I"ve hunted that area since 1972. I've used Weasels (old military tracked vehicles), Bombadiears (canadian track rigs), Homebuilt half tracks, Swamp buggies, Nodwells, Susvees, Rollagons, and 4 wheelers. I will no longer take a 4-wheeler into that area, if I have an alternative, till after freez-up. Once the pot-holes freeze over, and the mud gets stiff, it's nice riding.
From Clear Sky lodge, go North about 300 yards from their parking lot. Cross the road, and take the dirt road. Then take the first left, about 200 yards. Thats the beginning of the trail. You will be going North, for about two miles. Then the trail will turn right (east), and you are on your way. Seven miles in, you will come to seven mile lake (Rex Lake), it is kind of tough getting around the south end of the lake, especially if it has been raining. Then it is about ten more miles to the first river (Totatlanikia). If you arent fed up with fighting mud, and can get across the river, there is a big meadow about two miles east of the river. When you get to the meadow, there is a small pond on the southeast end of the meadow, where I have often found Moose.
If the river is up, you can usually find a shallow area upstream, where you can cross. The trail after the meadow is a lot worse than anything you will have encountered so far. Unless it freezes, I would not recommend going any farther.
I should be going back in around the 3rd of 4th. Dependant on wheather it freezes or not. I have a Game Board Advisory Commitee meeting the 12th of October in Fairbanks, and will have to come out before that. I will be staying in the old log cabin at the second river.
I am not going to do any Moose hunting till November. I got drawn for the Muzzleloader hunt. I'll be in there watching over gut piles.
