Monday Geology Picture: Pele’s Hair

Posted by Evelyn Mervine

Pele’s Hair – or “Cheveux de Pele” in French.

For this week’s post, here’s a picture showing a lovely example of Pele’s Hair, which is a type of volcanic glass that consists of fibers or thin strands.

Although I’ve visited many volcanoes (including a few active ones) over the years, I’ve never seen Pele’s Hair in the field. So, I was quite happy to see this excellent example in the volcano museum on Réunion Island. I visited the museum during my vacation to the island last year. If you ever find yourself on the island, visiting the museum is a must. There are all sorts of wonderful displays and examples of different lava types, including this fantastic Pele’s Hair sample.
