The source goes no further than softwood here, which is a starting point rather than a specification. The species guides take the trees one at a time - what each is cut for, how it is graded, and where the line between pulpwood and sawtimber falls.
It is one of 6 facilities listed in Presque Isle County, which is where a search for a sawmill near me starts if your ground is in that county. The Presque Isle County page has every one of them side by side with what the county as a whole buys and makes, and all 302 Michigan listings run across 73 counties - which is the map that decides whether a load leaves your gate for twenty minutes or two hours.
Anybody searching for a sawmill near me needs more than one gate. If this one will not take your wood, the nearest other listings are Prells Sawmill in Hawks, 9 miles away, Mamp Sawmill in Rogers City, 9 miles away and Precision Hardwoods in Onaway, 13 miles away. Distances are straight lines between the coordinates the sources published - not road miles, and not a statement that anybody is buying.
None of this says whether the gate is open or what the load would fetch - no agency document records that. A price comes out of a sale run properly: the landowner's guide to selling timber takes the steps in the order they happen, and sealed bidding puts one tract in front of several buyers at once instead of taking the first number offered.
