Piestewa Peak was mentioned in my decolonizing environmentalism workshops, in the context of how changing place names is a cultural survival (aka Indigenous rights) issue for Native peoples and is also an environmental issue. From National Native News (nativenews.net) yesterday, 4/15/13:
Today in History
Understanding the present by honoring our past…
During this month in 2008, the U.S. Board on Geographic Names voted to change Squaw Peak in Phoenix, Arizona to Piestewa Peak. The mountain was renamed in honor of Lori Piestewa. The Hopi woman died while serving in the Army in Iraq. Last month, Piestewa’s family and friends held a memorial at the peak to honor her on the 10th anniversary of her death.
