This is a fine example of this classic Utah pseudomorph. This one comes from different pocket and from an earlier period at the mine. As opposed to the usual interpenetration cubes that are best-known, here you have razor sharp octahedral crystals (to just under 2 cm along the edge). They actually look something like those Bolivian magnetites.
