Clark Fork Corridor: The Land
Imagine a rock so old and so deep, that in some places, the bottom has never been found! The mountains you have been driving through are made up of such a rock—the Prichard Formation. Dating back 1.5 billion years, it is one of the oldest exposed sedimentary rocks in western Montana. The Prichard is over 4 miles thick at the confluence of the Clark Fork and Flathead rivers and its base has yet to be discovered.HM Number | HMUE3 |
