Denver

Air pressure is measured in different ways. Two common ones are PSI (pounds per square inch) or a barometer which measures in column inches of mercury. As we know the barometer goes up and down with weather so the air pressure goes up and down. The highest barometer reading ever recorded is about 32 inches or just over 15.6 PSI. The lowest barometer reading ever recorded was 25.69 in the middle of a hurricane so this is not typical but equates to about 12.5 PSI. These are all sea level readings. So we need an average, or normal. The standard is a barometer of 29.92 which equates to about 14.7 PSI, again being a sea level reading. With that standard the pressure at Denver is 12.1 PSI or a barometer of about 24.63. At this pressure water boils at about 202F instead of 212F.

The percentage of oxygen in the atmosphere does not change with altitude, so it is about 21% at 10 000 feet. What does change is the pressure. This declines with altitude. At sea level the air pressure is about 101 kPa (kilopascals). Oxygen accounts for 21% of this so the oxygen pressure is 19.6 kPa. This means that there are less oxygen molecules in the same volume of air at higher altitudes. At 10000 feet the oxygen pressure drops to 7.2 kPa, which is roughly one third of the pressure at sea level. For an online calculator of oxygen levels at different altitudes see: http://www.altitude.org/calculators/oxygencalculator/oxygencalculator.htm This site also lets you convert between kilopascals and mm Hg.

It is about 841 miles via I-25. A shorter route via US-160 will save 85 miles but adds an extra hour and a half to the driving time. The single advantage to that route is to visit the Four Corners area.

It is 537.37 miles according to MapQuest.
