"Arctic Expeditions"

"Sod house, mostly built from driftwood, whale bone, mammoth tusks and roofed with sod.  This had been a typical house along the Chukchi Sea beach regions.  Boats were pulled up the shore on rollers by villagers or carried to sheltered racks if they were kayaks.  Hunters along these sea beaches were constantly looking out to sea, with one 'eye' on shore for bears and caribou.  Raids were the occasion from the inland rivers by the Indian folk that had issues with the coastal Inuit and sometimes arrowheads were used for a different purpose."
