In Hawaii Volcanoes National Park, most visitors are on the lookout for liquid magma, but astute observers may notice something even more perplexing: clumps of glistening, golden threads blowing in the winds. The hair-like strands can stack so high you'd think Rapunzel was sheared nearby.
Volcanologists call it Pele’s Hair, after the Hawaiian goddess of volcanoes, but the golden strands are actually fragile volcanic fiberglass.
They're formed when lava is ejected into the air and small droplets are caught by the wind, which then cools and stretches them into very thin strands. Some threads can reach as long as 6 feet and are most likely gold in color due to weathering effects, experts say.
Pele’s Hair (as well as Pele’s Tears, which are the thicker ends of the strands) can tell geologists information about that lava’s history. For example, by looking closely at the strands' small crystals, scientists can tell eruption temperatures as well as the magma's path to the surface.
Pele's Hair can be found on other volcanoes in the world. In Iceland, for example, it's called “Nornahár," or Witch’s Hair.
Unfortunately, as with most things related to lava, you shouldn't touch them. The glass fibers can be sharp and get embedded in your skin if you're not careful.
Check out the pictures of Pele's Hair below, and for more information on where to find it, visit Hawaii Volcanoes National Park.
