Calistoga's economy was based on mining (silver and mercury) agriculture (grapes, prunes and walnuts) and tourism (the hot springs). One of the early visitors was Robert Louis Stevenson. Yet to write his great novels, he had just married Fanny Vandegrift in San Francisco in May 1880, and the couple honeymooned at the Calistoga Hot Springs Hotel days later. Desiring to stay in the area, they moved from the hotel to an abandoned cabin at the nearby Silverado Mine on Mount Saint Helena. While working on other stories Stevenson kept a journal which became the "Silverado Squatters" describing many local features, residents and characters.
