History
The mountain is named kał-ka-č’ałḥ (Kulth-ka-choolth) meaning Jagged Points Facing Upward in the Tseshaht Nuu-chah-nulth languages.
The first recorded ascent by colonists was made by botanist John Macoun in 1887 led by local Indigenous guide Qualicum Tom and his son James Thomas. Macoun was a botanist to the Geological Survey of Canada. Mount Waddington was first seen from the peak of Mount Arrowsmith by Don and Phyllis Munday in 1925 (see also Mount Munday). The mountain was named about 1853 by Captain Richards for cartographers, Aaron Arrowsmith and his nephew John Arrowsmith.

Biogeoclimatic zones
Mount Arrowsmith has three main biogeoclimatic zones. On the windward, wetter west-facing slopes the Coastal Western Hemlock zone occurs up to 1,050 m (3,440 ft), where it grades into the Mountain Hemlock zone. This forms a continuous forest up to 1,300 m (4,270 ft); above is a parkland phase which grades into the Alpine Tundra zone at 1,600 m (5,250 ft). The leeward, east-facing slopes are warmer thanks to more sunshine, and all zone boundaries are higher by 50 m (160 ft).
