Greenland Icebergs (IMAGE) American Geophysical Union Caption These icebergs are easily visible in the fjord from an area just outside of Ilulissat. They calved from Jakobshavn Isbrae (aka Ilulissat Glacier) earlier in the season, from the calving front which peaks at speeds of nearly 17 km/yr in mid summer.
