Safety first. Here is a photo of Mike and I installing a GPS monument at a place called Pecora Escarpment. You can see the red harnesses we are wearing around our waists and legs, and the blue ropes we are tied into. That’s because we are actually on the edge of a cliff with a massive drop off just behind us, so we need to be roped-in to work. Peter and JR, our mountaineers, set up an anchor system just off the rock, and the blue ropes you see connected to us are tied into that anchor. So in the event that one of us topples over the cliff, we’re brought to a safe halt and Peter or JR can fish us out. We were lucky this day, because the weather was beautiful. About -18C (0 Fahrenheit) and hardly any wind. On a windier day it’s much easier to lose your balance when a strong gust rolls through, and it really becomes important to be roped in.
