2007 - $20 - International Polar Year - Proof $20 Silver

Hundreds of years ago, the Arctic was viewed as the gateway to the world. Today, it is viewed as the key to understanding it.

The first polar explorers, the Inuit, had been comfortable living in the Arctic for thousands of years, but for the Europeans, it was a harsh and mysterious place—and the need to study this unknown land became abundantly clear as Sir Martin Frobisher searched for the Northwest Passage in 1576. The arrival of the first Englishman there was likely to fuel notions of empire-building back home. Arctic settlement seemed inevitable and with that in mind, Frobisher constructed a house of lime and stone so the Arctic's effects on its structure could be observed.

In 1882, growing consensus among scientists prompted the launch of 15 coordinated expeditions to the Arctic and Antarctic—the first International Polar Year.

Much has been learned since that first Polar Year 125 years ago and much remains to be understood about the polar regions—their climate, environment and their inter-relationship with the oceans, atmosphere and other land masses.

The historic search for the Northwest Passage did indeed reveal that all parts of the globe are connected, but as the next Polar Year will continue to show, that connection reaches far beyond the scope of a trans-Arctic trading route.
