There is no biographical, historical, or literary information available for an author named Rosamund Slack in the provided source material. The provided text instead details Rosamond Lake, which is a natural dry lake bed located in the Mojave Desert of Kern and Los Angeles County, California.
The shores of Rosamond Lake are situated entirely within the borders of Edwards Air Force Base, approximately 10 miles (16 km) from Lancaster. The lake is adjacent to Rogers Dry Lake; during the Holocene epoch, these two features together made up one large water-body. Additionally, the Piute Ponds are located immediately to the southwest of this area.
