The shield of Sinaloa consists of an oval-shaped pitaya divided into four sections which each represent a city of the State. The upper dexter section represents Culiacán, the upper sinister section represents El Fuerte, the lower dexter section represents El Rosario and the lower sinister section represents Mazatlán. The pitaya also includes its characteristic thorns; human footprints which symbolize the pilgrimage of the people of Aztlan on its way to Tenochtitlan; and the text Sinaloa 1831.
The eagle on top of it resembles the shield used when Sinaloa and Sonora were a Estado de Occidente between 1821 and 1831.
Sinaloa flag - The flag features a tomato in the middle, as depicted on the states' car licence plates. Green and yellow are colors associated with sinaloa. Flag proposed by daviddelgadohh (2017).
The four colours represent the four areas of the local economy, blue for fishing, green for agriculture, red for livestock and white for the food industry - as Sinaloa is said to be the breadbasket of Mexico. The colours appear in a mappy fashion with the Gulf of California to the southwest, the white sandy beaches and the Humaya river cutting down from the Sierra Madre Occidental range in green and the city life in Culiancan Rosales as the hot Mexican red. The curves also echo the rolling landscapes and the forward thinking dynamism of a new generation. By Rotten Ali. 2017.
