Sounds like a pretty good plan to me but I would contact Jim Hegyi and see what he would advise on the Irr. to Eagle route. I took a little walk on the first 500 out of Irr. and was really glad I was not portaging it.

The paddle up the Talon and through Boomerang with be the payoff for finding your way to Eagle. The picture of my GPS mounting system at the start of the Creeks and Trails story on canoestories.com is on the way to the 375 portage to Dragon. As I recall those little ponds on the route are not as big as they appear on the map. Note how there are two ways to exit the pond preceding the portage. This is one of those places where a GPS's Topo map will let you know that you are in the right pond and the little crease in the grass is the stream you want to take.

I have not been further than Musclow but Bill Fulton makes a few comments in a canoestories journal about Job to Musclow.

Seemed pretty clear to me. I don't think much stops Marten...

Wear your brightly colored PFD, as mom said, to make it easier to find the remains...

AHH, the memories of great days in WCPP. As you are aware the weather up on those big waters is the limiting factor. I agree with the draw those waters have on a person when drooling over the maps in the off season. I had just the right winds on my foray into Musclow. An early start on Dunstan and tailwinds all the way to the top of Musclow. A quick supper and then an evening paddle back down those ominous waves of the big lake. On those big waters the kilometers can fly by but the wind can mess with your dreams.

Now for my thoughts on the Irregular to Eagle route. I walked some rough country on the 500 meter exiting Irr. and then came to a bog of stunted Spruce. The trail had seen no use to compress the deep moss and had numerous small trees fallen across it. The next day I exited Irr. on the 825 to the east. It was a hard portage and my notes say it was not as bad as the 500. Canoestories has many stories from some guys that do most of their WCPP entries from the south. I do not remember them ever writing about going to Irregular but figure they have or knew not to.
