Jobe was an accomplished mountain climber and was a member of the Alpine Club of Canada (ACC) and the American Alpine Club. From 1905 to 1918 she made ten expeditions to the Canadian Rockies. In 1913, she left her teaching job at Hunter to undertake an ethnographic expedition to study and photograph the Gitksan and Carrier Indians living between the Skeena River and the Peace River.: Jobe concluded the summer of 1913 by meeting up with the annual camp of the ACC. There she heard of a distant mountain northwest of Mount Robson that had been glimpsed by members Samuel Prescott Fay and Donald 'Curly' Philips.: In 1914, she returned to the Canadian Rockies in search of the mountain, hiring Philips as her guide. At the time, Jobe called their destination Big Ice Mountain, but in her later reports she referred to the peak as Mount Kitchi (from a Cree word meaning mighty:); the mountain was officially named Mount Sir Alexander in 1916. Joining Jobe and Philips on the expedition were Margaret Springate and Philips's assistant (and brother-in-law), Bert Wilkins.
