Many varieties of mountains and hills, in the style of the Liberated Pixel Cup (LPC). Includes grassy varieties for most styles, and includes a snowy overlay for the whole map (i.e. all varieties have a snowy variation). 

Includes Tiled terrains for most styles and Tiled automapping files for many as well. Use the terrain tool to draw the cliff, then automap to draw the walls. I recommend you disable "Automap while drawing" and manually invoke automap periodically instead. 

Note 1: There is one complementary style of mountains that is referenced in the Tiled files but not in the image---it's based on "The mana world: Forest Tileset" <https://opengameart.org/content/the-mana-worldforest-tileset>, which is only licensed GPL v2; despite several efforts, we have been unable to contact the original authors and secure their permission for a different license. Since that license is not compatible with this one, that edit is included in a separate submission. But I'm not stopping you from downloading that submission and then pasting it on top of this one to make single image... 

Note 2: Preview images and tiled.zip contain content from my LPC Terrains submission. License and attribution requirements for that submission still apply.
