hey summit crew -- just outside the county there is a short stout creek run with significantly more "character" than both the snake & 10-mile. it's not everyone's cup of tea, & as far as i know it hasn't been run in a couple years. middle fk. south platte near hoosier pass. coming from breck, go over hoosier & take a right on a dirt road just past the summit. follow it to montgomery reservoir & then drive to the back of the lake, park, & hike your boat up past the old mining bldgs. cross the creek in the flats above the first waterfall, then situate for put-in in an eddy on river-right. peel out & boof the first 15-footer. it's super steep & non-stop from there. 4 long-ish rapids: "lapdance", "double anal", "luv u long time", & "dirty sanchez". dirty sanchez, the last little mini-gorge, hasn't been run as far as i know -- we never saw it w/ enough flow to cover up some skanky rock. the rest of the creek is surprisingly clean with nice granite & you can run laps on it. it's kind of "novelty boating", but summit county is kinda "novelty livin'", ain't it? makes for a nice sidetrip on the way to the ark ..
the gauge can be found online on the DWR site under upper middle south platte near alma. you'll want around a hundred to make it worthwhile ...
