There was a bidding war and the property went under contract after just a week. Happened back in 2021... It is where they shot some scenes of the 1992 Robert Redford film 'A River Runs Through It.' 80,000 acres, which used to be property of the founder of Bank of California. Known for bull-elk and trout fishing. I'm saying this because people keep asking me. So here comes the revelation and the disclaimer. I was not one of the bidders... 

But I'll come visit. I'm assuming it's situated around Climbing Arrow Road, west of Bozeman, Montana, USA, Earth.

Just venturing a guess...
