Thin strands of volcanic glass that form when lava ejected from a volcano is spun out and stretched by the wind.
Fine, hairlike filaments of volcanic glass formed naturally from molten lava that hardened while it was subjected to high winds or other turbulence.
Origin of pele-s-hair
- Translation of Hawaiian lauoho o Pele from lauoho hair of the head (lau leaf, frond) (oho hair of the head) o of Pele volcano goddess (from pele lava flow)
