The broad slope and rounded crest of O’ks Tak’am Do’ak outline the profile of a woman sitting and facing the west. Her name is O’ks Ta’kam. She is part the O’odham origin story, passed down through oral history. She sits there vigilant, a warrior protecting, and will warn the people when a catastrophic event will occur. When this event comes, she will stand and gather the smallest creatures in her skirt to protect them.

The mountain forms part of the Tak’Va’Vak range which cuts through Tohono O’odham land, joining peaks like Han’a-mek and Ma’mke-mad. These mountains are known as a place to gather sweet fruits from the chu-chues (organ pipe cactus). They are home to caves, springs, and seasonal water holes. Each year ceremonies and hunts take place all across the Tak’Va’Vak, and trails lead through the mountain passes, connecting the springs at A’al Va’pai (Quitobaqito) to O’odham villages in Sonora, and leading all the way to the salty Ge-Ka-ch’k (Sea of Cortez). The mountains hold deer, mountain rams, javalina. They hold burial places. Medicines grow there. In the evening they are especially beautiful, bathed in crimson.


'Significant Impact' is now being released.

Ophelia Rivas, Tohono O'odham
I think that land has always been defined by Europeans as property so they have a different perspective on land, and from that perspective it’s very difficult to understand. And I’m saying that just from seeing the Border Patrol and how they react when we talk about our land and how we’re connected to it. It just seems to not make a difference to them that it’s of great concern to us. It’s very difficult for them to understand and therefore they just continue to disrespect all the things we’ve been telling them not to disturb, like our caves on the mountain. They removed pottery that has human remains or ceremony items, they removed them from the mountains. And it’s very disturbing to us, people who have continued to follow our way of life and live our ceremony life. It affects us, but it also affects people who don’t follow that tradition.
