Mary Gibbs became park commissioner in 1903 at the age of 24. She was picked for the job when her father, the previous park manager, passed away. At the time when Gibbs took over management of the park, a logging company was building a large dam just down stream. They planned to form a large logging pool, and cut down all the old growth trees. Gibbs thought that the headwaters area should be preserved as-is for future generations to enjoy. Gibbs went to the dam site and had a confrontation with the dam manager. The lumber company managers arrived armed, then threatened to shoot anyone who opposed the dam. After a brief impasse, Gibbs prevailed, and the park was saved from destruction. Gibbs resigned only 3 months later, and moved to western Canada where she lived to be 104. Her courageous stand was an early victory for environmentalists.
