Flying off the West summit of Wy'east into Leuthold Couloir. Was hoping to fly the Reid Headwall, but I neglected to traverse left earlier in the flight and instead dropped into the massive couloir. Clouds were building at the base of the mountain and winds were beginning to shift to the wrong direction as I prepared for launch. Definitely snagged the momentary window before conditions turned for the worse. Was a committing launch as it was steep and icy dropping over a headwall.
