This daguerreotype image, captured in 1855 by Hugo Stangenwald, is the earliest known photograph of Kīlauea Volcano. Although scratched and faded, the 161-year-old photo shows a line of steaming vents across the floor of Kīlauea’s summit caldera as viewed from a location near today’s Volcano House Hotel. The caldera rim is visible in the lower third of the image. Photo courtesy of Hawaiian Mission Houses Historic Site and Archives (http://www.missionhouses.org/).

Volcano Watch: When were the first photographs of Kīlauea Volcano taken?
