the Geography of Knocksville and the surrounding area
Here is a map of Knocksville and the surrounding area:
The map shows the area around the Town, but it may need a little explanation.
The light brown is the valley bottom and the brown is the top. So Knocksville itself is situated on a 'stack' in the middle of death valley. To reach the rest of the world the residents must either take the bridge or one of the daily helicopter flights. The large metropolis of Carser city is the towns closest neighbour and only a half an hour drive away from knocksville.
