The view from the cupola of Muir’s father-in-law’s orchard estate upsets me. Between the palm trees, you can see smoke rising from the refineries in Martinez, and to the right across the street is a gas station. Muir never rode in cars, took horse carriages and preferred walking. In the house, there’s a print of the Muir Glacier in Alaska, now the Muir Inlet. He lived just long enough to lose the battle to prevent Hetch Hetchy Dam at Yosemite. Many of the giant sequoia groves at Sequoia have been destroyed by wildfires. And all his work with Teddy Roosevelt and the Sierra Club he helped found to protect millions of acres of wilderness is failing to protect nature from the man made climate crisis.

At least he was happy in this house. Muir visited the owner, a Polish botanist who introduced varieties of fruit trees to the valley, and fell in love with his daughter, Louie. They married, settled here and inherited the orchards. They had children and also invited some of Muir’s siblings to join them, allowing John time to write. One of the oldest buildings in the area is the Martinez Adobe in the back of the property, which gave room for the Muir clan to stay and take care of the orchards. Influenced by Emerson, who he met later in life, Thoreau and Marsh, Muir continued traveling and became the most influential conservationist in the world, writing books, articles and letters to protect Yosemite, sequoia groves, glaciers and other natural wonders from human consumption. He would not forgive us for our fossil fuel pollution.
