FALL ON ROCK, PITON AND NUT FAILURE

Alberta, Rocky Mountains, Yamnuska

Alan Fielding (34) was leading the second pitch of the Grillmair Chimney on Yamnuska at 1330 hours on 19 August 1978. He pulled off a loose block and fell. First a poorly placed angle and then a poorly placed chock pulled out. He fell 20 feet and was slightly injured. (Source: Lynn Michaud)

Analysis

Placing chocks and pegs should be thoroughly practiced and tested in safe situations before using them for real protection. (Source: Lynn Michaud)
