You Will Ever Own. The word burro is derived from the Spanish word borrico meaning donkey.
Burro refers to a small donkey, often used as a pack animal.
The presence of burros as free-roaming animals in the hills and mountains of the lower Colorado River Valley came after the discovery of gold at Gila City in 1858. With the discovery of gold, prospectors poured into the area from California and Sonora, Mexico, and brought with them little sturdy pack burros. In the barren, nearly waterless hills, the burro adapted well and became indispensable to prospectors. Burros were used as pack animals for the prospectors, worked in the mines hauling ore, and carried supplies, water, and even machinery into desolate mining camps. The lone prospector and his trusty pack burro became a legendary symbol of the Old West.
