From Chandragiri, the route descends south and exits the valley to continue on to India.

Moreover, at some point the ridge ends, so that the route must descend to ford a stream before rising again to follow the next ridge.

The route descends and passes the Moneygashel crossroads, where the remains of a sweat house may be found.

Now the route descended into a broad, deep cleft.

The route then descends and makes a traverse around to the opposite side of the peak, finally ascending the northwest slopes.

The route gradually descends back into the valley as it heads further northward into the town of Fleming.

From here the route and descends towards the city of Sheffield and its urban sprawl.

The route descended into a valley where a large river ran.

The route descends along the western bank of Lauzon Creek before turning southeast and crossing it.

These were required because the route of the ditch gradually descended along natural ridges so it could be built without requiring pumps to move the water.
