The document summarizes a field trip to an emerald mine in Hiddenite, North Carolina led by Ed Speer. Nineteen attendees toured the mine, which is a crushed stone quarry operating in folded gneiss rock. The group examined a newly discovered pocket in the dark host rock, hoping to find crystalline minerals like emeralds. While no emeralds were found on this trip, the owner used tools to further open the pocket for inspection. Emeralds are only discovered in about one in four or five pockets.
