Documented natural events that sound made up.
A natural phenomenon or event, verifiable in the scientific record, that reads as implausible.
Strands of volcanic glass over a metre long and under a millimetre thick, spun from lava the way sticky dough pulls into threads. The USGS advice for finding some is to leave it alone.
The USGS puts the impactor at about 30 metres across and 100,000 tons, arriving at 12–20 km/sec with the force of over two million tons of TNT. The hole it left is 1.2 km wide and 180 m deep.
