Seneca drums?
ETA; Seneca Drums
For hundreds of years, people around Seneca Lake have talked of strange "booms" coming from the lake. A long time legend, many have described the sound as one of distant cannon fire. According to folklore, the sounds are a message from the Iroquois who inhabited the area hundreds of years ago, while others believe they are simply the result of geothermal reactions.
Over the years, there has been no shortage of lively explanations for the thunderous booms that have arisen out of the depths of Seneca Lake. The most ancient myths, held by the Iroquois Indians, were considered mere superstitions by early white settlers. Nevertheless, the myths multiplied as the years went by.
Seneca Indians believed that the booming sounds came from the Great Spirit, who swallowed up Agayenthah, the tallest and bravest of all the warriors. Agayenthah was hunting bear and took refuge under a shoreline tree when a thunderstorm came. Lightning struck, and he and the tree fell into the lake. The following day, the Seneca people heard the drums for the first time, which they interpreted as the Great Spirit's curse upon Agayenthah's violation of sacred hunting codes.
Others claimed that the sounds were the drums of their ancestors, evil spirits inhabiting the lake, signals from the God of Thunder, or residual sounds leftover by the Great Spirit when the earth was created. Another myth described that the drumming came from a soldier from the post-Revolutionary War, whose actions taken against the Iroquois caused him to lose his way forever, searching for his regiment.
