Part 2 - Headwaters: Abitau, Dubawnt, Thoa, Marten
The inflow from a major tributary draining Alcantara Lake adds to the Thoa’s volume below Sorenson. Navigable rapids are scarce. With portaging conditions difficult through the old burn, slow but steady wading and lining is usually the best choice.


Nice sandy campsites still turned up when needed.

Followed by more rapids.


The weather for the trip was uncharacteristically hot, with daytime highs often in the 30s. The heat generated some impressive cloud formations, but only an occasional sprinkle of rain.

Leaving the Thoa and heading up the Marten brought different challenges: the volume of water was much reduced, but it was going in the wrong direction. Progress was slow but steady, portaging was often a challenge in the old burn.

At my first campsite on the Marten, I found this old trap buried in the moss. It was reassuring to know that someone had been here before.

The next day I passed my old trapper’s cabin, set on a high sand bank above the river.

The Marten was a lot of work, but it redeemed itself by continuing to provide good campsites for rest and recovery.

The next day I passed a more modern cabin on the Marten. It was built by the Water Survey of Canada, likely in the 1980s, when there was a flow monitoring station located here. Flows on the Marten have not been monitored since 1990.

Rapids, now increasingly bedrock defined, continued all the way up the Marten.



I was glad to surmount the last rapid, with one final bush crash portage, and reach the good-sized but unnamed lake where my trip would end. It was an attractive place, with beaches and lots of sand in evidence. It provided me with one last good camp on a sandy ridge, with a private reflecting pool and a perfect airplane beach adjacent.



A final smoky sunset provided some photographic opportunities.


And then the plane arrived on time the next day. Another trip was over, and it was time to start thinking about next year’s route.

Trip totals were 18 days, 286 km, with 27 portages and LOTS of wading, lining, and dragging.
I hope you’ve enjoyed this trip summary. I’d be glad to provide more information to anyone interested in this area.
