I contacted Nalgene about the temps that their bottles can handle. The bottles that I use are the Polycarbonite/Lexan PC and have a PP lid with a LDPE Strap. These are the standard translucent ones that you get from your outdoors store.

Here is some info on the boiling point of water.
The reason foods have high altitude instructions is because the boiling point of water changes with altitude. As you go higher, the boiling temperature decreases.
At sea level, the boiling point of water is 212 degrees F (100 degrees C). As a general rule, the temperature decreases by 1 degree F for every 540 feet of altitude (0.56 degrees C for every 165 meters). On top of Pike's Peak, at 14,000 feet, the boiling point of water is 187 degrees F (86 degrees C). So pasta or potatoes cooked at sea level are seeing 25 degrees more heat than pasta or potatoes cooked on Pike's Peak. The lower heat means a longer cooking time is needed.
