The show has never explicitly stated why the team has never made it out to Montana. However, one Redditor has come up with a reasonable explanation as to why Montana remains unpicked. They write, “Alaska, Montana, and Wyoming make sense because of their low populations compared to the sheer size of each state.” Montana has a population of just over 1 million individuals in a land area of 147,000 square miles. That’s a lot of ground to cover, especially when you get into some of the smaller counties that don’t have as many people in it.
It’s possible the team just doesn’t feel like driving through a bunch of backroads on the off chance they’ll uncover some valuables. Of course, that doesn’t mean Wolfe and the team have ruled Big Sky Country out entirely. They could always make the trip to Billings, the most populous city in the state with around 100,000 people. There’s a much better chance there are hidden treasures in an area like that. Perhaps they’ll even dedicate an entire episode to Montana finds when they finally realize there are fortunes to be made out there.
For now, Montana is unexplored land ripe for the picking.
