Abstract
Across North America in 2007-2009, communities will celebrate the David Thompson Bicentennials. For 34 years the great explorer, surveyor, and fur trader travelled across the continent, finding and mapping the routes between the St. Lawrence and the Pacific. Trusting the stars and his sextant, he surveyed a continental area so vast it remains a mapping achievement unequalled in human history. This is the story of David Thompsons epic journey his trail by stars.
