Cut Face Creek; Cook County, Minnesota
Most of the year, Cut Face Creek doesn't have a lot of flow. During spring runoff and after a big thunderstorm, however, it can turn into a torrent. Those rare times of heavy flow expose these sandstone cut banks. Sandstone is a rare thing along the North Shore of Lake Superior where nearly all the rock is volcanic with basalt and rhyolite very common. In fact, the sandstone here is made of old rhyolite grains. You can find fossil ripple marks on loose stones. They come from beaches that vanished over a billion years ago.
