Lake Helen
Lassen Volcanic National Park California


Lake Helen is one of the snowiest places in California, maybe the country. I have seen the lake still frozen and covered with snow in late July numerous times.

The snow survey station here set a snow depth record with 331 inches (27 feet, 8.4 meters) on the ground on March 31, 1983. It is estimated that over 600 inches (50 feet, 15 meters) of snow a year fall on the southwest slopes of Mount Lassen.
