| Here is the treacherous twosome, Marshall and Gary, still
bundled up against the cold. Though we didn't look at the
thermometer, it actually got perceptibly colder as we climbed.
Standard physics says that the temps should drop 3 degrees per 1,000 ft of
altitude gained. But that temperature drop due to increased altitude
is ordinarily counterbalanced by heat from the rising sun accumulated
over the hours it took to make the climb. Near the top, we even had
to break out the gloves. My guess (your mileage may vary) is that
the atmosphere is so clear, that few warming light rays are scattered back
into the shadows where we were hiking.
This photo was taken at about 13,000 ft, near Trail Crest, looking back at Guitar Lake. From here, Guitar Lake and environs almost looks smooth and flat. However, one should review day 4's pictures to see what it is really like. Quite a difference. |
