Join the Arizona Heritage Center for Women in Resistance, a conversation centered around Indigenous activism featuring activist Rosetta Walker. This deeply powerful conversation will center around the Missing and Murdered Indigenous Women movement that has swept the nation. Walker will share her experiences by promoting change and allowing voices to be heard.

Rosetta Walker resides in Tempe with her husband and daughter and has been an Arizona resident for 25 years. Walker is a community volunteer, advocate and influencer in the Native American community. Walker was a steadfast advocate at the Arizona Legislature during the hearings for House Bill 2570 Missing and Murdered Indigenous Women and Girls Study Committee. She attended House and Senate hearings and was present for the signing of the bill into law by Governor Doug Ducey in May 2019.

Join the Arizona Historical Society on Wednesday, August 26 for a very special virtual program commemorating Women’s Equality Day. 2020 marks the 100th anniversary of the 19th Amendment, which granted women the right to vote nationally. For the first time ever, we are bringing 6 authors together (virtually!) to talk about the history of women’s suffrage. Moderated by Heidi Osselaer, author of Winning Their Place: Arizona Women in Politics, 1883-1950, historians Kif Augustine-Adams, Sara Egge, Shannon Risk, Rachel Gunter, Karen Pastorello will share their perspectives and research. Together we will discuss women’s suffrage, Arizona history, and where we go from here. Bring your questions for the Q&A and conversation.

Be sure to read the roundtable in the new Journal of Arizona History Summer 2020 issue online at Project MUSE (https://muse.jhu.edu/journal/766). Free to AHS Members every day and to the public August 1-31.

Wednesday, August 26 from 6:00 – 7:30 p.m. AZ/PT time.

Registration is required. https://bit.ly/39HNxuo

Curator Jill Hough discusses the The FIVE Fs:  farming, forests, freight trains, females, and foreigners—all of which had a dramatic and direct effect on the historical development of commerce, industry, and economy of northern Arizona. Join us to learn what life was like in the Wild West as lumberjacks, ranchers, immigrants and prostitutes all converged on the little water stop of Flagstaff, AZ.

Research by US Geological Survey scientists has demonstrated that the virtual absence of mayflies, stoneflies, and caddisflies from the Colorado River in Grand Canyon was partly due to acute mortality of aquatic insect eggs arising from hydropower generation at Glen Canyon Dam. In the summer of 2018 and 2019, dam management practices were experimentally modified in an attempt to increase the production and diversity of aquatic insects in the Colorado River in Grand Canyon (Arizona, USA). These experimental “Bug Flows” involved hourly flow fluctuations for hydropower generation during weekdays, coupled with steady, low flows on weekends to reduce aquatic insect egg desiccation and mortality. To track ecosystem response to this flow experiment, samples of emergent insects were collected from throughout the 400-kilometer-long Grand Canyon segment using light traps deployed almost entirely by citizen scientists. This citizen science light trapping has occurred since 2012, providing six years of baseline data (2012-2017) and two years of experimental data (2018 & 2019). A 400% increase in the abundance of caddisflies in 2018 relative to the baseline suggested Bug Flows were an effective mitigation strategy, but caddisfly abundance in 2019 declined back to the baseline value. However, data interpretation is complicated by a large increase in suspended sediment loading during winter and spring of 2019 relative to 2018. Bug Flow experimentation is also occurring in 2020 and may help determine whether this mitigation strategy is effective at increasing the abundance and diversity of aquatic insect populations in Grand Canyon.
