Pele's hair from Mauna Loa eruption

Detailed Description

These Pele's hairs were collected along the Saddle Road many kilometers (miles) away from the eruptive vents. They were carried downwind and deposited across the landscape. Each hair is less than 1 millimeter (0.04 inches) wide and they form as lava pulls and stretches as it cools during eruption. Photo taken at around 10:45 a.m. on 29 November 2022, USGS photo by K. Lynn.
