How long they might have been there is unknown. There were people living over 9,000 years ago at nearby Groundhog Bay, but we may never know who they were. A site on Baranof Island shows that people with an unmistakable northwest coast culture have been in the region for at least the last 3,000 years.
Even as Glacier Bay itself lay encased in ice, native people carried on their activities in many places along the nearby coast, places that may have been free of ice for as long as 13,000 years. The oldest known site in Glacier Bay National Park, located in Dundas Bay, is about 800 years old. Natives were at Lituya Bay, on the park's wild outer coast, to greet Lapérouse in 1786. Although a series of earthquake-triggered tidal waves, the latest in 1959, devastated most of the shoreline of Lituya Bay, a pocket of undisturbed forest still harbors archeological evidence of their life there.

Lungwort lichens get their name because their appearance is similar to lung tissue. Some lungworts are able to convert atmospheric nitrogen to forms that other lichens and plants can use. The presence of lungwort is an indicator of a rich, unpolluted forest habitat.
