The creek begins at Tyoax Pass, at the divide between the basins of the Bridge River and that of Big Creek, which is a tributary of the Chilcotin River. Its upper course flows east, then turns south and then southeast, entering a progressively deeper canyon until just northeast of Tyaughton Lake, which is connected to it by a short creek, and then turns east-southeast between Pearson Ridge (SW) and Marshall Ridge (NE) in a continuation of its canyon until it emerges as a side-inlet of Carpenter Lake which was formed by the creation of Carpenter Lake. That inlet is bridged at the mouth of that inlet by BC Highway 40, also known as the Lillooet-Gold Bridge Road or the Carpenter Lake Road. Before the lake's creation its outlet was at the lower side of the road, and it was bridged by the predecessor route, then known as the Bridge River Road.
