I found this website while looking for a little creek I had hiked down a long time ago. I vaguely remember a week long trip, starting at little yosemite valley. My boyfriend at the time and I decided to take a "cross country" trip down what I remember the map called "no return creek". It was only about 15-20 miles, but.....Wow. What an adventure. What I remember is emerging from our "adventure" at the merced river, but maybe it was the touloume...and maybe it was called return creek and we nick named it no return. Water was a problem, because the banks of the river were so steep...big boulders...so hard to get down. Bivowacked (?sp) a couple of nocs, staking in sleeping bags so they wouldnt slip into the river, LOL. My boyfriend fell and sprained his ankle mid way...thru a "chimney". I smashed my nose, fording the river....All in all, a good time was had by all, LOL. Your post is over 1 year old...so maybe you will never read this. But, if anyone has ever heard of this little "detour" please write. I have been thinking about going back and carefully retreading my course, LOL.
