Vlad and I have quickly rushed to the location of the crash. We are adding in, with available compatible sources, new details to the crash zone in order to help people who use OpenStreetMap know more about the area, and to advise of any features and landforms that may affect the search and rescue in the next few days.
Please join in to help us.
Our thoughts are for the friends and family of all those on board Germanwings flight 9525.

You effort for providing useful information is meritorious but may i suggest you somewhat more carefully verify what you map. Aerial images are often difficult to interpret, especially if you don’t know the area from first hand experience and this is further aggrevated in mountain areas by irritating shadows and the distortions resulting from orthorectification.
are clearly wrong (the glacier has mostly vanished except for a small rock glacier and the cliff would have a stream flowing uphill across it).

The glacier came from Vlad and I checked the cliff in question. I do get inspired by the work of HOT (the humanitarian mapping people) because there are many areas in the world that are not mapped and the default imagery in Potlatch is detailed enough to create starting points for projects in future.
I do my best in good faith to add information to a very remote area that clearly lacked sufficient detail prior to the crash, but to have more people joining in will help rescue and medical teams anywhere, as the response to the Ebola crisis shows.
No one should be discouraged from giving crisis response mapping a try.

For the “Glacier de la Blanche” I did some research on the net and found a article on wikipedia stating in french : “La combe formée dans le versant nord du massif, sous le sommet, est recouverte par le glacier de la Blanche, actuellement réduit à l’état de glacier rocheux.” http://fr.wikipedia.org/wiki/T%C3%AAte_de_l%27Estrop . It says that indeed this glacier is no more made of ice and snow but it’s now a “rocky glacier”, maybe this can be mapped in OSM ?

Amaroussi, I fully agree with you about mapping some locations that got focus when the area lacks many features that are available in the OSM compatble sources, in the hope that it would be useful.

Rock glaciers are mapped with natural=glacier + glacier:type=rock - see http://wiki.openstreetmap.org/wiki/Proposed_features/Glaciers_tags
They are difficult to map though since they often look similar to scree and moraines in images.
