Land Rush of 1889. The Oklahoma Land Rush of 1889 was the first land rush into the Unassigned Lands. The area that was opened to settlement included all or part of the present-day Canadian, Cleveland, Kingfisher, Logan, Oklahoma, and Payne counties of the US state of Oklahoma.
By the early 1840s it was becoming difficult for miners to make a living washing the placer deposits, and hard-rock gold veins were becoming harder to mine. The heyday of the gold rush was over. In 1849 word of the great California gold strikes reached the miners of Georgia, and they began preparing to go west.
