| | The 1972 Chouinard Catalog of hexentrics, stoppers, (pitons) and more |
 | | The only pitons available at that time were made of soft iron, placed once, then left in the rock. |
 | | For the next few years, Chouinard forged pitons during the winter months, spent April to July on the walls of Yosemite, then headed out of the heat of summer for the high mountains of Wyoming, Canada, or the Alps, and then back to Yosemite in the fall until the snow fell in November. |
 | | The same fragile cracks had to endure repeated hammering of pitons, during both placement and removal and the disfiguring was severe. |
