UPDATE

Actually, I checked the picture more closely by enlarging it. I believe the words on the left post (above the word Alberta) reads Kicking Horse Pass.

The picture shows the road through the Kicking Horse Pass before it officially became Highway # 1 between Alberta & British Columbia. The road followed the same route as the Canadian Pacific Railway which was completed in 1885.

See the following site for a little background.
