we did yule 4 years ago and i still remember it as one of the best days of creeking i have ever had. we had no beta and did some limited scouting [after a minor altercation with a landowner]. he told us it was all private on both sides and to stay away. we politely said okay and drove on up the yule road a ways and bushwhacked down to the creek with some gear in case we had to climb out [i think we went a little ways past a bible-camp-type place] we were immediatly upon some class 5 in a beatiful, tight canyon. the drops just kept coming, and we took turns probing them. water was not too high so we were able to get out above almost all drops. when we got to the final 4--we were shocked and amazed. with no beta--we considered climbing out, but did not. one of my friends ran the 35 footer 1st, and we all regrouped in the pool below it and wall-slammer. we knew that once we ran the 35--we were committed to the wall. i took this one 1st and cleanly lifted the left side of my boat for impact. it was very hard to say the least. my buddy got the wind knocked out of him pretty bad. you hit that wall going so fast. after wall-slammer it was my other pals turn at going 1st and i was glad about that. this 3rd drop of the final 4 is so sick---drop into the "v" slot and catch air coming out of it and then land with another 50-65 feet of verticle at about 45degrees and then hit the water so fast that i actually caught big air on the bounce. then the sloppy 15-18 footer to end it. the 3 of us in that bottom pool looking up at what we had just run were as stoked as any boaters could be. that night we drank and relived and drank and relived until 2 of us puked. this did not help us the next day on the crystal gorge. as far as yule goes---i have to say that the big 4 did not require much technical paddling skill, but the consequences could have been horrendous [decapitation, broken bodies] vallecito requires more skill in my opinion. does anyone know the gradient of the last half mile or so?
