Mount Logan. A scientific expedition led by D.P. Jones and me operated out of a geodesic dome shelter erected on the northwest col in July. The work is connected with a proposed ice core drilling operation in 1979. See Canadian Alpine Journal 1979 for more details. The King Trench route was used for the ascent which took 15 days. On July 16, A.R. Jones, R.W. Orvig and D. Verrall climbed the West Peak (5915 m) returning to the Col (5360 m) the same day. On July 18,I was flown off the plateau in the Arctic Institute’s HelioCourier and the rest of the party were flown out of the Trench on July 28.
