North America, Canada, Rocky Mountains: Elevations in the Maligne Lake Area

Rocky Mountains: Elevations in the Maligne Lake Area. A new edition (1942) of the Jasper Park South Sheet (3 mi. to 1 in.) is now available, with the notable addition of contours and elevations E. and N. of Maligne Pass to the park boundary and the railroad. For the first time official figures are given for the peaks surrounding Maligne Lake, and elevations must now be revised upward, as follows: Mt. Brazeau (11,386 ft.) ; Mt. Henry MacLeod (10,789 ft.); Mt. Unwin (10,723 ft.); Mt. Charlton (10,554 ft.); Monkhead (10,535 ft.); Mt. Mary Vaux (10,502 ft.); Maligne Mtn. (10,475 ft.); Coronet Mtn. (10,340 ft.); Llysfran Pk. (10,304 ft.); Samson Pk. (10,808 ft.); Leah Pk. (9191 ft.) ; Replica Pk. (9167 ft).

No elevations are given for Mt. Warren or Valad Pk., but from contour intervals one finds them to exceed 10,800 ft. and 10,600 ft., respectively. An unnamed summit 3 miles E. of Maligne Mtn. is assigned an elevation of 10,176 ft. Three miles S.S.E. of this, and almost due E. of the head of Maligne Lake, is the shale mountain contouring 10,100 ft. ascended under the name of “Mt. Southesk” by the party of D. M. Woods in 1930 (Mazama, XII, 72). The Mt. Southesk of the new map is just above 10,200 ft. by contour, and, being much too far for a round trip in one day from Maligne Lake, must be regarded as unclimbed unless future evidence to the contrary is revealed.

Another unnamed peak, 4 miles N. E. of Maligne Mtn. and forming the N. buttress of a pass between the heads of Rocky and Southesk Rivers, rises to 10,277 ft.

In transference of names, the peak in the Climber’s Guide called Monkhead (Thumb) is now Mt. Paul, its contour elevation being just above 9200 ft., while the name Monkhead is given to the loftier summit (10,535 ft.) N. W. of Mt. Warren.

An unnamed double-peak 5 miles E. of Mt. Warren has summits of 10,400 ft. (N.) and 10,200 ft. (S.). A Crestline some 6 miles long continues S. E. from this, bearing summits 10,000 ft., 10,000 ft., 10,200 ft., 10,400 ft. and 10,000 ft., the last being 5 miles N. W. of Chocolate Mtn. and the source of Isaac Creek. All of these rise E. of the stream draining the Brazeau glaciers to Brazeau Lake.

The most important unnamed peak in the terminal forks of Southesk River is 10,600 ft. and rises 5 miles S. E. of Southesk Lake. A peak of 10,200 ft. culminates the uplift between the main source of Southesk River and Isaac Creek.

An unnamed peak of 10,000 ft. rises between the highway and Maligne River, in the E. angle between Ranger Creek and Atha- baska River. It can undoubtedly be ascended from the road.

There are a number of small lakes at the sources of Rocky and Southesk Rivers, while the glaciation of Maligne Mtn. and lesser summits northwestward along the local watershed between Maligne Lake and Rocky River is greater than recognized hitherto.

From this it is now evident that the Maligne peaks form the most important alpine area E. of the main watershed, and there is at least one good season’s work to be done on unclimbed mountains near the S. E. end of Maligne Lake.
