Denali | NSF Ice Core Facility

General Information

An 8 cm diameter, 208 m long surface-to-bedrock core dry drilled in May-June 2013 from the summit plateau (3900 m) of Mt. Hunter, located within Denali National Park in the central Alaska Range. The site is characterized by a high snow accumulation rate (1.4‐m w.e.) and cold mean annual temperature (-17 °C) (Polashenski and others, 2018). The period of record in the core is ~810-2012 CE (Winski and others, 2017).
