This can be done without surface data.
If you only have spline curve data of the topo you can follow that with most
CNC programs.
I cut a land property for a client and only had spline curves to use from
AutoCAD.
With my CNC software (WorkNC) I used "on curve machining" and a ball end
mill just large enough to leave a small scallop.
I then blended the high points by hand and had my property. I did this in
about an hour with a soft foam board.
I'm sure the Rockies will be a little more detailed but the principle should
be the same.
Good Luck
Karsten A

It's not _that odd.
There's always the USGS DEM. They're 1/4 mi. squares, raster heights at 30m
spacing. The Z tends to be more accurate, mostly derived from 1:24k topo
quads. There are a few freeware ways to get from DEM to geometry. Start at
http://data.geocomm.com/. What's the output size? How much of the Rockies
do they want? How important is accuracy?

I have an odd request from a customer. They are wanting a 3D file of the
Rocky Mountains so that they can make a replica in RP and have it metal
plated.
So, any such things out there?
