Open cut of the Homestake Gold MineNow let us digress and I will tell you about what we actually did today. Today we visited the Homestake Gold Mine in Lead, SD. While the mining operations ceased in 2002, the mine is still the most profitable gold mine in the US to date, having harvested over 40 million ounces of gold. In 2002 the mine was sold to the state of South Dakota, by the Berrick company, with the stipulation that it never be used for mining again. The mine is now being used for scientific research about neutrinos and dark matter, as well as a tourist and education center for the history of the mine and mining on general in South Dakota. After a trolley tour and a talk concerning the geology of the mine with the geologist who is helping with the closing of the mine, we had a lunch of pasties ( think handheld meat and veggie pies) which were the traditional lunch for the miners and headed back towards Stockade Lake for our final night of camping there via the Needles highway.
View point of cathedrals and spires off of Needles HighwayNeedles highway is a scenic route through the Black Hills, which showcases the impressive pegmatites in the region. Pegmatites are rock formations bearing very large crystal structures. In the Black Hills, the pegmatites include feldspars, quartz, micas, and occasionally tourmaline. The verticle faulting creates magnificent spires and "catherdral" structures which attract avid rock climbers from all over the world. In fact, while we were at an overlook a couple climbed up and repelled down the famous "Eye of the Needle" that is right off of the highway. It was awe-inspiring to watch, and I feared for their safety until they were back safe on the ground. That is definately one sport that I don't think I could ever get into.
We eventually made our way back to the campsite, where my cooking group made taco salads for dinner. After dinner we spent sometime around the campfire, eating smores and talking about life. I retired to bed early for some much needed alone time, just to read and be with my thoughts, and now as our last day at Custer State Park comes to a close, I will fall asleep listening to the steady, drip drip drip, of rain beginning to fall on the tent fly.
