Mountain - a description
There is no overall agreed definition. The following "A large natural elevation of the earth's surface rising abruptly from the surrounding level; a large steep hill" [Oxford English Dictionary] appears to as good as any. The boundary between hill and mountain being suitably vague.
Some well known mountains:
- Mt Everest*, Nepal/China - 8,848m
- Mt Robson*, Canada - 3,954m
- Aoraki /Mt Cook, New Zealand - 3,724m
- Yr Wyddfa /Snowdon, Wales - 1,056m
* no universally agreed local name
The height of a mountain (in particular) attracts a lot of attention - but what does it mean? The height above sea level might be one answer - but the heigth of what point? relative to sea level where? and at what time? even "mean" sea levels are rarely static. The mountain itself only exists because lateral pressure has buckled the land and this process has raised a section up - and that process has not stopped.
Reference to the local geoidal surface is the only practical solution based on many observations resulting in an estimate. It is a relative distance.

Common on early coloured small scale maps - the tints indicate different levels of land above sea level. While effective at this scale/resolution of map the colours can conflict with other map features. The colour densities therefore have to be carefully chosen to minimise this problem.
