About

Everyone who drives between Bozeman and Big Sky asks the same question. Now there is an app that answers it. US-191 through the Gallatin Canyon has a cellular dead zone nearly as long as the drive itself. Whatever happens in there stays invisible until somebody comes out the other end. (Same with dead zones on the Madison side) Roughly 140 crashes a year. 34 white crosses in 16 years on the approach alone. 22 miles where not even a text gets out. How's the Canyon fills that hole with the only thing that works in a dead zone: the drivers already inside it. Your phone quietly times the drive, holds the record until you have signal again, and sends it. Everyone gets to see what the canyon is actually doing. WHAT YOU GET Real drive times, measured by real drivers on the real road, not estimated by an algorithm in Seattle. Montana DOT's official surface conditions for each stretch of the drive, shown next to the newest real drive time so you can compare the two yourself. The Madison side is covered as well: MT-84, US-287 down the Madison, MT-87 over Raynolds Pass, US-20 through Island Park, and Jack Creek Road. Off until you switch them on. Weather alerts for the canyon routes specifically, not for the whole county. Driver reports pinned to recognizable landmarks like House Rock, the 35 MPH Corner, Swan Creek, the Green Bridge. Highway Patrol incidents and road work for this corridor and nothing else, written out in plain English instead of dispatch codes. While you are driving, a heads up about anything reported on the road ahead of you. A page that says where every number on the screen comes from, how fresh it is, and what none of it promises. WHAT IT ASKS OF YOU One permission tap. After that, the app anonymously notes when you pass mile markers on the corridor and shares the timing. That is your entire contribution. Every driver who does it makes the answer more accurate for everybody else. No account. No ads. No tracking. Nothing is tied to you. The app sleeps between drives so it stays out of your battery, and it pays attention only on the roads it times. You can also just open it and look. Contributing is optional, and the app tells you the same thing either way. WHAT IT COSTS Nothing, and it stays that way. "If I can prevent even one bad car accident all the effort will be worth providing this app. The more people using the app the more accurately we can gauge conditions and the more people have the right information to make safe choices, so making it free to everyone is important. Running it is not free though, so if you appreciate what this app provides your help defraying the cost will be greatly appreciated!" There is a tip jar inside if you want to help with the server bill. Nothing in the app sits behind it. Built in Big Sky by a neighbor who drives this road.

What's New in How's the Canyon?

1.1

August 14, 2026

Six more roads, and the Highway Patrol reports in plain English. THE MADISON SIDE MT-84, US-287 down the Madison valley and around Hebgen Lake, MT-87 over Raynolds Pass, US-20 through Island Park, and Jack Creek Road. All of it is off until you switch it on, under Roads shown, as a list or on a map. HIGHWAY PATROL, IN ENGLISH Incidents read like sentences now instead of dispatch codes, they say where they are more naturally ("US-191 near milepost 50"), and you only see the ones on roads you have turned on. ALSO Weather alerts now cover the Gallatin Valley approach, and have a much better level of detail all around. An About the data page that says where every number on the screen comes from. The report sheet has a Traffic button now. The wet/ice/snow button moved up to second, where your thumb already is, the rocks button covers debris too.
