Artesonraju. From July 22 to August 8 Michael Jacobson, Mark Levinson, James Lingerfeld, Kim Meyers, David Paskin and I climbed Artesonraju (19,766 feet). The ascent was made in three groups on two successive days via the standard route up the northeast glacier to the north ridge. Base Camp was at the foot of the glacier at 16,400 feet and one night was spent at 18,375 feet in tents. The route turned out to be relatively easy with only one ice pitch and never over 55°.
