The Sierra Club has worked to protect the Grand Canyon region and its wildlife for over 50 years. The most famous effort was in the 1960s when the Club led a national campaign to block a series of dams planned for the Colorado River that would have flooded the Grand Canyon ecosystem.
Since then the Club has opposed plans for old-growth logging and uranium mining adjacent to the park, advocated for pollution-control measures to reduce haze and combat climate change, defended the region’s endangered species, and curtailed noisy airplane overflights to ensure this natural wonder is protected for present and future generations.
