Question: When did the U.S. state containing Hinsdale county become part of the United States?

full_context: Document 1: Colorado Territory: Colorado Territory was officially organized by Act of Congress on February 28, 1861, out of lands previously part of the Kansas, Nebraska, Utah, and New Mexico territories. Technically the territory was open to slavery under the Dred Scott Decision of 1857, but the question was rendered moot by the impending American Civil War and the majority pro-Union sentiment in the territory. The name "Colorado" was chosen for the territory. It had been previously suggested in 1850 by Senator Henry S. Foote as a name for a state to have been created out of present-day California south of 35° 45'. To the dismay of Denverites, the town of Colorado City was designated the first territorial capital, quickly succeeded by Golden. Denver eventually became the temporary territorial capital, but was not designated the permanent capital until 1881, five years after Colorado became a state.

Document 3: Colorado Territory: The movement to create a territory within the present boundaries of Colorado followed nearly immediately. Citizens of Denver and Golden pushed for territorial status of the newly settled region within a year of the founding of the towns. The movement was promoted by William Byers, publisher of the Rocky Mountain News, and by Larimer, who aspired to be the first territorial governor. In 1859, settlers established the Territory of Jefferson, and held elections, but the United States Congress did not recognize the territory, and it never gained legal status.

Document 7: Montana: Under Territorial Governor Thomas Meagher, Montanans held a constitutional convention in 1866 in a failed bid for statehood. A second constitutional convention was held in Helena in 1884 that produced a constitution ratified 3:1 by Montana citizens in November 1884. For political reasons, Congress did not approve Montana statehood until 1889. Congress approved Montana statehood in February 1889 and President Grover Cleveland signed an omnibus bill granting statehood to Montana, North Dakota, South Dakota and Washington once the appropriate state constitutions were crafted. In July 1889, Montanans convened their third constitutional convention and produced a constitution acceptable by the people and the federal government. On November 8, 1889 President Benjamin Harrison proclaimed Montana the forty-first state in the union. The first state governor was Joseph K. Toole. In the 1880s, Helena (the current state capital) had more millionaires per capita than any other United States city.

Although no formal resolution of admission was required, when the oversight was discovered in 1953, Ohio congressman George H. Bender introduced a bill in Congress to admit Ohio to the Union retroactive to March 1, 1803, the date on which the Ohio General Assembly first convened. At a special session at the old state capital in Chillicothe, the Ohio state legislature approved a new petition for statehood that was delivered to Washington, D.C. on horseback.
