Bright red Cuprite coating on Copper crystals. It's not quite this bright of red. Cuprite always comes out redder with the digital process. But, it is still a nice brighter red than a brick red. The Copper crystals are from 1 to 5mm and are all well-crystallized showing good dodecahedral forms sometimes crudely stacked. Deeper in the "roots" of the main group there are curled wires on the order of 1mm. There is a fascinating and exciting article about this find in Rocks & Minerals (v84 n1, 2009 Jan/Feb) by Tom Rosemeyer. 

In 2008 expert divers Bob Barron and Karl Peterson located this pocket in about 10 feet of water in Lake Superior. If you get the chance, read the article. They say the crystals of these specimens are some of the best Copper crystals ever found. That includes the mainland.
