TheOsage Hills is a hilly area inOklahoma, commonly known asThe Osage. The name refers to the broad rolling hills and rollingtallgrass prairie andCross Timbers encompassingOsage County and surrounding areas, including portions of Mayes, Tulsa, Washington and Kay Counties. The Osage is the southern extension of theFlint Hills of Kansas.
The Osage contains some of the largest remaining remnants of the tallgrass prairie that covered much of theGreat Plains (seeTallgrass Prairie Preserve). Kansans generally refer to the northern portion of this same prairie system as the Flint Hills.
Historically, most of this area was the last reserve of theOsage Indians and its rugged environs hid outlaws and illicit activity well into the twentieth century. TheNellie Johnstone No. 1, a well drilled near present-dayBartlesville, struck oil on April 15, 1897, and became the first of thousands of commercial oil wells in Oklahoma. The Osage Indians had wisely held on to their mineral rights following the dissolution of the reservation system,[1] and the royalties from the oil underneath the hills made them one of the richest tribes in the nation.
Prominent attractions in the Osage Hills include the Osage Hills State Park,Tulsa Botanic Garden,[2] Tulsa'sGilcrease Museum (which has extensive gardens covering 23 acres (93,000 m2),Woolaroc andThe Nature Conservancy'sTallgrass Prairie Preserve which offers long vistas of tallgrass prairies and buffalo herds; andKaw Lake and theArkansas River in Kay Country which form the western boundary of the Osage.
Several enterprises or organizations in the area useOsage Hills to identify themselves with the area; including Osage Hills Public Schools in Bartlesville andOsage Hills State Park west of Bartlesville. Other areas within Oklahoma, Kansas, and Missouri also may use the name "Osage Hills" although may not actually be within the specific Osage Hills area.
