If your goal is realistic topography, remember that mountain chains look like long fused ridges at continental scales. The occasional lone mountain is okay it’s probably a volcano or the central peak inside a mountain-ringed impact crater. A few ranges of lone hills (old, worn out mountain ranges) are a good idea. On land, their foothills should be visible: scatter a few hills here and there at the margins of the mountains. If you’ve already drawn your coastlines, extend the mountain chains past them, forming peninsulas and island chains. * Hill country, worn plateaus, badlands, and other rugged-but-not-mountainous terrain is typically the eroded remains of ancient, “dead” mountains. Lone mountains are rare and almost always volcanic in origin.
If the crater is big enough and the world is Earth-like, it will likely be a lake or sea.Īll four of these methods form chains, ridges, long plateaus, or rings. Sometimes an impact crater boasts a second ring or lone peak at the center of the crater. Impacts between planets and asteroids form circular rings of mountains.These eventually form chains of mountains as the plate slowly moves over the hotspot. Plates burning themselves as they migrate over mantle plumes * deep in the planet can also give rise to volcano-blisters.Volcanoes are formed from the recycled remnants of the bottom plate. Volcanic mountains can form near the edge of the top plate during this long, slow collision.Even when one plate slides beneath the other, the friction and pressure send mountains shooting upward. The surface crumples upward where the plates collide. Most mountains are the children of lusty continental plates, birthed from scandalous collisions between landmasses too attracted to each other for their own good.
They take their shape from their creation: * Mountains back each other up and form chains, ranges, and ridges. Unless you already know the exact shape of your continent or island, sketch your mountains before your coastlines. Mountains are the skeletal system of your world. If you’re building a sizable chunk of continent on an Earth-like world, * you’re going to need to keep geology in mind. But some mapping concerns go beyond mere aesthetics. Building a map for a fantasy setting involves a lot of details – most of them fun! Art styles, fonts, and icons need to be chosen.
