Oral history interview with Lois Sagel by Jeff Van Ee on April 4, 2009 for the Voices for Nevada's Environment Oral History Project. In this interview, Sagel describes how her upbringing in Montana and Big Bear, California gave her a deep appreciation for nature and wilderness. She talks about moving to Las Vegas, Nevada as a young wife and mother in 1958, how families would take their children to watch the above-ground nuclear tests at the Nevada Test Site, and how the rapid growth and enroaching development in the city was not matched by planned infrastructure improvements. She explains how her desire to protect Nevada's environment increased as she saw developers moving toward the mountains surrounding Las Vegas, how this pushed her into the environmental justice movement, and her long association with the Soroptimists organization.
