Nav Question
I was recently posed the following brain teaser by a mate at a pub quiz:
"What are the most Northerly, Easterly, Westerly and Southerly states in the US?"
The most Northern and Southern were, obviously, Alaska and Hawaii respectively. But, he went on to say that the most Westerly and Easterly State was Alaska as well.
His reasoning was based around the Aleutian Islands near the Russian coast. This island chain apparently stretches round so far that the Westernmost tip is actually further West than Hawaii. So far, so good.
However, he went on to say, the Islands cross the International Date Line and so are also further East than the East Coast. I think his reasoning here is wrong and probably stems from looking at a world wall map, which might give the impression that any point on the right side of the map are further East than points further to the left of the map (i.e the continental US).
As I understand it, the International Date Line is a time zone device only and would have no effect on your frame of reference for navigation. In other words, if I travel a short distance in a Westerly direction across the IDL then I am a short distance West of my starting position, rather than being a long way East of it!
Try as I might, I could not explain this to him. Does anyone have any simple way of clarifying my position which I can present on our next meeting?
Thanks
