Also they look like Western Canada..
You know...You’re right!
I like to think outside the norm on this stuff. Its how I deal with insomnia.
Imagine a planet tidally locked in a close orbit to a red dwarf which in turn orbits a much larger main sequence star. One side of the planet would always face the red dwarf while the side away from the star would have a long day/night cycle as the planet orbited the dwarf.
I recently threw a twist into it by making the orbit around the large star, long and elliptical which would force a migration toward the red dwarf side of the planet every 5 or 10 years.
