Glacial history & landforms

20,000 years of icework, and its expression on the land

At Juneau, marine sediments dating
to 13,000 BP have been found at 750 feet
above sea level. Considering world sea
level was more than 300 feet lower at that
time, this represents more than 1000 feet
of land depression under heavy ice.
