Meranda crotsley visiting

Today Meranda Crotsley came by and talked about the coal mines in Pennsylvania. She brought a lot of cool items that people that worked in the mines used. We learned about how going in the mines is really bad and how you may die when your in it. She also thought us that over time water finds its way down the mines and getting into the bedrock and causing it to break down the iron. Water can always find a way out and when it move out it can causes a lot of  iron to settle in the water making it hard to with stain life.
