Hello good people! First time poster here, I figured I would overcome shyness and share a map I quickly put together for an encounter in my current campaign:

The general idea was to create a difficult bottleneck situation to pass through. The adventurers are following the river from the south, walking upstream. The river progressively becomes a torrent, flowing in a gorge between steep cliffs. After a while, they reach an area where a waterfall has carved a small canyon. The water is treacherous, and reaching the upper cliff requires climbing some rough staircases carved in the stone, and crossing a rickety-looking hanging bridge. And of course, this would be a perfect spot for a patrol of goblins and hobgoblins to set camp…

Straight ink, dotted marks for alignment; might try an alternate version using some shading to highlight volume better.

Comments / questions / criticism very welcome
