The ''Tuuwaqatsi'' or earth symbol is the main symbol of the Hopi people. Says Donald Healy in his book "Native American Flags":
{{QuoteCita|text=Centered on the white stripe is a black ring, divided (north-south and east-west) into four quarters by a black cross. Within each of the quarters is a black dot. Below this Tuuwaqatsi or earth symbol is a depiction of mountains in brown. Two stalks of corn, the main food of the Hopis, emerge from the corners of the mountains. Arcing over this entire symbol is the word "HOPI" in a black typeface.|sign=Donald T. Healy, Native American Flags, p. 94}}
