Colorado Is Not a Rectangle–It Has 697 Sides

>> Congress defined the borders of Colorado as a geospherical rectangle, stretching from 37°N to 41°N latitude, and from 25°W to 32°W longitude.

I was confused by these longitudes (which a quick check puts the state somewhere over the Atlantic), but these are using the Washington Meridian. The correct longitude boundaries in usual coordinates are 102°03'W and 109°03'W.

Brit here, I always found how the state lines and even roads are organised in the US intriguing. Here it is a random set of roads and city boundaries but American ones seem to have been designed from scratch.
