Lamplugh Glacier, Tidewater glacier in Glacier Bay National Park, Alaska, US.
Lamplugh Glacier is a tidewater glacier in Glacier Bay National Park that flows through a deep valley of rock and ice over several miles. The glacier displays layered ice formations and calving faces where large chunks regularly break away into the water below.
The glacier was named in 1912 by Lawrence Martin of the U.S. Geological Survey after English geologist George William Lamplugh who had explored the region decades earlier. This naming choice preserved the memory of Lamplugh's geological work in the area.
Scientists monitor the glacier's changes to understand climate patterns and environmental transformations in the Alaskan wilderness over time.
The best way to experience this glacier is by boat tour from Juneau, with many cruise ships including Glacier Bay in their routes. Wear layers and warm clothing, as weather changes quickly and temperatures stay cool even on sunny days.
A major rockslide in 2016 dumped massive amounts of debris onto the glacier, creating a visible scar across its surface. This event demonstrates how geologically active the park remains and how quickly landscapes can change in this region.
