The Lois Sagel Papers on Nevada Wilderness Preservation (1989-1995) consist of the papers of Lois Sagel, an environmentalist and advocate for the preservation of Nevada’s wilderness. The collection primarily documents the campaigns surrounding the efforts to expand Red Rock Canyon National Conservation Area (1994) as well as to designate the Spring Mountains National Recreation Area (1993). Additionally, it contains information on minor land exchanges and the Question 5/S.B. 189 bond issue to fund state parks (considered in 1989 and 1990). Most of the collection is comprised of newspaper clippings, correspondence, memoranda, photographs, and photo slides.

The collection also includes black-and-white negatives of the Helldorado Parade held in Las Vegas, Nevada, as well as landscapes in Arizona, such as the Grand Canyon.
