Easily one of the prettiest parts of the country, though I've never been to Maine....but like the other reply said, let's keep it a bit of a Midwest secret.
Pikes Peak is a 14 thousand foot tall mountain in Colorado. It's one of the most iconic mountains of the US, and is sometimes referred to as Americas Mountain. However if you go north about 75 miles from pikes peak you are at Denver which usually makes simplified maps like this one, Pikes Peak is rarely noted on maps
Alaskan here. Image search for a US map. If the map even includes Alaska and Hawaii (the 49th and 50th states), they are usually not more than a smudge in the lower left corner of the page. Most US maps contain more details for regions that aren't even in the US than its largest and most northern, western, and eastern state. Though not self-evident in this map, there is also a still to this day consistent trend of exclusion when it comes to things that simply refer to "the US". So someone made a map that exaggerates the mediocrity of what we refer to as the "lower 48". For the artistic value, it's a very popular map up here.
