Lava Lake, Little Lava Lake, and other nearby lakes are volcanogenic, having formed after lava flows from Mount Bachelor altered drainage patterns in the area. Solidified lava flows are visible along the shorelines of both lakes, and the volcanic peaks Broken Top and South Sister can be seen to the north.
