Johns Hopkins Glacier, Tidewater glacier in Glacier Bay National Park, Alaska.
Johns Hopkins Glacier extends 12 miles from Lituya Mountain to Johns Hopkins Inlet, reaching heights of 250 feet above the water line.
Harry Fielding Reid named this natural formation after Johns Hopkins University in Baltimore, Maryland during his 1893 expedition to Alaska.
Scientists from multiple research institutions conduct regular studies at the glacier to monitor climate changes and glacial movement patterns.
The glacier remains accessible only through boat tours in Johns Hopkins Inlet, with strict navigation guidelines protecting the marine environment.
Two distinct meltwater channels near the eastern and western edges release glacial flour, creating visible upwelling patterns in the inlet water.
