Florez bends a flexible rock! Notice the
curve in this side profile of the itacolumite
specimen. The sandstone is interbedded
with mica, creating a flexible mixture.
It was quarried from the aptly named site:
Bending Mountain, N.C. The rock was used
for curved garden benches in the Victorian
era.

Strike! Morgan Little presents a fulgurite.
Sand fulgurites are produced when lightning
strikes a sandy beach, fusing the individual
grains together, forming tubular samples
like this one.
