Course
The Pelly rises in glaciers on the western slopes of the Selwyn Mountains above 1,400 metres (4,600 ft) in elevation, close to the Yukon-Northwest Territories boundary. It flows south and west through a wide valley, receiving many small tributaries from the east. It passes the Pelly Lakes, out of which flows the Woodside River, and there it turns to the west. The Pelly then assumes a northwesterly course through the Tintina Trench. It flows northwest to receive the Ross River at the town of Ross River. It then merges with the Lapie River from the left and passes the community of Faro, after which it runs south of Rose Mountain and receives the Glenlyon River from the left.
At the Glenlyon River confluence, the valley narrows and the walls grow higher and steeper, and a short distance later, receives the swift-flowing Tay River from the right. Several kilometers after, it turns north and receives the Earn River, also from the right. The river soon exits out of the canyon and winds across a plain, where it receives the Tummel River from the left. It then receives the Macmillan River, its largest tributary, from the right, then turns west, looping around the town of Pelly Crossing and crossing under the Klondike Highway, one of only two bridges on its course (the other is in Faro). The river continues west for about 25 kilometres (16 mi) to merge with the Yukon River near old Fort Selkirk.
