Crystal Cave Map (2).jpg
Our biome that we traveled to was a cave in Pennsylvania. A variety of Gemstones, emeralds, or fossils can be found in the gave but it is more of a tourist attraction. Caves are dark places made of dissolving rocks that take thousands of years to make. Rock dissolves deeper and deeper into the ground until the land starts to concave downwards. They are some of the coolest nature made attractions around.
How are caves formed?
