During the most recent ice age, the Alaska Range and all the land south of it was beneath an ice sheet. Little Ice Age (LIA), climate interval that occurred from the early 14th century through the mid-19th century, when mountain glaciers expanded at several locations, including the European Alps, New Zealand, Alaska, and the southern Andes, and mean annual temperatures across the Northern Hemisphere declined by 0.6 °C (1.1 °F) relative to the average temperature between 1000 and 2000 ce.

Answer: curious people who spot rock aprons draped over mountainsides and see tongues of extinct glaciers. The last glacial period is often colloquially referred to as the "last ice age", though the term ice age is not strictly defined, and on a longer geological perspective the last few million years could be termed a single ice age given the continual presence of ice sheets near both poles. They are based on analysis of 11,500-year-old chum salmon bones found by University of Alaska Fairbanks anthropologist Ben Potter and colleagues at the Upward Sun River site in Interior Alaska.
