Thanks for getting the map out Scott.
Dennis, that is some very great boating water, but you have to find the right window. Quite a bit has been said about the sections Spring Bar to Corn Cr. so I will hit on some points about the section from Corn Cr. to North Fork.
You have got to have water. Ideally 7k and up on the Shoup gauge which is 14k and up at Corn Cr. Why? Because there are some real obstacles. Kitchen Cr. and Cramer Cr. can be some real butt kickers at any flow but need water to sneek the best you can. The section from Panther Cr. to Pine Cr. is 7 miles of rapids in a very narrow canyon littered with BIG ROCKS. Linda and I refer to it as "The Gauntlet". One seems to be close to oxygen deprivation by the time you get it run. Damn is it fun, the floater crowd always show signs of shock to see a jet boat going up
Pine Cr. to North Fork is a pleasant journey, a couple of ledges to negotiate but gives one time to get the heart rate back down.
Linda and I took up on an invitation from Jason W. to join them last Memorial week-end. River was 10k to 11k at Shoup and 20k at Corn Cr. What a great time. That puts the Whitebird gauge at around 45k. Good luck with Chitum at that flow
A couple of week-ends after Memorial, Lee and Abby joined us and we run Corn Cr. to North Fork, flow was around 16k at Corn Cr. as I remember, close to perfect. I have a few pictures kicking around somewhere, I will dig them out and post them in a few days.
We plan on being there this coming Memorial week-end this coming year and would welcome all who want to join us, you will have a ball.
