Fieldwork in 2010 took place in late May and early June, shortly after the accumulation season ended. Over the course of 5 days at the summit, we raised the weather station tower, added new instrumentation, and conducted snowpit measurements. The following links provide access to images of the fieldwork.
The full field season is depicted here, beginning in Cusco.
For more detail about the automated weather station (AWS), images are available here.
Ascending to the summit on May 3oth, we encountered a surprise (shown here). Equipment installed on the glacier in June of 1978 emerged from the ice after being buried for 32 years.
