Following takeoff on the return leg of a cross-country flight, the pilot flew directly up a valley, which required the aircraft to climb from the airport altitude of 7,815 feet to clear a pass 12,095 feet high in 19 miles. The temperature was 20 degrees above standard and the distance to climb was calculated from the performance section of the flight manual to be 28.6 miles. The pilot flew up the center of the valley and when the terrain out climbed the aircraft, she had insufficient space to do a reversal. A witnessed forced landing was made on the side of a mountain, above timberline, at 11,948 feet elevation. The upslope was 19 degrees and the side slope was 7 degrees. The terrain was rough and rocky. CAUSE: the pilot's improper decision to fly directly up the center of the valley and not circle climb to gain sufficient terrain clearance altitude. A factor was inadequate route performance planning by the pilot.
