U.S. Lieutenant Frederick Schwatka (1849-1892) crossed the Chilkoot Pass and explored the Yukon River in 1883 under orders from General Nelson A. Miles and without notifying the Canadian government. His photographer and topographer, Pte. Charles A. Homan, made a rough survey of the course of the river. The work was incorporated into a map issued in 1885 by the U.S. Geological Service. This was the best map of the area until the Canadian Geological Service issued those made by George Dawson and William Ogilvie in 1888. Homan's photographs were reproduced as photo engravings in Schwatka's many publications. © Government of Yukon Heritage Branch 2001. All Rights Reserved
