The Gadsden Purchase (Spanish: Venta de La Mesilla "La Mesilla sale") is a 29,640-square-mile (76,800 km2) region of present-day southern Arizona and southwestern New Mexico that the United States acquired from Mexico by the Treaty of Mesilla, which took effect on June 8, 1854. The purchase included lands south of the Gila River and west of the Rio Grande where the U.S. wanted to build a transcontinental railroad along a deep southern route, which the Southern Pacific Railroad later completed in 1881–1883. The purchase also aimed to resolve other border issues. The first draft was signed on December 30, 1853, by James Gadsden, U.S. minister to Mexico, and by Antonio López de Santa Anna, president of Mexico. The U.S. Senate voted in favor of ratifying it with amendments on April 25, 1854, and then sent it to President Franklin Pierce. Mexico's government and its General Congress or Congress of the Union took final approval action on June 8, 1854, when the treaty took effect. The purchase was the last substantial territorial acquisition in the contiguous United States, and defined the Mexico–United States border. The Arizona cities of Tucson, Yuma and Tombstone are on territory acquired by the U.S. in the Gadsden Purchase. The financially strapped government of Santa Anna agreed to the sale, which netted Mexico $10 million (equivalent to $260 million in 2022). After the devastating loss of Mexican territory to the U.S. in the Mexican–American War (1846–48) and the continued unauthorized military expeditions in the zone led by New Mexico territorial governor and noted filibuster William Carr Lane, some historians argue that Santa Anna may have calculated it was better to yield territory by treaty and receive payment rather than have the territory simply seized by the United States.

The Tucson Gem, Mineral & Fossil Showcase are gem and mineral shows that take place annually in late January and February at multiple locations across the city of Tucson, Arizona. Most of the shows are open to the public, except for certain trade shows which require registration with a business license. The key event of the Gem, Mineral & Fossil Showcase is the Tucson Gem & Mineral Show produced by the Tucson Gem and Mineral Society. This show has been held annually since 1955 and now occupies 181,000 square feet (16,800 m2) of the Tucson Convention Center. Many museums and universities, including the Smithsonian Institution and the Sorbonne, have displayed at the Tucson Gem and Mineral Show. The first Tucson Gem and Mineral Show was held in an elementary school in 1955 and shortly thereafter moved to a Quonset hut at the Tucson Fair Grounds. In 1973, it moved into the Tucson Community Center, first occupying the North Exhibit Hall, then expanding into the Arena and upper Arena concourse. After the completion of the new facility in 1990, which is now called the Tucson Convention Center, the Tucson Gem and Mineral Show now occupies the Arena, Exhibition Halls A-B-C, Galleria and Ballrooms. Katherine Rambo estimates that between 1996 and 2010 there was an average of about thirteen hundred total dealers from forty-nine states and thirty-two countries in attendance, annually. The 2021 show was canceled due to the COVID-19 pandemic.The Tucson Gem, Mineral & Fossil Showcase is one of the single highest revenue-producing events for the Tucson economy. The estimated economic impact in 2019 was $131.4 million,according to Jane Roxbury, director of gem show services for Visit Tucson.The 2021 showcase was pushed back from the typical dates to April due to the COVID-19 pandemic. While some of the shows were present, the main show at the Tucson Convention Center and some of the other shows were cancelled.

Colossal Cave is a large cave system in southeastern Arizona, United States, near the community of Vail, about 22 miles (35 km) southeast of Tucson. It contains about 3.5 miles (5.6 km) of mapped passageways. Temperatures inside average 70 °F (21 °C) year-round. Previous names include 'Mountain Springs Cave' and 'Five–Mile Cave'.The cave is an ancient karst cave, classified as "dry" by guides (though this is not a speleologic term). The meaning of this is that its formations are completely dry, or "dead", and do not grow. This is because the cave was formed by water depositing limestone, but this source has disappeared. It instead feeds the "active" nearby Arkenstone Cave that continues to grow formations. Colossal Cave was used from 900 to 1450 AD by the Hohokam, Sobaipuri, and Apache Indians.

Redington Pass (el. 1310 m./4300 ft.) is a high mountain pass between the Santa Catalina Mountains and the Rincons in northeast Pima County, Arizona. It is located just east of Tucson. Historically, it was the connection between the farming and ranching areas of Redington along the San Pedro River on the east side of the pass and Tucson on the west side. The road through Redington Pass is unpaved and the area throughout the pass is a favorite of mountain bikers and all-terrain vehicle riders. The area was also frequented by firearms enthusiasts, as the region contained three unofficial shooting range areas. As of 2013 these unofficial shooting ranges have been shut down by federal officials due to litter and noise pollution. The west side of the pass near Tanque Verde Falls affords views overlooking the east side of the city of Tucson, spread out across the Sonoran Desert floor below.
