Geography
Hidalgo County comprises 1,596 square miles (4,130 km2) of the Rio Grande delta. The northern part of the county has sandy and light loamy soils over deep reddish or mottled, clayey subsoils. In some areas limestone lies within forty inches of the surface. The southern part of the county has moderately deep to deep loamy surfaces over clayey subsoils. Along the Rio Grande brown to red clays occur. Hidalgo County is in the South Texas Plains vegetation area, which features grasses, mesquite, live oaks, and chaparral. Native plants, reduced in recent years by extensive farming, include chapote, guayacan, ebony, huisache, brasil, and yucca.
In 1982, 91 percent of the land was in farms and ranches, with 52 percent of the farmland under cultivation and 85 percent irrigated; 51 to 60 percent of the county was considered prime farmland. The primary crops were sorghum, cotton, corn, and vegetables; Hidalgo County led Texas counties in the production of cabbage, onions, cantaloupes, carrots, and watermelons. The primary fruits and nuts grown in the county were grapefruit, oranges, and pecans. Cattle, milk cows, and hogs were the primary livestock products. Natural resources included caliche, sand, gravel, oil, and gas. Oil and gas production in 1982 totaled 98,487,211,000 cubic feet (2.7888472×109 m3) of gas-well gas, 139,995 barrels of crude oil, 1,101,666 barrels of condensate, and 15,784,000 cubic feet (447,000 m3) of casinghead gas. The climate is subtropical and subhumid. Temperatures range from an average low of 47 °F/8 °C in January to an average high to 96 °F/36 °C in July; the average annual temperature is 73 °F/23 °C. Rainfall averages 23 in (580 mm) a year, and the growing season lasts for 320 days of the year.

Famous quotes containing the word geography:
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
—Derek Wall (b. 1965)
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
