I mention this because it turns out that's the last canoe trip Angela and I would take for the next 3 years. We bought our property on Clear Lake that winter, and when the ice thawed in 2013 we devoted the next 3 years to building our tiny house and the Clear Lake Eco Retreat. Although we've spent much of those 3 years canoeing the 2.5 kms back and forth to the Lost Channel Marina and paddling folks out into the surrounding back country on fishing trips, Angela and I have not taken the time to go on a long distance canoe camping trip since 2012, that is, until now.
making the connection
As seen on the above map, our trail to Courtney Lake spits you out on the water just as it intersects the Blair/Brown township border. The exact divide is, in fact, indicated with a metal survey marker which we were lucky enough to stumble upon.
If you ever get the urge to try this portage, don't. It's no fun. For us that day it wasn't about the fun. It was about making the connection.
