Frank,
All other factors normal, water boils at 199.3 F at 7000 ft.

I'm at 7200 ft (Laramie, WY) and my Thermopen usually shows about 194-5
degrees at at rolling boil, depending on the high or low that we're in
at the time.  It sounds like yours is reading low.  I'd think about
195-6 might be the right range for you.  
 
Actually, this calculator shows you might expect a slightly higher

To adjust your thermometer, just turn the nut with a wrench and you'll
see the needle and scale move in relation to each other.  Boiling water
is a good check point.

	Ok, I do have a quick question or two not related to your topic
here. I purchased the inexpensive (read "cheap"--that's me) $5.00
thermometer that Tom sells. I am curious if anyone can tell me how to
check its accuracy and if need be, calibrate it, inexpensively? I ask
this because, it shows a rolling water boiling at about 170-175* (the
head is so small, it is difficult to see the exact temperature. I should
have gotten the big head, but as I said before, I am cheap--guess I need
to get a magnifying glass?). I need to say that I am at 7000 feet, so
really have no idea if this is the right temperature or not.  
	 
	 thx, Frank

If a thermometer is off a few degrees, say 5 or so, its really no biggie 
to be honest... the boiling point of the water will have some things 
affect it too,  ie your altitude,  current weather conditions, 
dissolved  stuff / chemicals in it etc etc.
most cheap thermometers are only accurate to 2% to 5% anyways... so 2% 
of 200 degrees is up or down 4 degrees.
either way, a few degrees should not make that huge a difference in your 
coffee brewing all other things considered in the act of brewing..
