Death Valley tourists get egg warning The park, which lies up to 86 metres below sea level, is the lowest and driest part of North America, and holds the record for the highest recorded air temperature on Earth. A spokesman for the park explained on its Facebook page: "An employee's posting of frying an egg in a pan in Death Valley was intended to demonstrate how hot it can get here, with the recommendation that if you do this, use a pan or tin foil and properly dispose of the contents However, the Death Valley NP maintenance crew has been busy cleaning up eggs cracked directly on the sidewalk, including egg cartons and shells strewn across the parking lot. It added: "This is your national park, please put trash in the garbage or recycle bins provided and don't crack eggs on the sidewalks." Death Valley, located across California and Nevada, will tomorrow celebrate the 100th anniversary of the day it claimed the world heat record - 57C. A temperature of 57.8°C was recording in the Libyan town of Al-Aziziyah, 40km south of Tripoli, on September 13, 1922. However this record was later dismissed as unreliable. The US has been in the grip of a massive heat wave in recent weeks, with temperatures at the park pushing 50C.
