Thanks to all who responded to my problem, notably the following:
1) Brain Russo:
.hgt files are from the SRTM mission.
3DEM can open them and turn them into a USGS DEM, etc.
3D Nature has a tool that's good for patching small holes.

For big holes you'll need to merge in other data (GLOBE/VMAP
contours/dted/etc..). There're a variety of other tools, google around
for 'srtm tool' or 'srtm conversion', etc etc.
2) Dan CRACIUN:

You can import .hgt files directly and then export them as geotiffs
3) GRAEME BROOKE:
Apparently MicroDEM can read HGT files. This is new to me - I need to update
the Grime Site (www.grime.net/gistools)! It seems the link on Grime to
MicroDEM is broken too! To get MicroDEM, try
