No species line was published for this address, so what it will and will not take is a question for the mill itself. The species guides are the other half of that conversation: what you are holding, and what it is normally worth.
It is the only facility the Wyoming sources list in Carbon County, which is worth knowing before you plan a haul: the next gate is in another county. The Carbon County section of the state page shows it standing alone, and all 30 Wyoming listings cover 12 counties.
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 Powers Logging in Douglas, 114 miles away, Wind River Supply - Sawmill in Kinnear, 150 miles away and Great Divide Forestry in Worland, 182 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.
