There are no contemporaneous written records of the [[1700 Cascadia earthquake]]. Orally transmitted legends from the [[Olympic Peninsula]] area tell of [[Thunderbird and Whale|an epic battle between a thunderbird and a whale]]. In 2005, seismologist Ruth Ludwin set out to collect and analyze anecdotes from various [[Native Americans in the United States|First Nations]] groups. Reports from the [[Huu-ay-aht First Nations|Huu-ay-aht]],<ref name=NatGeo/> [[Makah]],<ref name=NatGeo/> [[Hoh Indian Tribe of the Hoh Indian Reservation|Hoh]],<ref name=AMNH/> [[Quileute]],<ref name=Smithsonian/><ref name=AMNH/> [[Yurok people|Yurok]],<ref name=Smithsonian/> and [[Duwamish tribe|Duwamish]]<ref name=Smithsonian/> peoples referred to earthquakes and saltwater floods. This collection of data allowed the researchers to come up with an estimated date range for the event; the midpoint was in the year 1701.<ref name=NatGeo/>
