| In addition to the deposits found within the rather shallow depths that have been explored, erosion and several stages of glaciation have probably removed others, and still more may exist at greater depths, at least to the lower limit of the transverse veins within the Central Quartzite unit. Depressions in the surface of the land that hold water might have been formed by glaciation and subsequently fed by surface runoff and springs beneath. We're thinking there's no way metals can move through clay 10,000 years after glaciation. |
