Macdonell Island East

St. Lawrence River

Ontario, Canada

The site is along the shore of the Eastern end of Macdonell island, right next to the remains of the old highway two as it goes into the river. Note that this creates a rocky shelf, where the current is very fast the further out you walk. Step carefully, or avoid the area.
The substrate is mostly rocky/sandy, but there is very dense macrophyte cover that may make it hard to walk. Luckily, the water here is very clear, so hazards are easily visible.
