The slopes leading up to the pass, near Mount Forget (not named at that time), were blue with forget-me-nots when Mary Lenore Jobe Akeley [1878–1966] and Donald “Curly” Phillips [1884–1938] came through in 1914 on their way to Mount Kitchi (Mount Sir Alexander).

Before us stretched out a great alpine basin, probably fifteen square miles in area, presenting a wonderful vista of soft, sweet alpine grass, multi-colored alpine flowers, and low-growing balsams. Two miles beyond Eagle Pass we crossed a tributary of the ‘West’ Branch of the Little Smoky. Two miles beyond this stream we came to what seemed an easy pass-at 6,500 feet. As the other side proved to be only cliff, scree and rock-fall, we turned west, crossed two more alpine summits in four miles. The latter, at 6,400 feet, was snow filled, while the slopes leading up to this pass were blue with forget-me-nots. Below Forget-me-not Pass, we had four hours of maddening trail cutting down a rhododendron descent of 1,500 feet, so steep that the pack horses trod constantly upon each others tails.

Forgetmenot Mountain adopted in 1965 on 93H, not “Myosotis Mountain” as labelled on 1929 survey plan 10T264, McGregor River Area, drawn by Alan John Campbell [1882–1967], assistant surveyor to Arthur Oliver Wheeler [1860–1945] on the Alberta-British Columbia Boundary Commission.

“Myosotis Montain” was named by Campbell in association with Forgetmenot Pass and Forgetmenot Creek, in turn used by boundary surveyors in 1925 because of the abundance of flowers in the pass. Myosotis (literally ‘mouse ear’ ) is a large genus of herbs. Myosotis palustris is the common Forget-me-not.

Mary Lenore Jobe Akeley [1878–1966] and Donald “Curly” Phillips [1884–1938] came through this area in 1914 on their way to Mount Kitchi (Mount Sir Alexander).

After searching for hours for a camp ground and feed for our horses, we came at last upon a beautifully clear stream — another branch of the Little Smoky — and pitched our tents on an old Indian camp ground. The tepee poles were grass grown and rotten, left there years before doubtless by roving Crees who had come in from Grand Cache by the Muddy Water river. We called this stream Forget-me-not Creek, as it drains Forget-me-not Pass. It was reached, moreover, after a memorable day of hard trail work.

The “Little Smoky” is the Morkill. Forgetmenot Creek was previously recorded as the North Fork of Morkill River.

Adopted in 1965 as labelled on BC Lands map 3H, 1914 et seq, and as identified in the 1930 BC Gazetteer. “Fleet Creek (not Garnet Creek)” identified in the 1930 BC Gazetteer.

Named in association with Mount Fitzwilliam.

Origin of the name unknown.

The mileage does not in this case refer to the distance from the Yellowhead Pass along the railway.

W. S. Fetherstonhaugh, a divisional engineer with the Canadian Northern Railway in Calgary, surveyed in the area in 1906 and 1907. The feature was named by the Alberta-British Columbia Boundary Commission in 1923.

In October [1924], discussions [the Geographic Board of Canada] started regarding new names for the mountains on which the Geodetic Survey established stations. The mountain on which Lambart had a station named for his son, Arthur, was changed to Going Mountain, named for a Grand Trunk Pacific engineer who had worked in the area. Then it was changed to Fetherstonhaugh, named for another railway engineer who had worked in the area. Arthur soon received a third name change. “As Arthur peak is more outstanding than Boyd the Board would prefer that the name Côté [a senator from Edmonton] be applied to it and the name Fetherstonhaugh be transferred to Boyd.” A nearby pass was also named Fetherstonhaugh.
