The mountains meet the plains in Sweet Grass County. Bigger than the State of Rhode Island, the county is 1,846 square miles - 449 of which are public lands. The eastern and northern parts of the county are devoted to agriculture, mostly the raising of cattle and sheep. Some farming of crops that require little moisture is also done.
The county reaches into the Crazy Mountains on the north and west. There are several theories of how the mountains got their name. All date back to indian lore. Although in close proximity to the Rockies, the Crazies are not a part of that chain. To the south lies the Absaroka Range. The Gallatin National Forest and Absaroka Beartooth Wilderness act as a boundary between the county and Yellowstone National Park.
Two rivers trisect the county. The Yellowstone River runs east and west. The Boulder River flows from its source in the Absaroka Beartooth Wilderness and joins the Yellowstone just east of Big Timber.
Seven creeks lend their names to areas of Sweet Grass County. Big Timber Creek, Otter Creek and Sweet Grass Creek come out of the Crazies and flow into the Yellowstone from the north. Upper Deer Creek, Lower Deer Creek, Bridger Creek and Work Creek start in the Absarokas and flow into the Yellowstone from the south.
Sweet Grass County has a population of about 3,500. Sixteen hundred live in Big Timber.
