Notes on: ‘The North Coast of America’

The world’s longest international boundary of 5,520 miles exists between the world’s 2nd largest (Canada) and 3rd largest (USA) countries; of this total 63%, or 3,465 miles are coastal boundary miles, AKA, The North Coast.

the U.S.A’s 3,465 North Coast’s/coastal miles are longer than:

The East Coast’s 2,170 coastal miles
The West Coast’s 1,300 coastal miles
The Gulf Coast‘s 1,630 coastal miles

The North Coast is “almost” equal to the sum of the East and West coasts. Four of the 5 Great Lakes are part of the coastal boundary. ( Lake Michigan is entirely enclosed with in the U.S.). Combined, the five Great Lakes represent 20% of the world’s freshwater supply. One memory hook for the names of the Great Lakes is ’S-H-O-M-E’:

’S’ Superior, by surface area, is the world’s 2nd largest & has 1,250
boundary miles
‘H’ Huron is 4th largest lake in the world, but only 206 boundary miles
‘O’ Ontario, smallest, yet still world’s 13th largest, & 193 boundary miles
‘M’ Michigan is 5th largest, no boundary miles but longest shoreline
of any contiguous state, with 3.288 shoreline miles
‘E’ Erie is 11th largest in the world & has 241 boundary miles

On the pathway are 5 effected rivers with coastal boundary frontage.

The St Mary’s River with 120 miles
The St Clair River 40 miles
The Detroit River 70 miles
The Niagra River 70 miles
The Saint Lawrence River 144 miles

The 3,465 boundary mile portion of the 5,520 mile international boundary touches on 5 American states, whose combined population is approx. 18% of America’s total population: Michigan, Minnesota, New York, Ohio and Pennsylvania.
