Lake Coleman

Lake Coleman was a large lake, in the same basin as Lake Ontario, during an interglacial period, approximately 75,000 years ago.[1] Its level was 20 metres (66 ft) higher than Lake Ontario.[2]

Lake Coleman was named after Arthur Philemon Coleman, a respected geologist whose excavations played a role in discovering the existence of the lake.[3]
