Going through Lake Minnewanka, they eventually reached where the Spray and Bow rivers meet. Following the course of the Spray River valley, the intrepid British colonists then trekked along a tributary, Whiteman's Creek. From here they crossed the Great Divide of the Rocky Mountains, by a new route which became known as Whiteman's Pass. From the summit, they traveled southwest down the Cross River to its junction with the Kootenay River. They entered the upper Columbia River basin via Sinclair Pass, near present-day Radium Hot Springs. From there they journeyed south-west down to Lake Pend'Oreille, then on to an old fort known as Spokane House, then to Fort Colvile. When they arrived at Fort Vancouver, they numbered 21 families of 116 people.
