If you read the caption on mindat, it states, “This specimen was discovered in 2003 after pounding a large boulder with a sledgehammer for a few hours.” What The Captain neglected to mention was WHO was wielding that hammer.
I always thought it was always a great stress reliever... whacking rocks with a big hammer. And every now and then we would find something good like those wires.
I think the wires form because copper is part of the cubic (or isometric) crystal system and the wires are basically elongate cubes-- one side of the cube grows faster than the others. But as to exactly why that happens... I don’t know. I think I’ll pour myself another mug of mead and ponder that a while. Skål!

Love the "wire" photos. Well, I loved all the photos!
