As we transitioned to the summit, the trees gave way to low shrubs, rocks, and patches of snow.

Before there was a train, there was a foot trail that led over the summit to the gold fields of the Yukon. That trail was used in 1898.

A mountain lake had been formed by melting snow. This was the first of two small lakes and one large lake that we saw.

The forest on the Yukon side of the summit. This was the middle of three lakes.

Flags marked the border between the U.S. and Canada. Because we were not allowed to leave the train at the Yukon stop, we were never technically in Canada.

In the old days, the border was manned by members of the North West Mounted Police . First called the North West Mounted Rifles, the NWMP patrolled Canada's Northwest Territories .

The end of the train stopped and parked on the Canadian side of the Yukon . Notice, that at the correct angle, the lake appeared blue.
