Flag for the Western most point of the United States at 124 Degrees West by 48 Degrees North: Cape Alava, Washington State

The most western point of the United 48 States of the USA is in Washington State.  This is non-political truly scientific flag that has the colours ordered to numbers.  The numbers themselves represent latitude and longitude.  In this case red is 1, since it is the first colour in the rainbow.  Orange is 2, as it is the second colour of the rainbow, while green is 4, you guessed it, as it is the 4th colour of the official rainbow.  Thus 124 represents the longitude.  The white pentagon represents the Western Hemisphere, otherwise it'd be yellow for the Eastern Hemisphere.

The stars represents lines of latitude. In this case it is 48.  As the dominant star is pointing upwards, it indicates the Northern Hemisphere.
