photo018:"Drilling and processing snow cores involves teamwork. While a new core section is being drilled, team members measure physical properties (e.g., volume, mass) and stratigraphy (i.e., the ice layering) of the previous core section. Processing the core in a snow pit allows shelter from the wind and creates a stable bench for examining the cores.",

The coring device can obtain one meter of snow and firn at a time, and by adding extensions to the drill, it is possible to carefully sample many meters deep without having to dig an enormous hole. Team members take careful notes to ensure records are complete.",

We also know that Alaska has many softwood forests, and that some have burned. But how can we tell which regional fires deposited aerosols on the glacier?",
