At one point the track divided into three and narrowed, and Allen climbed a tree to see where they were.

The track narrowed as it left the ford, becoming little more than a dusty trail through dense stands of pine and alder on either side.

The track soon narrowed to a small wagon road, and after this to a footpath through the forest, which sloped upwards before us.

And another... The track narrowed, twisting deeper between the trees.
