The range's name was conferred by Captain Richards after the 100-gun HMS Britannia, which saw action at the Battle of St. Vincent, 1797 and the Battle of Trafalgar, 1805. Mountains within the range allude to British royalty - Hanover and Windsor for the respective dynasties. The range includes Sky Pilot Mountain, a horn-shaped summit prominently visible to southbound traffic on BC Highway 99 on the descent from Whistler to Squamish.
