The real mountain (perhaps only partially) climbed by Douglas on the westside of the pass retains the name Mount Brown but is only high. The name Mount Hooker, the name given by Douglass to a summit a little to the southward and nearly the same height, was given to a peak 9 km ENE of Mount Brown and in height. It was only climbed in 1924, nearly a century after Douglass' visit of Mount Brown. The mountain Douglass named Mount Hooker more likely is McGillivray Ridge (or Rock) (), which had been named years before Douglass crossed the Athabaska Pass.
