Yes. I did that when first beginning to learn HFTA. Each radial took about 
one half hour. N6BV, the program author, recently taught a Webinar showing 
how to import topographical data for locations around the world. I don't 
recall now whether it was NCCC or PVRC who hosted it. Chances are you can 
find a recording at one of those websites. Also, there is updated 
documentaion for HFTA at the ARRL website that should be used in place of 
what's on the CDROM. 

HFTA can handle any distance that you choose to enter. The limitation is the 
number of data points for each radial. So there would be no problem including 
that mountain in your analysis.
