River Tay
The River Tay emerges from Loch Tay at Kenmore, and flows from there to Perth which, in historical times, was its lowest bridging point. Below Perth the river becomes tidal and enters the Firth of Tay. The largest city on the river, Dundee, lies on the north bank of the Firth. On reaching the North Sea, the River Tay has flowed from west to east across central Scotland.
York Factory
York Factory is located on the north bank of the Hayes River about inland. The mouth of the Nelson River is to the north, across "Point of Marsh". The Hayes is a more practical canoe route, although the Nelson is much larger (it drains Lake Winnipeg). Seagoing ships anchored at Five Fathom Hole from the fort due to the shallow bottom, and goods were transferred by smaller boats. The Shamattawa Airport and Gillam Airport are close.
