Sounds like a definition set by politicians. :)
I can think of a number of areas in the US west that would count as mountains by that definition if approached from one direction but not the other. Mogollon Rim for one: http://en.wikipedia.org/wiki/Mogollon_Rim

> well, wikipedia says: "Deserts generally receive less than 250 millimetres (10 in) of rain (precipitation) each year. Semideserts or steppes are regions which receive between 250 millimetres (10 in) and 400 to 500 millimetres (16 to 20 in)." and states that the biggest desert on earth is the antarctic desert (quite different setting from what one usually thinks about by the term desert, isn't it?)
