I was trying to reach the summit of Quien Sabe Peak but got a late start from Spur Cross Park (11:30). I came up trail #248 from the west side but by the time I managed to follow the trail all the way across Skull Mesa to where it goes down on the east side it was too late to go to the summit of Quien Sabe. From the top of Skull Mesa to there is extremely hard to follow. I lost the trail many times and wasn't really sure I had found it until it started down just past the fence. I didn't actually hit the highest point of Skull Mesa either because I was trying to save enough time for Quien Sabe. I did go back 2 days later and summited it but went up and down the trail on the east side.
