August 31, 2024, Lake Helen

Lake Helen is a glacial tarn situated at approximately 8,200 feet in Lassen Volcanic National Park, in Northern California. Located south of Lassen Peak and west of Bumpass Mountain, the lake lies along Highway 89 and is visible from the road. Named after Helen Tanner Brodt, the first white woman to summit Lassen Peak in 1864, it remains frozen and snow-covered for most of the year due to its high elevation.
