Question: When did the state where rhodochrosite is found become part of the United States?

full_context: Document 1: Ohio: On February 19, 1803, U.S. President Thomas Jefferson signed an act of Congress that approved Ohio's boundaries and constitution. However, Congress had never passed a resolution formally admitting Ohio as the 17th state. The current custom of Congress declaring an official date of statehood did not begin until 1812, with Louisiana's admission as the 18th state. 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. On August 7, 1953 (the year of Ohio's 150th anniversary), President Eisenhower signed a congressional joint resolution that officially declared March 1, 1803, the date of Ohio's admittance into the Union.
Document 2: 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 3: Amethyst: It is also found and mined in South Korea. The largest opencast amethyst vein in the world is in Maissau, Lower Austria. Much fine amethyst comes from Russia, especially from near Mursinka in the Ekaterinburg district, where it occurs in drusy cavities in granitic rocks. Many localities in south India yield amethyst. One of the largest global amethyst producers is Zambia in southern Africa with an annual production of about 1000 tons.
Document 4: Rhodochrosite: Rhodochrosite is Argentina's ``national gemstone ''. Colorado officially named rhodochrosite as its state mineral in 2002. Large specimens have been found in the Sweet Home Mine near Alma, Colorado.
Document 5: Southern California: Subsequently, Californios (dissatisfied with inequitable taxes and land laws) and pro-slavery southerners in the lightly populated "Cow Counties" of southern California attempted three times in the 1850s to achieve a separate statehood or territorial status separate from Northern California. The last attempt, the Pico Act of 1859, was passed by the California State Legislature and signed by the State governor John B. Weller. It was approved overwhelmingly by nearly 75% of voters in the proposed Territory of Colorado. This territory was to include all the counties up to the then much larger Tulare County (that included what is now Kings, most of Kern, and part of Inyo counties) and San Luis Obispo County. The proposal was sent to Washington, D.C. with a strong advocate in Senator Milton Latham. However, the secession crisis following the election of Abraham Lincoln in 1860 led to the proposal never coming to a vote.
Document 6: Turquoise: The Southwest United States is a significant source of turquoise; Arizona, California (San Bernardino, Imperial, Inyo counties), Colorado (Conejos, El Paso, Lake, Saguache counties), New Mexico (Eddy, Grant, Otero, Santa Fe counties) and Nevada (Clark, Elko, Esmeralda County, Eureka, Lander, Mineral County and Nye counties) are (or were) especially rich. The deposits of California and New Mexico were mined by pre-Columbian Native Americans using stone tools, some local and some from as far away as central Mexico. Cerrillos, New Mexico is thought to be the location of the oldest mines; prior to the 1920s, the state was the country's largest producer; it is more or less exhausted today. Only one mine in California, located at Apache Canyon, operates at a commercial capacity today.
Document 7: Utah Territory: The Territory of Utah was an organized incorporated territory of the United States that existed from September 9, 1850, until January 4, 1896, when the final extent of the territory was admitted to the Union as the State of Utah, the 45th state.
Document 8: 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 11: History of Colorado: The United States Congress passed an enabling act on March 3, 1875, specifying the requirements for the Territory of Colorado to become a state.

Grant signed a proclamation admitting the state of Colorado to the Union as the 38th state and earning it the moniker ``Centennial State ''.

Document 13: 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.
