Peruvian Andes
As you can probably tell, this map is heavily based on the Peruvian Andes. For the screenshot, I’ve used the Alps Dolomites map theme to get the snowcap, but the map obviously works without it.
Snow = Oil
There is no shipping access on the map, and only one highway and one rail connection. Most of the terrain is challenging, but there is some fairly flat space on which you can build a fairly sizable city. I do recommend 81 tiles for this. The starting tile has very little water, so be careful with where you place your pumps and sewage.
