Upper Redwater Lake is a narrow freshwater lake in the municipality of Temagami of Northeastern Ontario, Canada, located southeast of the former Rabbit Creek ballast pit along Rabbit Creek Road that comes out at Highway 11.
 The settlement of Redwater is located on the southeastern shore of Upper Redwater Lake and the Ontario Northland Railway mainline runs along its entire western shore.
 Its northern end is crossed by the Ontario Northland Railway where the lake sways northeastwards.
 At the southern end of the lake is a strait that connects Upper Redwater Lake with Lower Redwater Lake.
The Indian Removal Act was signed by President Andrew Jackson on May 28, 1830.
 The law authorized the president to negotiate with southern Indian tribes for their removal to federal territory west of the Mississippi River in exchange for their lands.
 The act enjoyed strong support from the non-Indian peoples of the South, but there was a large amount of resistance from the Indian tribes.
 Cherokee tribes came together as an independent nation to stop this relocation, but they were unsuccessful.
The Treaty of Dancing Rabbit Creek was a treaty signed on September 27, 1830, and proclaimed on February 24, 1831, between the Choctaw American Indian tribe and the United States Government.
 This was the first removal treaty carried into effect under the Indian Removal Act.
 The treaty ceded about 11 million acres (45,000 km) of the Choctaw Nation in what is now Mississippi in exchange for about 15 million acres (61,000 km) in the Indian territory, now the state of Oklahoma.
 The principal Choctaw negotiators were Chief Greenwood LeFlore, Musholatubbee, and Nittucachee; the U.S. negotiators were Colonel John Coffee and Secretary of War John Eaton.
The history of Meridian, Mississippi begins in the early 19th century before European-American settlement.
 Originally settled by the Choctaw Indians, the land was bought by the United States according to the Treaty of Dancing Rabbit Creek in 1830.
 The city grew around the intersection of the Mobile and Ohio Railroad and the Southern Railway of Mississippi and developed a largely rail-based economy.
 Although much of the city was burned down in the Battle of Meridian during the American Civil War, the city was rebuilt and entered a "Golden Age."
 Between about 1890 and 1930, the city was the largest in Mississippi and a leading center for manufacturing in the Southern United States.
 After the decline of the railroading industry in the 1950s, the city's economy was devastated, resulting in a slow population decline.
 The population has continued to decline as the city has struggled to create a new, more modern economy based on newer industries.
 In the past 20 years or so, Meridian has attempted to revitalize the city's economy by attracting more business and industry to the city, most specifically the downtown area.
Rabbit Mountain is an eroded volcanic outcrop in the Wrangell Volcanic Field, Yukon Territory, Canada, located 30 km southwest of Koidern and 4 km northwest of Canyon Mountain.
 It is east of the Yukon-Alaska boundary and can be accessed by old mining roads that reach Rabbit Creek.
 Rabbit Mountain formed as a result of melting of the crust, due to subduction of the Pacific Plate beneath the North American Plate and last erupted during the Pliocene.
 Like most volcanoes in the Yukon, Rabbit Mountain is part of the Pacific Ring of Fire, that includes over 160 active volcanoes.
Rabbit Creek is a tributary to the Humboldt River located in Elko County, Nevada.
 The creek was originally named Seitz Creek after two brothers who settled near present day Pleasant Valley.
 The creek flows from early April to August.
 The creek is used to irrigate over 3,000 acres of harvest crop and 206 acres of diversified pasture.
 The earliest water rights on the creek have a priority of 1862.
 Major users of the creek include Ruby Dome Ranch, Sarman Ranch, Woodbury Ranch, and Boyd Reservoir.
Bonanza Creek is a watercourse in Yukon Territory, Canada.
 It runs for about 20 mi from King Solomon's Dome to the Klondike River.
 In the last years of the 19th century and the early 20th century, Bonanza Creek was the centre of the Klondike Gold Rush, which attracted tens of thousands of prospectors to the creek and the area surrounding it.
 Prior to 1896 the creek was known as Rabbit Creek.
 Its name was changed by miners in honour of the millions of dollars in gold found in and around the creek.
Greenwood LeFlore or Greenwood Le Fleur (June 3, 1800 – August 31, 1865) was elected Principal Chief of the Choctaw in 1830 before removal.
 Before that, the nation was governed by three district chiefs and a council of chiefs.
 A wealthy and regionally influential Choctaw of mixed-race, who belonged to the Choctaw elite due to his mother's rank, LeFlore had many connections in state and federal government.
 In 1830 LeFlore led other chiefs in signing the Treaty of Dancing Rabbit Creek, which ceded the remaining Choctaw lands in Mississippi to the US government and agreed to removal to Indian Territory.
 It also provided that Choctaw who chose to stay in Mississippi would have reserved lands, but the United States government failed to follow through on this provision.
The Dancing Rabbit Creek Treaty Site is a historic Choctaw Native American gathering place in rural Noxubee County, Mississippi.
 Located near a freshwater spring above the floodplain of Dancing Rabbit Creek in the southwestern part of the county, it was the site of a treaty negotiation between the Choctaw and the federal government in 1830, resulting in the Treaty of Dancing Rabbit Creek, in which the Choctaw agreed to surrender their ancestral lands for territory in what is now Oklahoma.
 It was the first treaty negotiated after passage of the Indian Removal Act, and served as a model for other treaties passed pursuant to that act.
 It also led to the Choctaw Trail of Tears.
 The site, now marked by a stone memorial and a small Choctaw cemetery, was designated a National Historic Landmark in 1996.
