Acidic Geyser
Millions of spine-shaped deposits surround Echinus Geyser. Iron, arsenic, manganese, and aluminum are all found in the acidic fountain of water that showers the landscape. With each eruption, these metals help build miniature rust-colored sinter spines.Expect the Unexpected · From 1878 to 1948, Echinus Geyser rarely erupted. Since then, the geyser has fluctuated between periods of activity and dormancy. · For many decades, Echinus has surprised observers with changes in eruption heights, lengths, and intervals. · Echinus erupted quite regularly for several years during the 1990s. · Eruptions can occur hours, days, or even months apart.Echinus was named in 1878 when mineralogist Dr. Albert Peale studied the geyser's deposits. They reminded him of the spines on echinoderms - starfish and sea urchins.| HM Number | HM1O9Q |
