Alps is probably the only real "mogging" of the US (and things like the Himalayas, etc) - we have "one" real impressive mountain range and it has an entirely different feel, being relatively isolated from humans.

Europe and Asia have had tens of thousands of years to make alpine mountains inhabitable, and it shows.

But outside of that, the US has amazing diversity partially because it's basically an entire continent, but also because of an accident of settlement and weather patterns that large swaths of the west were available to preserve.

There was an article recently about how in the UK it's all about restoration because everything is or was inhabited, but in the US it's about preservation because so much was simply never developed at all.
