Quadripoint
The Four Corners Monument is the only point in the United States where four states meet: Colorado, Utah, New Mexico, and Arizona meet at right angles. The United States first acquired the area now called Four Corners from Mexico after the Mexican–American War in 1848. In 1863 Congress created Arizona Territory from the western part of New Mexico Territory. The boundary was defined as a line running due south from the southwest corner of Colorado Territory, which had been created in 1861. By defining one boundary as starting at the corner of another Congress ensured the eventual creation of four states meeting at a point, regardless of the inevitable errors of boundary surveying.

Four Counties Ring
The Four Counties Ring, which offers a variety of scenery and cruising for a narrowboat holiday, takes in the counties of Cheshire, Shropshire, Staffordshire and West Midlands.
Highlights include the Industrial Canal Heritage of the Stoke-on-Trent potteries region, the wealthy pasturelands of Cheshire, to the stunning remote sandstone cuttings of Shropsire.
This route, which is 110 miles long and includes 94 locks, is commonly used by holiday boaters. While energetic crews may be able to complete the ring in just a week, those who do not want to be cruising all day for the entire week will typically take two weeks.
