History
History
• Illustration — Replicas of a plaque left by Russians on Mount Saint Helena Mount Saint Helena has had an explosive history of pyroclastic flows that resulted in California's Petrified Forest. Mount Saint Helena, originally named Kanamota ("Human Mountain") by the Wappo, and later Mount Mayacamas by Spanish colonists, was renamed by a Russian survey party who ascended the peak in 1841. They left a copper plate on the summit inscribed with the date of their visit and the name of Princess Helena de Gagarin, wife of Alexander G. Rotchev, the commanding officer of Fort Ross. The peak is accessible by hiking trails leading from Robert Louis Stevenson State Park. The trails are approximately 6 mi long. Scottish writer Robert Louis Stevenson and his wife Fanny Vandegrift Osbourne spent the summer of 1880 honeymooning in an abandoned mining camp on Mount Saint Helena. Stevenson's book The Silverado Squatters describes his experiences while living there. A state park was named after him near here.
