Altitudes of Nepalese Peaks. The reader will notice that many of the altitudes of Nepalese peaks are different from what had previously been accepted. The new altitudes are those given the Editor by Dr. Harka Gurung and are based on the latest available maps. Dr. Gurung states: “The principal source was the Survey of India topographic sheets at a scale of one inch to the mile (1:63,360). The other important aid was the set of maps prepared for the Sino-Nepal Boundary Agreement of 1979. The latter series includes 57 area maps at a scale of 1:50,000 extending four to five kilometers on either side of the boundary line. For areas not covered by the Sino-Nepal border maps nor the one-inch maps, peak heights are based on Survey of India topographic maps at Quarter Inch (1:253,350) scale.”
