Falkner Island has been the site of human activity for thousands of years. An archaeological survey performed on the island from 1997-1998 found a quartz projectile point of the Squibnocket triangle variety which dates to 1000-3000 B.C. The study was conducted by the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service as part of the erosion control project; it was required by law under the National Historic Preservation Act because the island is on the National Register of Historic Places. The findings were published in the Bulletin of the Archaeological Society of Connecticut in 2001. In 1994, John P. Menta's "The History of the Quinnipiac Indians" identifies Falker Island as the site of ceremonial and religious practices, but that these practices are still unknown. According to Bruchac's "Thirteen Moons on Turtle's Back" the island was not a permanent settlement, but was likely used for fishing and hunting trips in the summer.
