Flag for the Challenger Deep the Deepest part of the Oceans

Currently the deepest part of the Ocean belongs to the United States of America - the sea bottom leagues below Bikini Bottom: Challenger Deep.  It is with Guam and the Mariana Islands that the USA lays claim to an ultimate title of geographic titles.  With a depth of ~10,900 meters or ~35,900 feet, the USA can limbo lower and longer than any nation on Earth, thanks to Guam and the Mariana Islands.  Challenger Deep is more than 10 Kilometers below sea level and 20,000 leagues lower than the Dead Sea and a greater distance- than to the top of Mt. Everest. 

This flag is a geographic flag that indicates the latitude and longitude of this special spot on planet Earth at 142 Degrees East by 11 Degrees North.  The yellow pentagon in the center indicates that this place is in the Eastern Hemisphere.  The tribar of red, green, and orange indicates the number 142 which is the longitude of this area.  The two red five pointed stars indicates the number 11. 

The key below explains who these type of flags are read.  The central stars are coded to the latitude while the tribars is coded to the longitude.  The colour to number code is based upon the order of the rainbow.  Since red is the first colour it represents 1, orange is the second colour that represents 2, green is the fourth colour which represents 4.
