A Canadian explorer, author and Royal Canadian Geographical Society President and CEO John Geiger is making a Calgary appearance Thursday night to promote his latest book. Quest: Shackleton’s Last Ship and the End of the Heroic Age tells the story of the discovery the Quest, the last ship of Antarctic explorer Sir Ernest Shackleton, in the Labrador Sea, and subsequent expeditions to survey the wrecks of Quest and Terra Nova, the final ship of Capt. Robert Falcon Scott. Geiger led the 2024 expedition that discovered Quest, then returned in 2026 with a Royal Canadian Geographical Society team and members of the Woods Hole Oceanographic Insitute to survey both wrecks. The expeditions blended maritime history, modern exploration and advanced marine technology to tell the story of two ships that played huge roles in the history of polar exploration. Geiger, who grew up in Edmonton and graduated from U of A, is launching his eighth book at 6:30 p.m. at The Next Page Bookstore at 127A 9 Ave. S.E. in Inglewood.
