not log prices, however the two should ususally trend together. With some searching you should be able to find actual log prices, even if they are for a particular mill.
