mirth: "You want it to be nice and wet in the weeks before your trip, otherwise the 3 marked portages on the Horse will be more like 7 or so along with boulder hopping." Ditto. There will likely be many more port ages than indicated on the maps. Still, it will be passable and a great trip.
I am not sure if was September or October, think September, and think 2015, not sure, but we had NO RIVER and ALL BOULDER FIELD on our trip. This along with the fact that we weren't not able to get down the river in the daylight, and quarter size snowflakes after dark so our headlamps were worthless, on of the rougher trips that I have ever had. I had to turn off headlamps and just try to see outline of treeline when we came out onto the lake. The bay on the lake also is full of boulders, and it was windy.
