In 2011 September, Bob and Diana spent three days exploring Lake Travers (Lake Traverse) on the Petawawa River in Algonquin Park. That exploration is illustrated here. Major points of interest include: the logging dam at Big Thompson Rapids on the Petawawa River; the Pembroke Lumber Company; and the De Geer moraines, which lie to the east of Lake Travers. This trip is described in more detail in Trip Log - Exploring Lake Travers and two other pages referenced therein.
