Fulgurite Outer Banks Sparks Viral Conversations Nationwide - Away State Journal
Fulgurites are geological features formed when lightning strikes the ground, fusing sand or soil into glassy structures. They are essentially petrified remnants of lightning strikes, capturing the intense energy and heat generated during the event. Fulgurites can range in size from small, millimeter-scale tubes to large, meter-long formations, depending on factors such as the energy of the ...
This type of fulgurite depends on shape and not soil composition. Where to Find Fulgurites Fulgurites form where lightning strikes, so it’s easiest to find them on mountain peaks, desert highlands, and beaches. Peaks known for fulgurites include the French Alps, Sierra Nevada range, Rocky Mountains, Pyrenees range, Cascades, and Wasatch range.
What Is Fulgurite? Where to Find It and How to Make It
A fulgurite is a glass tube formed when lightning strikes sand, creating 'petrified lightning.' You can safely make a fulgurite by using a lightning rod in an open sandy area during a storm. Fulgurite color varies due to sand impurities and is similar to obsidian in its make-up.
Sand fulgurite tubes have a glassy interior, due to rapid cooling and solidification of the sand after the lightning strike. The size and length of a fulgurite depends on the strength of the lightning strike and the thickness of the sand bed. Many sand fulgurites average 1 or 2 inches in diameter and can be up to 30 inches long.
