Drill Bits and Dynamite....Part Twenty Three....Ropes and Harnesses

The  Sea to Sky project required that workers on the rock crews ( scalers and blasters ) had to work from ropes... and rappel into work positions from time to time. Sometimes the height wasn't all that much....other  times it was a very long ways off the ground. Here is a video of how it works ( not Sea to Sky ) This is a photo essay with descriptions of the action Rock scalers Arlen and Tim helping to load blast holes on Cut10 Scalers working on cleaning up a safety trim shot to remove dangerous loose rocks  loading a shot...hanging from a rope....below the Upper Levels Highway and above West Vancouver houses Blaster Paul Cooper loading a shot at Cut 10 with help from Arlen and Tim Arlen hanging out and loading explosives into blast holes Tim's happy to be there Great view from Cut 10 bench...Mike T at the bottom helping  out A cluster of scalers on Cut 4...a cold and crappy day Scaling crew hand drilling a blast round on...

Fiber-optic lines right above ( expensive to tear up ) The fairly large shot that is flinging blast mats around is at Cut 4...fairly c...
