  Alaska showing tree-ring sampling sites
              and meteorological stations
  Seward, Alaska showing journey of Napauruhk

  (above) Map of Alaska and Canada showing departures from mean maximum latewood density for the year 1783 at various tree-ring sampling sites. Note the concentration of low values in northern Alaska.

  (above) Map of Alaska showing the tree-ring sampling sites and meteorological stations used for estimating summer temperatures.
  • The solid circles are meteorological stations:
    UES=University Experiment Station, MKP=McKinley Park, FTY=Fort Yukon.
  • The solid triangles are tree-ring sampling sites:
    FTR=412, ARR=Arrigetch, SRV=Savage River, TMS=Twelve Mile Summit.

  (above) The western and southern coast of the Seward Peninsula where the explorer reports came from and the events in the oral history took place. The map shows places named in the written accounts of early explorers and the oral history. The dashed line is the journey of Napauruhk alone with her son starting at Cape Darby to Sinuk, where they found other survivors, and to the Tisue River where they found their first abundant food and lived for many years. Sixteen days were on drifting sea ice (dotted line).
