I know one can name points, which is used in naming places, hamlets, etc. Is there a way to specify a name for a valley, or a mountain ridge, which usually extend for a few kilometers. In printed maps, these usually show up a long, spaced names along the running of the valley. compare https://www.openstreetmap.org/?lat=46.8674&lon=11.7551&zoom=12&layers=M (the original) versus this mockup: http://yfrog.com/03valleynamesp asked 18 Oct '10, 23:06  Alexander Ro... edited 19 Oct '10, 00:01  Andy Allan |

There is 2 points in your question. 1 - Tagging - How tag natural region area ? There is not tagging schema yet. Some old proposals are available, but no really in use : This kind of place are often fuzzy. 2 - Map display Display problem depends on renderer, there is many renderer and many way to do this job.

I have been asking myself about this too as it's interesting for watersheds (maybe someday mapping of watersheds and natural landforms will be well integrated to OSM). The tags answered 12 Jun '18, 18:31  Privatemajory |
I have been using natural=ridge and natural=valley along with name=* to map ridges and valleys/canyons.
Not sure what renderers are picking that up, but the maps that I make for myself render ways tagged that way.
