I had two friends who had never been on a glacier climb,so I choose Mt baker coleman deming route for their first climb. we left our 6000' high camp at 4:30am, on route we passed 5 rope teams before reaching the saddle at 9000'. we took a 20 minute break to let 2 teams get up the deming glacier. When we started our break the 2 teams were at a large rock 5/8's the way up the final pitch. we took our break then headed up. At this point the two teams had progressed only 75 to 100 feet above the rock. We headed up and caught the teams only 50 feet higher then when we left the saddle.We were now on the face next to the roman wall.The two teams had 60 meter ropes and were tied into the very ends. this had them getting tons of slack between climbers, which in turn would snag on surface ice chuncks. They then would stop to pull on the rope until the ice chuncks would come loose. After one episode like this I made the desicion to traverse closer to the roman wall and up to the summit.The details were we climbed from 9000' to 10000' in the time they climbed from 9900' to 10000'.It seemed like we had left plenty of distance for them to get up to the easier grade, but I underestimated how slow they were moving.what do you do when you come on to teams that are a danger to your team? In traversing closer to the roman wall we were exposing ourselves to greater rock fall danger, which I felt was safer than the ice chunks these teams were sending down on use. I also worried that they would tumble down and take us with them. What is the best way to deal with inexperienced teams?
