文摘

New geomorphological observations and exposure ages for Pensacola Mountains, adjaecent to Foundation Ice Stream, Antarctica. Exposure ages show modest Holocene thinning between 10 and 2.5 ka BP, similar to nearby chronologies in Ellsworth Mountains. Data provide constraints for ice sheet modelling and are consistent with recent hypotheses of retreat in Late Holocene.
