Location description
Easily accessible location beside the boat launch where the picnic table sits . This is close to the eastern most point of Larder Lake where the river flows into the lake from other lakes. This is also where the Kerr Adison mine operated for many decades as one of the largest gold mines in the world at the time of it's peak production. Back then mine tailings were routinely dumped directly into the lake here...fortunately the mine has been closed for a long time.
