In 1968, members of The Fort Garry Horse (Regular) were tasked by the RCAC Corps Commandant, MGen B.F. McDonald, DSO, CD to make an ascent of Mount Worthington, Yukon Territory. The mountain had recently been named in honour of the late MGen F.F. Worthington CB, MC, MM, founder of the Corps. The intent was to climb the mountain on behalf of the Corps, photograph the event, and leave a suitable marker at the summit.

RHQ troop, led by LCol G.J. Martin CD, travelled to Banff in May of 1969 for a week of mountain ops training and flew to Whitehorse on 7 June. The mountain was to be climbed on the 9th, followed by a road move using the RHQ vehicles back to Calgary.
