Francisco Vasquez de Coronado on the Texas Plains. On April 22, 1540, Francisco Vasquez De Coronado (1510-54) set out from Culiacan (in present Sinaloa, Mexico) with an expedition of 1500 men to search for seven golden cities reported far to the north. Coronado entered the present United States in Arizona and proceeded northeast to the Rio Grande pueblos in New Mexico where he spent the winter of 1540-41. On April 23, 1541, Coronado left the Rio Grande, traveling eastward to seek the Golden City of Quivira. A native guide called "El Turco" led the Conquistadores aimlessly across the arid plains in an attempt to get them lost. On May 29, 1541, with supplies depleted, Coronado entered Palo Duro Canyon, where wild fruit and water abounded. While in the canyon, Coronado discovered the guide's betrayal. On June 2, Coronado selected 30 men and started northward in quest of Quivira. The rest of the expedition, under command of Tristan De Arellano, remained in the canyon for 2 weeks before returning to the Rio Grande. According to legend, Fray Juan De Padilla conducted a feast of Thanksgiving for the group while in Palo Duro Canyon. In 1542, after failing to find the Seven Cities of Gold, Coronado returned to Mexico a broken man. (1973) #2048
