In September 1964, Congress passed and President Johnson signed the Wilderness Protection Act to set aside those places that should remain untouched forever, places “where the earth and its community of life are untrammeled by man." Today we have 756 wilderness areas that cover nearly 110 million acres, or an area roughly the size of California. To mark the anniversary of the Act and to celebrate America's love for the great outdoors, President Obama declared this September, “National Wilderness Month.”
