This is regarded as the easternmost point of the USA (at least that you can travel to). Interestingly the westernmost point of the USA (that you can travel to) is also called Point Udall. That is in Guam. These were named after two brothers.

Now, technically, these are NOT the easternmost or westernmost points of the USA. That would be a part of uninhabited Alaska which is actually on the other side of the 180 degree longitude.

But I was not going to pick up a fight with the local inhabitants!!
