Question: What's the only major mountain range between the Appalachian Mountains and the mountains higher than those in temperate parts of the state where Chickamauga Lake is located?

the topography of the state is roughly defined by the continental divide, which splits much of the state into distinct eastern and western regions. most of montana's 100 or more named mountain ranges are concentrated in the western half of the state, most of which is geologically and geographically part of the northern rocky mountains. the absaroka and beartooth ranges in the south-central part of the state are technically part of the central rocky mountains. the rocky mountain front is a significant feature in the north-central portion of the state, and there are a number of isolated island ranges that interrupt the prairie landscape common in the central and eastern parts of the state. about 60 percent of the state is prairie, part of the northern great plains. <SEP> The Appalachian Mountains (French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east - west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east - west. <SEP> The lake stretches from Watts Bar Dam at mile 529.9 (853 km) to Chickamauga Dam at mile 471.0 (758 km) making the lake 58.9 miles (94.8 km) long. It borders Rhea County, Meigs County, and Hamilton County with 810 miles (1,303 km) of shoreline and two bridges crossing it at State Highway 60 and Highway 30. The lake is commonly used for recreational and outdoor activities, especially at the southern end, due to the high population density surrounding it. It was named after the Chickamauga (tribe) of Cherokees who used to live in the area. Chickamauga Lake is a reservoir in the United States along the Tennessee River created when the Chickamauga Dam, as part of the Tennessee Valley Authority, was completed in 1940. <SEP> Interior Highlands, the only major mountainous region between the Rocky Mountains and the Appalachian Mountains. The Great Plains lie west of the Mississippi River and east of the Rocky Mountains. A large portion of the country's agricultural products are grown in the Great Plains. Before their general conversion to farmland, the Great Plains were noted for their extensive grasslands, from tallgrass prairie in the eastern plains to shortgrass steppe in the western High Plains. Elevation rises gradually from less than a few hundred feet near the Mississippi River to more than a mile high in the High Plains. The generally low relief of the plains is broken in several places, most notably in the Ozark and Ouachita Mountains, which form the U.S. <SEP> the blue mountains is a mountainous region and a mountain range located in new south wales, australia. the region borders on sydney's metropolitan area, its foothills starting about 50 kilometres (31 mi) west of the state capital. the public's understanding of the extent of the blue mountains is varied, as it forms only part of an extensive mountainous area associated with the great dividing range. officially the blue mountains region is bounded by the nepean and hawkesbury rivers in the east, the coxs river and lake burragorang to the west and south, and the wolgan and colo rivers to the north. geologically, it is situated in the central parts of the sydney basin. <SEP> The Gulf of Mexico is the dominant factor in the climate of Tennessee, with winds from the south being responsible for most of the state's annual precipitation. Generally, the state has hot summers and mild to cool winters with generous precipitation throughout the year, with highest average monthly precipitation generally in the winter and spring months, between December and April. The driest months, on average, are August to October. Most of the state has a humid subtropical climate, with the exception of some of the higher elevations in the Appalachians, which are classified as having a mountain temperate climate or a humid continental climate due to cooler temperatures. On average the state receives 50 inches (130 cm) of precipitation annually. Snowfall ranges from 5 inches (13 cm) in West Tennessee to over 16 inches (41 cm) in the higher mountains in East Tennessee.
