Jew Mountain sits in rugged country on the BItterroot National Forest east of Painted Rocks Reservoir. One listener was curious about how the mountain got its name. The search for an answer revealed some family ties, a slice of history and a deeper story about geography, genealogy and why words matter.

Have you had any unexpected bird sightings this winter? Maybe you saw birds in unexpected places or times. Or maybe birds you expected never showed up. You're not alone. Bird researchers – and an observant listener – have noticed, too. That listener wants to know: What do we know about how climate change is impacting birds, both in and out of Montana?

"Harmonic rippling pattern" might seem like a description of the soothing sounds from a white-noise generator lulling you to sleep. That's close. But in this case, the noise machine is your car and the rippling pattern is the washboard road you're bouncing over. One listener wants to know what causes these washboard patterns.

Pencils down! Does that phrase bring back some anxiety-inducing memories? What if, like in your bad dreams, it's an exam you haven't studied for? A listener wants to know why student test scores have stopped rising. The answer involves triangles and time. Learn more in this lesson of The Big Why. There won't be a quiz afterward.

Elk are a familiar sight in much of Montana now, but that hasn't always been the case. By the early 1900s, unregulated hunting had led to massive declines in wildlife nationwide. But In Yellowstone, elk populations were exploding thanks to protections in place there. The solution to restoring elk outside the park seemed obvious. Less obvious was how to make it happen. This week on the Big Why, we trace the animals' bumpy path from the living laboratory called Yellowstone Park to the Bitterroot Valley and beyond.

If you’ve been to a taproom, you know that at most breweries across the state there’s a three pint limit and they stop serving at 8 p.m. One listener wants to know why. We've got answers.

When it comes to winter driving, everyone wants their route clear and dry, and they want it done quickly. Why don't the plows come sooner or more often? Why don't they drop more salt or deicer? Why not get more drivers on the road? Tag along as a Montana snowplow driver prepares for a big winter storm and find out more about the logistical, environmental and technical challenges that come with keeping the roads clear of snow.

How do cabbage and spices become ingredients for community building? In Korea, the answer is kimjang, the fall tradition of making and sharing kimchi. This week on The Big Why, we visit a farm in the Bitterroot Valley where a group of Montanans came together to keep a food custom alive and find comfort and connection among the cabbage.

In Montana, abortion access has been at times illegal, legal, and stuck in limbo. Providers have weathered bombings and arson, advocates and opponents have battled it out in court, and citizens have passed a constitutional amendment affirming a woman's right to choose. One listener wants to know more about the history of reproductive rights in Montana. MTPR's Aaron Bolton reports on the underground networks, political violence and landmark court cases that got us to where we are today.

A flag's primary purpose is to be recognized from a distance. That means few colors, no lettering and a clear distinction from other flags. Ideally, it should be simple enough for a child to draw it from memory. So, how did Montana end up with such a complicated flag? Learn more in this episode of The Big Why.
