Pillar of Lost Lake
In early September I spent some time exploring central Montana. One of my stops was Lost Lake, which I only discovered by accident. As it's name implies, the lake is hard to find and information about it is scarce. Among the rolling hills north of the Highwood Mountains you would never guess there's a lake hidden away here. It's not until you walk right up to the edge of the cliffs that you can see the water. According to geologists, this lake formed during the last ice age. An ice sheet dammed up an ancient channel of the Missouri River. When the water eventually broke through the blockage, the floodwaters formed massive waterfalls over these cliffs. I was standing on top of Dry Falls, where the flow would have once exceeded that of Niagara Falls. Now the flow is only a trickle, and the water hundreds of feet below is mostly stagnant with algae at the edges. Lost Lake is located on a private ranch, but the landowner allows access if you can find it.
