A small group of caribou (Rangifer tarandus) migrating north to feeding grounds in the spring from Yellowknife, Northwest Territories, Canada. MORE INFO also known as the reindeer this animal travels the furthest of any terrestrial mammal, traveling up to 5,000 km (3,100 mi) a year. The caribou can run at speeds of 60?80 km/h (37?50 mph). Caribou often use the ice road for ease of travel through deep snow areas.

Details of the ice road from Tibbitt to Contwoyto beginning just outside of Yellowknife, Northwest Territories, Canada. MORE INFO This seasonal ice road is built through the lakes and ponds of the boreal forest in winter to allow heavy trucks to suppy fuel and logistical support to diamond mines in remote northern Canada. It is mostly used at night, when temperatures are at the coldest and safest. In the 2009-2010 season over 6,000 truckloads of supplies and fuel utilized this  ice road.
