In the period between 1866 and 1899, cattle ranches in Texas strove to meet the demands for food in eastern cities and railroads in Kansas promised to deliver in a timely manner. Cattle trails and cattle ranches developed as cowboys either drove their product north or settled illegally in Indian Territory. In 1881, four of five major cattle trails on the western frontier traveled through Indian Territory.

Borders

Oklahoma's border with Kansas was defined as the 37th Parallel in the 1854 Kansas-Nebraska Act. This was disputed with the Cherokee and Osage Nations which claimed their border extended North of this line and could not be part of the Kansas Territory. This was resolved in the 1870 with the
Drum Creek Treaty The Drum Creek Treaty came about from the controversy over the Sturges Treaty of 1868. The Sturges Osage Treaty was a treaty negotiated between the United States and the Osage Nation in 1868. The treaty was submitted to both the United States Ho ...
that reestablished Kansas's Southern Border as the 37th Parallel. This also applied to the then No-Man's Land that became the Oklahoma Panhandle. The Oklahoma-Texas border consists of the Red River in the South and the 100th Meridian West as Western border between Oklahoma and the Texas Panhandle. These were first established in the 1819 Adams–Onís Treaty between the United States and Spain. The Oklahoma panhandle was originally part of the Panhandle of the Republic of Texas, but when Texas joined the Union as a slave state, it could not retain any lands north of 36 degrees 30 minutes, as specified in the
Missouri Compromise The Missouri Compromise was a federal legislation of the United States that balanced desires of northern states to prevent expansion of slavery in the country with those of southern states to expand it. It admitted Missouri as a slave state and ...
. The Panhandle existed as a no-man's land until 1907 when Oklahoma acquired the territory upon gaining statehood. Oklahoma's Eastern border is divided between Missouri and Arkansas. The Missouri-Oklahoma border is defined as the Meridian passing through the Kawsmouth, where the Kansas River meets the Missouri River. This is the same Meridian as the Kansas-Missouri border. The Oklahoma-Arkansas border was originally defined by two lines: the borders between Arkansas and the Cherokee and Choctaw Reservations. This formed two diagonal lines meeting at the western edge of Fort Smith Arkansas, with one line running northeast from the Red River and the other running southeast from the Oklahoma-Arkansas-Missouri border. The Choctaw-Arkansas border was established in the 1820 Treaty of Doak's Sand, and later refined in the 1830
Treaty of Dancing Rabbit Creek The Treaty of Dancing Rabbit Creek was a treaty which was signed on September 27, 1830, and proclaimed on February 24, 1831, between the Choctaw American Indian tribe and the United States Government. This treaty was the first removal treaty wh ...
. These treaties left a 57-acre exclave of the Choctaw reservation bounded by Arkansas, the Arkansas River and the Poteau River. This became the site of a smuggling camp called "Coke Hill", noted mostly for its importance in cocaine smuggling. After Petitioning congress to hand over jurisdiction, the 57 acres was given to Arkansas in 1905. The 1985 US Supreme Court Case Oklahoma v. Arkansas decided the land would remain Arkansas, even though the Choctaw had not been notified or asked about the territory being handed over. Therefore, the Poteau River serves as the Oklahoma-Arkansas boundary for approximately 1 mile, reducing the Choctaw Reservation and later Oklahoma by 57 acres as established in the treaties of the early 1800s.

Among the most geographically diverse states, Oklahoma is one of four to harbor more than 10 distinct ecological regions, with 11 in its borders—more per square mile than in any other state. Its western and eastern halves, however, are marked by extreme differences in geographical diversity: Eastern Oklahoma touches eight ecological regions and its western half contains three. Although having fewer ecological regions Western Oklahoma contains many rare, relic species. Oklahoma has four primary mountain ranges: the

Because of Oklahoma's position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely over relatively short distances, and they can change drastically in a short time. On November 11, 1911, the temperature at Oklahoma City reached (the record high for that date), then a cold front of unprecedented intensity slammed across the state, causing the temperature to reach (the record low for that date) by midnight. This type of phenomenon is also responsible for many of the tornadoes in the area, such as the 1912 Oklahoma tornado outbreak when a warm front traveled along a stalled cold front, resulting in an average of about one tornado per hour.

Average monthly precipitation increases dramatically in the spring to a peak in May, the wettest month over most of the state, with its frequent and not uncommonly severe thunderstorm activity. Early June can still be wet, but most years see a marked decrease in rainfall during June and early July. Mid-summer (July and August) represents a secondary dry season over much of Oklahoma, with long stretches of hot weather with only sporadic thunderstorm activity not uncommon many years. Severe drought is common in the hottest summers, such as those of 1934, 1954, 1980 and 2011, all of which featured weeks on end of virtual rainlessness and highs well over .
