The Great Lakes
Surfers on the St. Lawrence River near Montreal catch endless waves each summer, as do off-season skiers and snowboarders in Wyoming's Snake River near Jackson Hole. But for a growing number of boarders, the best place to catch saltless waves is in the Great Lakes.
North America's five sea-sized lakes may lack the ocean's consistent waves, but the crests reach oceanlike heights in some places. When conditions are right, 3- to 5-foot waves are common, with some spots offering storm-created swells that rise to 10 feet. Weather buoys occasionally record 20-footers on the lakes after especially harsh storms. (The waves that sank the Edmund Fitzgerald, the famous Great Lakes shipwreck, were thought to be about 30 feet.)
