Can anyone point me to a quick table showing the relationship between steam pressure and temperature at one mile above sea level?

@DanHolohan That is a good one, I'll save it to the library.
@SeanBeans Here are a few more. The air density chart will keep you out of trouble running the numbers for forced air heating an cooling. The gas deration is a must if you size gas lines or clock gas meters."If you can't explain it simply, you don't understand it well enough"

I was taught to use "absolute" pressure when using steam tables. Here are ambient pressures at various altitudes.
Sea Level = 14.7 PSI
5000 feet = 12.2 PSI
6000 feet = 11.8 PSI
7000 feet = 11.3 PSI
8000 feet = 10.9 PSI
9000 feet = 10.5 PSI
10000 feet = 10.1 PSI
Read you "gauge" pressure for steam and add the "ambient" pressure to arrive at your "absolute" pressure. Then read your steam table using the "absolute" pressure.
Also attached is approximate water temperatures at different altitudes above sea level.
Interesting stuff.
I hope this helps.

Was standing in front of 30-110psi..was a bit unnerving.
Steam kettles were sitting at 30 and pressure reliefs were rated at 350
