Tucked-away in Oregon’s Willamette National Forest is a lake with waters as clear as a swimming pool and fascinating wonders hiding underneath.

Oregon’s Clear Lake is a spring-fed lake that was formed around 3,000 years ago through lava flows that ran from Sand Mountain, creating a natural dam that slowly filled with water over the years.

The forests that surrounded the lake were submerged into the water overtime, remaining today in the form of trunks that can extend as far as 120 feet into the water.

Thanks to volcanic activity that once shook the area, the lake's grounds are also covered with volcanic silt that is so thick, it looks like white sand.

This, in combination with the shipwrecks of wooden boats — some of which date back to the 1920s — sitting on the white silt, makes it feel as though you're diving through an underwater beach.
