The Rio Grande Valley is not a valley, but a floodplain containing many oxbow lakes or resacas formed from pinched-off meanders in earlier courses of the Rio Grande. Early 20th-century land developers, attempting to capitalize on unclaimed land, utilized the name "Magic Valley" to attract settlers and appeal to investors. The Rio Grande Valley is also called El Valle, the Spanish translation of "the valley", by those who live there. The residents of the Rio Grande Valley occasionally refer to the area as "El Magico Valle del Rio Grande" ("The Magical Valley of the Rio Grande"), and also simply by the initials R.G.V.
