In 2016, Haley and Alex Honnold completed two big traverses in Patagonia in record time. First they made the second ascent of the Torre Traverse in 20 hours and 40 minutes. A week later they made the second ascent of the “Wave Effect” traverse in 17 hours and 7 minutes, taking a more direct route than the first ascent, and with both climbers climbing every pitch free.
Haley has also garnered much attention in the alpine climbing community for climbing difficult routes in the Alaska Range much faster than previously thought possible. In 2016, Haley climbed the Infinite Spur on Mount Foraker solo in 12 hours and 29 minutes "'schrund-to-summit" - less than half the time required by the next fastest climbing party in 2001. In 2017, Haley climbed and descended the North Buttress of Mount Hunter in 7 hours and 47 'schrund-to-summit. Haley set the speed record for climbing the Cassin Ridge on Denali in June 2018 in 8 hours and 7 minutes 'schrund-to-summit.
