Watch: Weird Waves // Idaho
From the Great Lakes, which Dylan Graves surfed in Part 1 of Weird Waves, to the great north-west of the US. Not the north-west coast, but the mountainous north-west of Wyoming and Idaho where spring snow melt from the Rocky Mountains flows down the rivers and various bottom contours give shape to waves like 'Pipeline', an imaginatively-titled standing wave in Idaho.
There's not too many barrels in Idaho, but it hasn't stopped a subculture emerging around the waves. They ride boards more suited to the waves - short, no-nose, parallel rails - and juggle their schedule around the CFS, or Cubic Feet/Second, the rate at which their local river is flowing, the metric that dictates the quality of each wave. The river surfers version of period and direction.
