Map I created for Age of Steam based on the Pacific Northwest. Lots of mountainous areas and impassable peaks.
This has not received any play testing yet, so bare that in mind before printing it out or anything. I did try to make a map that was interesting and balanced and I will try to update it with suggestions if anybody is interested in trying it. Also if you just like the idea you are welcome to take my idea and make a new/improved/better version and upload it yourself.
I haven't tried the western US map yet personally but I think this map might benefit by something similar to the transcontinental link from that map.
