Back at Base Camp! And What a day we had! Our ascent to the summit of Copa was everything but ordinary; intricate navigation to avoid a blocking bergschund, trail breaking at 20,000ft, steep slopes in the dark... and a corniced summit ridge, among other factors, provided a great graduation climb in this, our second Peru Seminar. We managed to descend to the safety of Base Camp in a long push, picking high camp on the way. Everyone is pretty tired, but feeling well and accomplished. We are turning to our tents now, and will check in again tomorrow from Huaraz. Best regards, RMI Guide Elías de Andres Martos and team.
