Galiano had received letters of suggestion and order from both Malaspina and Viceroy Revillagigedo. Malaspina urged a stop at San Francisco on the return, in order to map and assess the Spanish colony there, which Malaspina's expedition had been unable to do. The viceroy, while not directly contradicting Malaspina, informed Galiano of the "almost continuous fog" at San Francisco and the lack of provisions compared to Monterey. Careful not to give contrary orders, the viceroy strongly suggested that Monterey would be a better place to stop than San Francisco. As it turned out, Galiano stopped at Monterey and not San Francisco, due to inclement weather. Both Malaspina and the viceroy also urged Galiano to investigate the "Entrada de Ezeta" (the mouth of the Columbia River), which the Spanish expedition of Bruno de Heceta (also spelled Ezeta) had sighted in 1775, but had been unable to enter or even determine whether it was a river or a strait. At Nootka Sound Galiano learned from Juan Francisco de la Bodega y Quadra that Robert Gray had already entered the river. Quadra had given Galiano a sketch map of the river's mouth based on Gray's information. Galiano sighted the Columbia River on 8 September 1792. He did not enter the river, claiming that his ships were inappropriate for the task. However he did fix the location and determine that it was a river and not a strait.
