Grand Teton, Winter Ascents on North Face and North Ridge. In February, I skied in and climbed the chimney system on the North Face of the Grand Teton which ends between the Molar and the Second Tower. I did not go on further because of unstable snow on the east ridge snowfield. From January 3 to 6, 1985 Jack Tackle and I made the second winter ascent of the North Ridge. We spent the first night on the Lower Saddle, reached the Grandstand via the Valhalla traverse and spent the second night atop the Grandstand. We climbed to the second ledge the following day and bivouacked around on the west face. The final day we reached the top and descended to the valley.
