Chipmunk Drill

Description

The Chipmunk Drill is a hand-held, motor driven drill that collects 41 mm (1.6-inch) diameter cores in solid ice. It has two barrels, one 15 cm long and one 50 cm long. The drill was first used for a funded project (for which it was designed) at Pakitsoq, West Greenland, in 2003 and 2004. It was later used for exploratory work at the South Pole in 2013 and for several demonstrations of ice coring for the public in the U.S. More recently, the drill was used to collect shallow cores in the Sierra Nevada range in fall 2021 and in Wyoming in fall 2022. During winter/spring 2022, the drill was used by an investigator at UW-Madison for testing highly strained ice created in a campus lab.
