Henry Youle Hind (1 June 1823 – 8 August 1908) was a Canadian geologist and explorer. He was born in Nottingham, England, and immigrated to Canada, settling in Toronto, Ontario, in 1846. Hind led expeditions to explore the Canadian prairies in 1857 and 1858. In 1857, he explored the Red and Assiniboine River valleys, and in 1858, the Assiniboine, Souris, Qu'Appelle, and South Saskatchewan River valleys. The expeditions are described in his reports Narrative of the Canadian Red River Exploring Expedition of 1857 and Reports of Progress on the Assiniboine and Saskatchewan Exploring Expedition. Hind's activities changed perceptions of the North West and helped open up the Canadian Prairies for agriculture settlement. Early life Henry Youle Hind was born in Nottingham, England.
