Lake Toba is another of the island's spectacular sights - a remarkable volcanic crater set in the middle of northern Sumatra, 176km from Medan.

Winnipeg sits at the meeting point of the Red and Assiniboine rivers, a location that has shaped its role as a gathering place for thousands of years.

Matanuska Glacier is one of Alaska’s largest road-accessible glaciers, flowing through the Matanuska Valley northeast of Anchorage.

The Glenn Highway follows the Matanuska River valley and provides access to viewpoints and guided glacier tours.

Yuma is a city in southwestern Arizona near the Colorado River, close to the borders with California and Mexico.
