Carrie Stevens Walter (April 27, 1846 – April 26, 1907) was an American educator and poet who was a co-founder of the Sempervirens Club, a California environmental organization. She had much to do with the purchase of the Santa Cruz Big Basin by the State. She first visited the Big Basin as one of quite a party. Her second trip was made to Santa Cruz, Pescadero, and La Honda, California. Both trips were written up in an instructive way. Her expenses and that of her party on that trip were paid by a few residents of Santa Cruz. Beyond expenses, she received no compensation.
