Totalabuse, you are right in saying Jemima is ever changing depending on erosion and guys tearing it up with lots of wheelspin.
Right now I would say there are 4 trails up. One way off to the left by itself, which used to be bad at the top but is now pretty easy, and 3 on the front face of the hill. The ones on the right and left are moderate, and the one up the center (in the video) is the hardest and needs a locker/or electronic traction control (at least as of 3 or 4 weeks ago). I was surprised how much the center hill had changed due to erosion. I was on 3 wheels almost the whole way up.
We just checked out top of the world Sunday. It was interesting, but I am thinking of another similar area over by Buckeye for the end of the day as it has hills, gullys, a big water pit, and lots of space for everyone to hang out, bullshit, and play around. I really don't want to make this too hard, as I would like anyone who wants to come out to feel welcome and have fun regardless of what they drive. Wives/girlfriends are also welcome. If mine is free she will come along and take pictures.
HERE are some she took back in February.
I wouldn't consider myself "hardcore" by any means either. I am running a 08 FJ with 33s, a factory rear locker, and it is my daily driver so I REALLY don't want to get the interior wet
