which is located further east, The Susquehanna and Tidewater Canal or the Portage Canal?
Portage Canal The Portage Canal was built to connect the Fox River and Wisconsin River at Portage, Wisconsin along the Fox-Wisconsin Waterway. For a time, it completed a route from the north Atlantic Ocean, through the St. Lawrence Seaway and down the Mississippi River to the Gulf of Mexico, and back to the Atlantic.
Frog Portage Frog Portage or Portage du Traite was one of the most important portages on the voyageur route from eastern Canada to the Mackenzie River basin. It allowed boatmen to move from the Saskatchewan River basin to the Churchill River basin. The Churchill then led west to the Mackenzie River basin. The fur trade route ran from Cumberland House, Saskatchewan north up the Sturgeon-Weir River. At its source the 300-yard Frog Portage ran, with a 20-foot drop, to Trade Lake on the Churchill a few miles west of the mouth of the Reindeer River. The route then ran at least 250 miles northwest up the Churchill to Methye Portage which led to the Mackenzie basin. For background see Canadian canoe routes (early).
