No, we need something more. Perhaps aluminum foil boats as well?

(How about some copper clad boats?)

A Short History of Copper Mining (Michigan)

Copper was first mined in this area by an ancient vanished race between 5,000 and 1,200 bc. These miners left no burial grounds, dwellings, pottery, clay tablets or cave drawings. What was left behind was thousands of copper producing pits and more thousands of crude hammering stones with which the pits had been worked. The ancients apparently worked the copper bearing rock by alternately using fire and cold water, to break the copper ore into smaller pieces from which they could extract the metal with hand held hammering stones or stone hatchets. With this copper, they made tools.

Scientists and engineers estimate that it would have required 10,000 men 1,000 years to develop the extensive operations carried on throughout the region. It is estimated that 1.5 billion pounds of copper were mined by these unknown people.

The pure copper of Lake Superior has been discovered in prehistoric cultures throughout North and South America.

The mystery of their origin remains unsolved. The mystery of their disappearance remains unsolved.

Many hammered copper knives, arrow and spear heads and axes were recovered at ancient mining sites. Some fine examples are on display at Fort Wilkins.
