In 1970 Warren Harding and Dean Caldwell accomplished the “Greatest climb in American history” with the first ascent of the Wall of Early Morning Light. 44 years later, in January of 2015, Tommy Caldwell and Kevin Jorgeson completed the historical first free ascent in 19 days, following after 7 years of effort. A year later, Czech climber Adam Ondra added to the history of the Dawn wall by free climbing it nearly unrehearsed, in a mere 8 days.
