Lassen Volcanic National Park Professional Review and Guide
"Lassen Volcanic National Park was set aside because of its volcano, Lassen Peak, which erupted explosively in 1915. What is often lost sight of is that it is also a place of wonderful forests, lakes, meadows, and subalpine slopes, still relatively undiscovered by many. The high standard road through the park reaches its high point near Lake Helen, just below timberline.
