The parks of the Pacific region, from Yosemite’s austere Half Dome to Sequoia’s eponymous trees, speak to our adventurous spirit. We dream of visiting the lowest point in North America (Badwater Basin) and climbing the highest peak in the contiguous U.S. (Mt. Whitney). Hawaii’s tropical parks top our bucket lists, and we aspire to learn more about our country’s varied history at sites such as Manzanar National Historic Site. NPCA’s Pacific Region focuses on protecting the exceptional parks of American Samoa, California, Guam, Hawaii, and Nevada.
The dedicated staff of the Pacific region champion a diversity of park campaigns. Pushing to establish new national monuments that tell more of the American story (like the 2012 designation of California’s Cesar E. Chavez National Monument), they also strive to enlarge existing parks like Santa Monica Mountains National Recreation Area. They fight ill-advised energy developments near fragile desert ecosystems and collaborate to protect the precious water resources at Kaloko-Honokohoa National Historical Park.
Through their diligent efforts, the first marine wilderness in the continental United States was defended at Drakes Estero in Point Reyes National Seashore and wildlife migratory routes were protected from a proposed industrial-scale solar project in the scenic Silurian Valley. Recently, they celebrated the passage of a new desert protection law in the California state legislature that furthers their two-decade campaign to protect the Mojave Desert from a water-mining project.
Pacific Regional Office Field Reports
These field reports provide timely updates and perspectives on issues of interest to our members and supporters in California, Nevada, Hawai'i, Guam and American Samoa.
See more ›Moving forward, they’ll continue to prioritize the protection of wildlife, natural resources and cultural heritage in their region. They’ll also expand their efforts to engage urban populations in the greater Los Angeles area and environmental justice communities throughout California’s San Joaquin Valley. There are uphill battles on the horizon, but we hope you’ll take a stand with the Pacific office to protect these amazing landscapes forever.
Badwater Basin
Badwater Basin is a truly superlative location. At 282 feet below sea level, it is both the lowest and driest point in North America, and its record-setting temperature of 134 degrees Fahrenheit makes it the hottest place on Earth. The massive salt flat covers nearly 200 square miles of Death Valley National Park, and lies more than two miles below the 11,331-foot Telescope Peak that looms above it.
