Colorful hornito in the eastern part of Halemaʻumaʻu
Detailed Description
A hornito located on the eastern side of Halemaʻumaʻu crater floor. The colorful nature of the hornito comes from the various gases that come out of the magma and precipitate on the surrounding rock. Many of these colors are from sulfur that is abundant in Kīlauea magmas. USGS photo by D. Downs.
