Who cares if Wasatch is too obscure for some rando in New York or Örnsköldsvik, that’s precisely why I think it’s kind of interesting. Its ties together local geography and is a nod to the native peoples as well.
It is kind of a nebulous nickname but I’d say it offers some flexibility in the branding potential. Obviously you have the tie in with the mountains but also the Shoshoni translation to “blue Herron” which can riff off the blue coloring already established and the species of Herron native to the area that can lend more to the identity package and mascot.
I really, really like it.
