This mountain was named by James Hector [1834–1907] in 1859. The origin of the name is uncertain, although it is similar to the what Hector reported as the Native name for the wolverine,which he mentioned on his trip to Jasper House along the Athabasca River:

January 22nd [1859] — At noon to-day we halted to cache another bag of pemican, which we did by building logs over it, carefully fitting them together by notches. The great danger to a caché is from the wolverine, a small rough-haired animal, like a miniature bear, but much stronger in proportion to his size than any other animal in the country. He is posessed of great cunning also, and it is very difficult to defeat his marauding propensities. Their Indian name is ker-kes-shu, and many wonderful yarns are told about them round the camp fire. For instance, that a man once left his gun, with the leather cover on, leaning against a tree, while he went to skin a deer he had killed, on his return his gun was gone, and no trace of anything to be seen in the snow excepting the track of a wolverine, that seemed to have gone to where the gun had been left. Following the animal’s track, he found after more than 300 yards, the mark of his gun trailing in the snow as the animal had dragged it along, but for this distance it must have carried it clear of the ground, a matter of some difficulty to a little beast not higher than a fox.

This prominent mountain was named by James Hector [1834–1907] in 1859 after Tekarra, a local Iroquois hunter. Tekarra, along with Henry John Moberly [1835–1931], accompanied Hector on a journey toward Athabasca Pass in 1859.
