Origin: Legends of the Seneca Native Americans
The dragon Gaasyendietha dwells in rivers and lakes locally. Although it is seldom described, it is said to be quite large. This dragon could cross into heaven on a trail of fire, and it could also spew fire. 
Some believe that the stories of Gaasyendietha exist because of meteors; others claim that Gaasyendietha is a meteor-fire dragon.
