Deepwater Horizon explosion and oil spill Skyscrapers Geologists and other Earth scientists agree in general that the present Gulf of Mexico basin originated in Late Triassic time as the result of rifting within Pangea the rifting was associated with zones of weakness within Pangea including sutures where the Laurentia South American and African plates collided to create it First there was a Late Triassic-Early Jurassic phase of rifting during which rift valleys formed and filled with continental red beds Second as rifting progressed through Early and Middle Jurassic time continental crust was stretched and thinned This thinning created a broad zone of transitional crust which displays modest and uneven thinning with block faulting and a broad zone of uniformly thinned transitional crust which is half the typical 40 kilometer thickness of normal continental crust it was at this time that rifting first created a connection to the Pacific Ocean across central Mexico and later eastward to the Atlantic Ocean This flooded the opening basin to create the Gulf of Mexico as an enclosed marginal sea While the Gulf of Mexico was a restricted basin the subsiding transitional crust was blanketed by the widespread deposition of Louann Salt and associated anhydrite evaporites During the Late Jurassic continued rifting widened the Gulf of Mexico and progressed to the point that sea-floor spreading and formation of oceanic crust occurred at this point sufficient circulation with the Atlantic Ocean was established that the deposition of Louann Salt ceased. Seafloor spreading stopped at the end of Jurassic time about 145-150 million years ago. Harris County ESD #10 Fire Eastex Fire Department 1% .10. ; .
Farmers and ranchers were especially hard hit as prices for cotton and livestock fell sharply Beginning in 1934 and lasting until 1939 the Dust Bowl an ecological disaster of severe wind and drought caused an exodus from Texas and the surrounding plains in which over 500,000 Americans were homeless hungry and jobless. Thousands left the region forever to seek economic opportunities in California For the majority of farmers who remained the New Deal's Agricultural Adjustment Act was a crash program started in 1933 that in two weeks signed up cotton growers even as agents and committeemen faced poor roads bureaucratic delays inadequate supplies balking mules and language barriers it brought recovery by the mid-1930s raising cotton prices by controls on how much farmers could plant. The Comanche agreed to a peace treaty in 1785 the Comanche were willing to fight the enemies of their new friends and soon attacked the Karankawa Over the next several years the Comanche killed many of the Karankawa in the area and drove the others into Mexico.
