That's the trouble with rotors. Even when there is enough moisture
to show standing lenticular clouds over the peaks, you may have no
indication of where the rotor is on the downwind side of the range.

The only rotor I ever flew into was just after coming out of a pass
in the Alaska range. There were lenticulars over the peaks, so I knew
there would be rotors downwind. I underestimated how far from the
mountains the rotor would be. After flying about 10 miles out of the
pass, I felt it would be safe to make a right turn, parallel to the
mountain range. I was wrong and flew right into the rotor. I spent a
good 5 min. with very little control over my plane. It was a very
upleasant feeling. If that happened in IMC, I wouldn't give big odds
on getting out in one piece.
