Entering into a narrow gorge

Once I felt that I have entered into a narrow gorge which seems to have no end. I could see no point in turning back, I decided to walk steadily ahead, till I found the opening at the other end of the tunnel.

In this image, I had a view from the top of a very narrow gorge (pass), with tall, rocky sides of adjoining mountains on both sides (brown mixed with blue, black and purple vertical strokes). At the center of the image is a small lane, filled with burning coals, the visibility was poor. I could feel that my therapist is walking by my side, sometimes on right, sometimes on left and hasn't left me stranded alone (yellow).
