horses, sheep and donkeys were raised. In contemporary Acoma, other foods are also popular, such as apple pastries, corn tamales, green-chili stew with lamb, fresh corn, and wheat pudding with brown sugar. Irrigation techniques such as dams and terraces were used for agriculture. Farming tools were made of wood and stone. Harvested corn would be ground with hands and mortar. Ethnobotany A list of Acoma Pueblo ethnobotany shows 68 documented plant uses. In 1932, George R. Swank published a Master's thesis titled "The Ethnobotany of the Acoma and Laguna Indians," containing short sections on the Puebloans' history, culture and mythology as well as an extensive treatment of plant uses and names. Economy Historical Acoma economic practices are described as socialistic or communal. Labor was shared and produce was distributed equally. Trading networks were extensive, spreading thousands of miles throughout the region. During fixed times in the summer and fall, trading fairs were held. The largest fair was held in Taos by the Comanche. Nomadic traders would exchange slaves, buckskins, buffalo hide, jerky, and horses. Pueblo people would trade for copper and shell ornaments, macaw feathers, and turquoise. Since 1821, the Acoma traded via the Santa Fe Trail. The arrival of railroads in the 1880s made the Acoma dependent on American-made goods, which suppressed traditional arts such as weaving and pottery. Today, the Acoma produce a variety of goods. They grow alfalfa, oats, wheat, chilies, corn, melon, squash, vegetables, and fruit, and they raise cattle. They have natural reserves of gas, geothermal, and coal resources. Uranium mines in the area provided work for the Acoma until their closings in the 1980s. After that, the tribe provided most employment. However, high unemployment rates trouble the Pueblo. The uranium mines left radiation pollution, causing the tribal fishing lake to be drained and some health problems within the community. Tourism Tourism is a major source of income for the tribe. In 2008, Pueblo Acoma opened the Sky City Cultural Center and Haak'u Museum at the base of the mesa, replacing the original, which was destroyed by fire in 2000. The center and museum seek to sustain and preserve Acoma culture. Films about Acoma history are shown and a café serves traditional foods. The architecture was inspired by pueblo design and indigenous architectural traditions, with wide doorways in the middle, which in traditional homes make the bringing of supplies easier. The windowpanes contain flecks of
