According to "Encyclopedia of Oklahoma History and Culture", the fort was about west of the present city of Sand Springs, Oklahoma. Author James Gardner visited the site in the early 1930s. His article describing the visit includes an old map showing the fort located on the north bank of the Arkansas River near Sand Creek, just south of the line separating Tulsa County and Osage County. After ground was cleared and a blockhouse built, Fort Arbuckle was abandoned November 11, 1834. The remnants of stockade and some chimneys could still be seen nearly a hundred years later. The site was submerged when Keystone Lake was built. Main article Battle of Chusto-Talasah  At the outbreak of the Civil War in 1861, many Creeks and Seminoles in Indian Territory, led by Opothleyahola, retained their allegiance to the U. S. Government. In November, 1861, Confederate Col. Douglas H. Cooper led a Confederate force against the Union supporters with the purpose of either compelling their submission or driving them out of the country. The first clash, known as the Battle of Round Mountain, occurred November 19, 1861. Although the Unionists successfully withstood the attack and mounted a counterattack, the Confederates claimed a strategic victory because the Unionists were forced to withdraw. The next battle occurred December 9, 1861. Cooper's force attacked the Unionists at Chusto-Talasah (Caving Banks) on the Horseshoe Bend of Bird Creek in what is now Tulsa County. The Confederates drove the Unionists across Bird Creek, but could not pursue, because they were short of ammunition. Still, the Confederates could claim victory. The Atlantic and Pacific Railroad had extended its main line in Indian Territory from Vinita to Tulsa in 1883, where it stopped on the east side of the Arkansas River. The company, which later merged into the St. Louis and San Francisco Railway (familiarly known as the Frisco), then built a steel bridge across the river to extend the line to Red Fork. This bridge allowed cattlemen to load their animals onto the railroad west of the Arkansas instead of fording the river, as had been the practice previously. It also provided a safer and more convenient way to bring workers from Tulsa to the oil field after the 1901 discovery of oil in Red Fork. A wildcat well named Sue Bland No. 1 hit paydirt at 540 feet on June 25, 1901 as a gusher. The well was on the property of Sue A. Bland (née Davis), located near the community of Red Fork. Mrs. Bland was a Creek citizen and wife of Dr. John C. W. Bland, the first practicing physician in Tulsa.
