When Lassen Volcanic officially became a national park on August 9, 1916, virtually no roads penetrated its boundaries. Nine years passed before a scenic boulevard advanced toward Lassen’s isolated interior. One crew built south from Manzanita Lake and the other north from Sulphur Works. Promoters were so excited when the road opened, that a fake, pyrotechnic eruption of Mt. Lassen was employed to celebrate the highway’s official dedication on July 25, 1931.
