State and federal timberland around central Montana could bring in less money as the price for transporting logs increases, a trend that has been growing as fewer mills operate near the state’s expansive forests. Timber sales around Seeley Lake could drop the most. Pyramid Mountain Lumber, the town’s mill, plans to close next month unless a new buyer helps the business stay open. Pyramid General Manager Todd Johnson told the Missoulian on Friday that one group has made a proposal to keep the company in business, and a couple more investors still have interest as well. Johnson said Pyramid Mountain Lumber is reviewing all the interested groups, but will not make a final decision until the May 15 deadline to find a buyer. The mill has some wiggle room for a couple weeks after that date in case of last-minute changes to proposals.
