The “Laker Pocket”, considered the most significant find of crystallized copper even made from the bottom of Lake Superior, was discovered by Bob Barron and Karl Petersen in August of 2008, just offshore near Eagle Harbor, Michigan. The find yielded approximately 200 pounds of good to outstanding crystallized copper specimens, showing a fascinating variety of morphologies including tetrahexehedra crystals, spinel twins, and even rare octahedral crystals. This cabinet-size specimen, retained by Barron in his personal collection after the find, is one of the finest specimens in this size range from the find, and consists of a highly 3-dimensional network of sharp, twinned crystals forming chains of the ‘herringbone’ style, studded in between by sharp individual copper crystals to ~8 mm. This superb copper specimen displays well on both sides and has a rich brown patina. A notable specimen from this major one-time find. Annette Slade photo.
