Mark Anderson[1. Not to be confused with his brother Mike who just recently repeated Mission Impossible], writing on his blog about the FA of a potential 5.14c in Colorado’s Clear Creek Canyon called Siberian Express:
I’m calling the route Siberian Express. Based on my maintenance training I can confidently say that I was in top shape when I did it. The weather likely extended the outcome somewhat, but considering my fitness and the twelve days required, I suspect it’s the hardest route I’ve climbed and warrants a 5.14c rating. More importantly, it’s a great route.
Mark also did the FA of Double Stout at Clear Creek back in January at a proposed grade of 5.14a.
