The David Thompson Highway runs east-west in central Alberta. One end begins at the Saskatchewan River Crossing in Banff National Park, heads 200 miles (321 km) east to end just past Nevis, Alberta. It is a beautiful highway to drive and about 20 miles of it follows the glacial blue-coloured Abraham Lake. The lake is man-made, created with the building of the Bighorn Dam in 1972. We drove it in the Fall of 2008 and the colours were incredible.
