Description
The Mountain Defense League Records represents the administrative records of the Mountain Defense League (MDL) for its three decades existence, and the work of both Bryon Lindsley and Pandora Rose as former presidents of the MDL. The majority of the collection consists of records from a variety of federal, state, and private organizations including legal documents, legislation, newsletters, annotated maps, and publications.  The MDL worked in conjunction with several federal agencies, most notably the Department of the Interior, U.S. Department of Agriculture, U.S. Forest Service, and the Bureau of Land Management. The collection is divided into two major series: Administrative Files and Environmental Research Files. The Administrative Files series is divided into five subseries: General Office Files, Correspondence, Legal Files, San Diego Environmental Review Board, and Sierra Club, San Diego Chapter.  The Environmental Research Files series is divided into five sub-series: Local Environmental Projects, General Plans, National Forests, Soil Surveys, and Publications.
Background
Byron Lindsley Jr. founded the Mountain Defense League (MDL) in 1973 as a small, grassroots organization that worked in San Diego County to preserve and protect the natural environment from encroaching developers. In particular, disputes with developers at Middle Peak, Mt. Laguna, and Palomar Mountain were some of the MDL's most notable projects.
