"I took the spelling from G.M. Dawson's Geological Survey map (1879-80), in which he gives Beece as the alternative name for Anahim Peak. I cut this in while running the Parallel in 1912-13, and old Capoose of Abuntlet Lake told me some wonderful yarns about the way in which Indians used to come from far and near to get supplies of beece, or obsidian, for arrowheads and so forth. Anybody who came for obsidian was supposed to leave a piece of rock on a pile near by, and I understood this to be the pile I was sighting - see my account in the Lands Department Report for 1913. In 1923 I was working near the 53rd Parallel and climbed Beece, but did not have time to look for obsidian. I found that the mark I had been shooting at was not a pile of rocks, but a bush, and had to tell the joke against myself in the Report for that year." (11 April 1949 letter from R.P. Bishop, BCLS, file H.1 47).

"Bisqox" is the Tŝilhqot’in name for this lake and means “obsidian creek.” Two words "bis" (obsidian) and "yeqox" (river) merged over countless generations of usage into a single proper name (advice from Tŝilhqot’in National Government, 2023).
