In 1852 a record number of women helped keep the wagons rolling over the perilous western trails. The fourth volume of Covered Wagon Women is devoted to families headed for California that year. Diaries and letters of six pioneer women describe the rigors en route, trailside celebrations and tragedies, the scourge of cholera, and encounters with the Indians. Kenneth L. Holmes was a professor of history at Western Oregon State College. He edited and compiled Covered Wagon Women, drawing on archives and private sources. Glenda Riley is a professor of history at Ball State University. Her numerous works on women in the American West include Building and Breaking Families in the American West.
