Native sulfur crystals in Mauna Loa fissure
Detailed Description
Native sulfur crystals often form through the reaction of sulfur dioxide and hydrofen sulfide gases, both of which are degassing from this old fissure on Mauna Loa, making it an ideal site for volcanic gas monitoring. As a result of the degassing, the fissure is lined with yellow sulfur crystals.
