How does significant altitude, like in Denver, affect the boiling point of water?

Answer

The boiling point drops.

At higher altitudes, atmospheric pressure is lower, which consequently lowers the temperature required for the water's vapor pressure to equal the surrounding pressure, resulting in a lower boiling point, around $203^ ext{F}$ ($95^ ext{C}$) in Denver.
