History
Between 1973 and 1980, David Sherstone was employed by Environment Canada to study river ice break-up on the Mackenzie and Liard rivers. Much of the work was connected to the scientific studies supporting th initial Mackenzie River Pipeline Project. To conduct his duties, he travelled extensively to northern communities including Yellowknife, Fort Simpson, Fort Liard, Fort Good Hope, Fort Wrigley, Inuvik and Frobisher Bay [Iqaluit]. He also worked in conjuction with the Hay River emergency committee to deal with spring break-up and flooding. Part of this work was to develop an electronic ice depth monitoring guage which did not require ice drilling and allowed rapid reading. While doing this work Sherstone documented his travels with photography, and took pictures of communities, unique buildlings and landmarks, transport vehicles, and natural phenomena related to his career.
