Crawl pipe in this hillside leads into a maze of underground passages

This system comprises an upper series of predominantly natural caverns, and a lower series that has been more extensively modified by mining activity. The lower Series consists of a number of large phreatic chambers connected by smaller mined passages. ln addition to natural features, generations of miners have left their marks sometimes literally, and pick marks and candle soot can be found in many places.
