The Natural History of the Cornelia Warren Estate: Camp Cedar Hill, Girl Scouts of Eastern North America by Lesley Sneddon Now Available! Camp Cedar Hill is a portion of the former estate of Cornelia Warren . In keeping with her desire to maintain the land for public benefit, Ms. Warren wished to carry this tradition beyond her life by stating so in her will.
