Snowflake is a town in Navajo County, Arizona, United States. It was founded in 1878 by Erastus Snow and William Jordan Flake, Mormon pioneers and colonizers. It has frequently been noted on lists of unusual place names. According to 2012 Census Bureau estimates, the population of the town is 5,564.
I would guess that the "esteemed" Senator Jeff Flake is a descendant of Mr. Flake.
