I wanted to create a landscape that resembled southern California, with abrupt craggy ridges separating valleys like in Los Angeles. I did not put the city near the ocean, however, since I already have a large city running on a coastline setting and wanted to try something different. Instead, I carved a winding river and several tributaries, which will afford the opportunity to experiment more with NAM bridges as I continue to learn the ins and outs. I also raised the land on the north side of the river to allow tunnels to work properly and not strike sea level under ground.
