We report on scientific analyses of the only well-preserved ancient human body ever recovered from a North American glacier. The body was found high in the mountains of northwest British Columbia at about 80 km from the nearest point of the strongly indented coast of southern Alaska. The geographical location suggests that the young man, aged about 20 years, could have lived either on the mild coast or in the continental interior. Preliminary environmental scanning electron microscopy (ESEM) and light microscope studies of the contents of the digestive tract reveal pollen of an intertidal salt-marsh plant and pieces of a marine crustacean. Remains of coastal zone plants (a fruit of a flowering plant and a needle of a coniferous tree) had adhered to the deceased's robe. Stable isotope analyses of bone and muscle show that more than 90% of the dietary protein was from marine sources. We conclude that this individual had strong coastal connections during his life and had been on the coast shortly before he died about 550 to 600 years ago.
