Webcam Cache. In order to visit this cache you need a 4-wheel drive vechicle, over 16 years of age (a rule set up by the organizations that run the telescopes) and of good health (only 40% oxygen level). Cache is at 13,712 ft above sea-level.
The webcam takes a picture every five minutes and can be viewed at

When you stand in front of the webcam, call someone who can goto the site and save your picture, then later upload it to Geocaching.com and me.
