"Mountain probably climbed by early goat hunters. First recorded ascent 16 August 1908 by BC Mountaineering Club party: William Gray, Fred Mills, G. Harrower, Frank Harold Smith. Three peaks on the Mount Seymour massif were explored, [this] last being nicknamed Third Pump Peak from Smith's remark that a storm-riven stump near the summit looked like a pump."
