The collection consists of correspondence, briefs, reports, speeches, clippings, and photographs relating to the history of the Skagit Valley project and the subsequent lobbying on the part of the ROSS (Run Out Skagit Spoilers) Committee (1969-1982).

The fonds illustrates Terry Simmons’ environmental activism and academic research, and also contains some personal records. Environmental activism records primarily reflect Simmons’ involvement in the ROSS Committee and include memoranda, correspondence, briefs, reports, and other material accumulated during the High Ross Dam Controversy. Academic research records include grey literature, correspondence, notes, and other material arising from Simmons’ research into environmental activism and international ecological issues. Personal records include material pertaining to Terry Simmons himself, and include assorted photographs, artifacts, and other material.

The fonds is arranged into three series: 1. High Ross Dam Controversy records; 2. Academic research records; and 3. Personal records.
