Hi,
Mountain areas are composed by fell, scree and rocks. In the Forum are many users interested in hiking, but disappointed - as me - that none of these tags are rendered by any renderer.

So my request is to render fell, scree and bare_rocks (the last a proposed feature), to respond for the needs of mapping in higher mountains.

natural=scree may be used to denote shingle and pebble areas in large rivers (specifically in the area of Pakistan subject to flooding now (August 2010): and an 'emergency' patch render of this feature may be required.

Light experimentation suggests that rendering scree in a manner similar to landuse=quarry produces reasonable results. See http://www.flickr.com/photos/43047002@N06/4916378307/ (Champoluc area) and http://www.flickr.com/photos/43047002@N06/4917149322 (Passo Salati) both in Val d'Aosta region of Italian Alps.

Additionally for rivers already tagged with natural=scree see http://www.flickr.com/photos/43047002@N06/4916724316 (Philippines 2009 flood area).

Each of the Flickr images has at least one link to an OSM object located in the image.

These were created by adding the following immediately following landuse=quarry:

    <Rule>
        <Filter>([natural]='scree')</Filter>
        <MaxScaleDenominator>400000</MaxScaleDenominator>
        <PolygonPatternSymbolizer file="./symbols/scree2.png" type="png"    width="30" height="30"></PolygonPatternSymbolizer>
        <LineSymbolizer>
            <CssParameter name="stroke">rgb(128,128,128)</CssParameter>
            <CssParameter name="stroke-width">0.5</CssParameter>
        </LineSymbolizer>
    </Rule>

and adding ",'scree' to a clause in the leisure layer:

      or "natural" in ('field','beach','heath','mud','wood','scree')

scree2.png is a version of quarry2.png with the letter q obscured and random darker dots of variable size added.

I would support the solution of this render problem.

I'm looking forward for the rendering of "natural=fell" and "natural=scree", too.
The realization seems to be trivial (equivalent to "natural=wood") without any conflict.

This ticket was opened 7 months(!) ago, so I would like to know, what is the problem and/or where can I help to realize this request.

Very old and still open issue. IS anyone interested in solving it?

Discussions about a more accurate scheme for mapping glaciers renews interest on rendering screes. Please see Talk:Proposed_features/Glaciers_tags on the OSM wiki for more details.

This is now being discussed on Github: gravitystorm/openstreetmap-carto#545
Therefore, I will close the issue here.
