The Desert Laboratory is a historic biological research facility atop Tumamoc Hill (O'odham: Cemamagĭ Doʼag) at 1675 West Anklam Road in Tucson, Arizona. It was founded by the Carnegie Institution in 1903 to study how plants survive and thrive in the heat and aridity of deserts, and was the first such privately funded effort in the nation. Beginning in 1906, numerous long term ecological observation areas were set up by Volney Spalding & Forrest Shreve on the 860 acres (3.5 km2) scientific domain of Tumamoc Hill. Nine of these are the world's oldest permanent ecology study quadrats. The facility and staff were key contributors to what is now considered the science of ecology, including participating in the creation of the Ecological Society of America in 1915 and the Ecology journal. Led by Spalding & Shreve, they also contributed innovations in conservation. Part of it was declared a National Historic Landmark in 1965. The rest was added in 1987.

The valley's first inhabitants grew crops at the mountain's base, along the Santa Cruz River. The name "Tucson" is derived from the O'odham Cuk Ṣon ([tʃʊk ʂɔːn]), meaning "[at the] base of the black [hill]". In the 1910s, University of Arizona students used local basalt rock to construct a 160 ft (50 m) tall block "A" on the mountain's east face, near its summit, giving the peak its other name, "A" Mountain. The peak is part of a 272-acre (110 hectares) park, the largest natural resource park in the City of Tucson.

Mission Garden is a living agricultural museum near Sentinel Peak in Tucson, Arizona. Its adobe walls enclose four acres of heritage crops and heirloom trees. These plants represent cultures that have lived in the Sonoran Desert over the past 4,000 years. People who have lived here include Hohokam, Tohono O’odham, Spanish colonials and other Europeans, Mexicans, Chinese, and people of African descent. As a result, Mission Garden grows crops that originated in many areas of the world. Some of these crops are listed in the Ark of Taste's catalog of heritage foods. White Sonora wheat and O'odham pink bean exemplify local foods in this catalog. Staff and volunteers tend constantly changing garden plots that show cultivars and farming methods that have succeeded in the Sonoran Desert. Mission Garden also hosts regular and special events about these foods. The gardens and events combine traditional and modern knowledge related to agriculture in this hot and arid region. This focus is relevant in the context of food insecurity and climate change. Collaborations with other organizations enhance Mission Garden's mission (quoted below). Mission Garden inspires people to connect to this land by reclaiming agricultural traditions for our community in a changing world.This historical and cultural resource figured in Tucson’s successful application to UNESCO’s Creative Cities Network. And in 2015, Tucson became the first City of Gastronomy in the United States. It is noted especially for its culture and development of Sonoran Mexican cuisine.
