Evolution & Archaeology Overnight Field Study Day 2: Stone Rose Interpretive Center Fossil Dig


By Adalyn:
We went to the Stone Rose Interpretive Center which was a place where we were taught about fossils and things like mineral stains. Mineral stains are rocks that fell into water the water that carried minerals embedded the minerals into the rock. Another thing they taught us was concretions. Concretions are metals like iron and steel that embed themselves in the rock. They also taught us about worm-tracks which were worm larva that fossilized. Then we went to a digging site where we could dig and scavenge for fossils. We could keep three fossils and an iron concretion, mineral stain, and worm tracks. After we were done we went back to the Stone Rose Interpretive Center where the volunteer archaeologists identified what types of fossils we found. We had a lot of fun searching and finding fossils.

We went to the Grand Coulee Dam which was built from 1933 – 1942. It is the biggest concrete structure in the world. They built it because the people’s crops were drowning. They finally thought that the Colombia River was flooding it. So they started to build the dam with tons of concrete. The Grand Coulee Dam is three and a half miles long, and about a mile down. The Grand Coulee Dam’s power was used for the Manhattan nuke in World War 2. We had a lot of fun at the Grand Coulee Dam!
