The Halemaʻumaʻu Crater (essentially a lake of lava) on Hawaii’s Kilauea volcano has been erupting recently, and one researcher found a glass-like black piece of lava rock that looks like a “dragon egg.”
A Hawaiian Volcano Observatory geologist found the rock following a rockfall and explosion at Kilauea, reported the Honolulu Star-Advertiser.
“It’s an incredibly curious thing,” said Tim Orr, who is a geologist with the observatory. “Nothing like this has been seen before.”
The glass volcanic rock is around the size and shape of a Pele’s tear, but it’s hollow inside.
