- There's *nothing* that OpenStreetMap can do here.
- You'll have to notify the CyclOSM folks at https://github.com/cyclosm/cyclosm-cartocss-style about the issue with the digital elevation model here, I do not know where they get the elevation data from. The swisstopo DTM shows *no* crater here: https://pasteimg.com/image/zmMOV
- There's *no* activity on Strava Heatmap here: https://www.strava.com/maps/global-heatmap?sport=All&style=dark&terrain=false&labels=true&poi=true&cPhotos=true&3d=false&gColor=blue&gOpacity=100#13.62/46.4995/8.56896, so I wonder about the "other maps" and "report it with a mistake", honestly.
