Mount Lassen NP

8. Small Valley

Since the entire park is located at medium to high elevations, the park generally has cool-cold winters and warm summers below 7,500 feet (2,300 m). Above this elevation, the climate is harsh and cold, with cool summer temperatures. Precipitation within the park is high to very high due to a lack of a rain shadow from the Coast Ranges. The park gets more precipitation than anywhere else in the Cascades south of the Three Sisters. Snowfall at the new visitor center near the southwest entrance at 6,700 feet (2,040 m) is around 430 inches (1,100 cm) despite facing east. Up around Lake Helen, at 8,200 feet (2,500 m) the snowfall is around 600-700 inches (1,500-1,800 cm), making it probably the snowiest place in California.
