June 29, 2022 — Hornito degassing on the surface of Halema‘uma‘u, Kīlauea

This image shows a small hornito degassing on the surface of Halema‘uma‘u crater floor, at the summit of Kīlauea. Hornitos are small, rootless cones that are fed by the tube network within the lava lake. Alteration from the persistent degassing is what causes some of the variation and color you can see in the area around the hornito (note the yellows and reds). USGS photo by L. Gallant.
