Locals call it simply "The Gap" -- a perfectly descriptive name for this deep breach in the massif of the Livingstone Range that constitutes the sharply rising eastern wall of the Canadian Rockies in Alberta.
Because the breach itself runs parallel to the mountain spine , the Livingstone Gap is invisible until you are actually upon it.
The Livingstone Gap drains the north-south valley bounded on the east by the Livingstone Range and on the west by the High Rock Ranges, whose ridgeline defines the Continental Divide, and the Alberta-British Columbia Provincial Boundary.
Rivers and streams combine just west of The Gap into the Oldman River, which gushes through the high, narrow canyon into rolling foothills and ranch country.
The Forestry Trunk Road 40 is closed in winter, so perforce the best seasons to penetrate Livingstone Gap are spring, summer and fall. Fishing the Oldman and its tributaries is best attempted from July 15 through the end of September because of stream volume and clarity.
