Speed

Canadian Geographic - - DISCOVERY INFOGRAPHIC -

As a truck drives over an ice road, it dis­places the ice and wa­ter be­neath. A loaded truck trav­el­ling at an aver­age of 25 kilo­me­tres per hour cre­ates a lo­cal­ized bowl-shaped de­pres­sion, while a faster truck can trig­ger wide­spread ice and wa­ter waves that can crack the ice. Loaded trucks must slow down to just 10 kilo­me­tres per hour when en­ter­ing and ex­it­ing an ice road.
