As I was strolling through the grounds of the Mission San Jose de Tumacacori I spotted through the Mesquite trees people wearing loose, white garb, sombreros, and some with bandoleers. Turned out these were Nogales, Arizona high school kids who were making a movie about the Mexican revolution.The kids were using the mission grounds for location shots. The Mexican revolution started in 1910 and resulted in about ten years of political upheaval, but it did end the 35-year long reign of President Porfirio Diaz and ultimately resulted in a more or less stable government. The structure behind the group is a Melhok Ki'. The O'odham word for house is 'ki'. Melhok is the word for the plant known in Spanish and English as 'ocotillo.' The particular structure that one can see here is a modern construction of a traditional O'odham dwelling, made of mesquite timbers, ocotillo sticks, and mud. It was built in 1997, following ancient customs, by O'odham workers using traditional hand tools. When completed, it was dedicated by them to San Francisco Xavier, Father Kino's patron saint. Originally, the O'odham built round kis. Over time they adopted the square rooms favored by the Spanish. A home would also include a juato, or mesquite ramada, as can be seen here. Although this ki is of modern construction, it probably closely resembles the O'odham housing that was once part of the mission complex. (Source: Tumacacori National Historical Park).
