So today we got to tour the Butte copper mine, which is home to the Berkley Pit. The Berkley pit is the largest Superfund site in the US. The 40 billion gallons of water now filling this abandoned open pit mine has the pH of around 2, meaning it is about 5 orders of magnitude more acidic than your average water. In addition to learning about acid mine hydrology, we got to spend some time looking at the Continental pit, which is still in production. They mine Cu and Mb with very small quantities of silver. I got to take some cool samples home of some copper carbonate precipitates that are green and blue along with some amazing copper-pyrite minerals.
I got my scores back from the Saturday field test. I made well above average which was nice. The average was 6.78 and I got an 8.35 out of ten.
Today was the first day in a long time that I haven't had a lot of work to do in the evening. I ended up playing two games of horseshoes and 3 rounds of volleyball to relax. It has been extraordinarily nice to have nothing to do in the evening for once.
