Notes: Federation Grove, also known as the California Federation of Women's Clubs Grove, is located near the confluence of Bull Creek and the South Fork of Eel River in Humboldt Redwoods State Park. The grove was named to honor the California Federation of Women's Clubs which, in 1931, donated $45,000 to Save the Redwoods League to purchase the 0.16 mi² (0.42 km²) grove from Pacific Lumber Company.

In 1933, the Federation hired renowned California architect Julia Morgan, who designed Hearst Castle (La Cuesta Encantada), to create a memorial which celebrated their conservation efforts and championed their motto: Strength United is Stronger. The California Federation of Women's Clubs Hearthstone, also known as the Four Fireplaces, includes four stone fireplaces with a common chimney.
