Reeve received a letter from Bradford Washburn in January 1937 asking if he could fly a party of climbers to the glacier at the base of Mount Lucania in Canada. Reeve agreed to undertake the task. In April, the bulk of the supplies were flown in. When he flew Washburn and Robert Bates to the site, the weather had turned unseasonably warm and the plane sank up to its belly in slush. It was over a week before Reeve could take off, after the temperature had dropped sufficiently for a crust of ice to form over the slush. The trip was described by Reeve as the most hazardous of his career, but he had set a new world record of for the highest landing on skis, more than higher than any in either the Arctic or Antarctic.
