September 3, 1892: Bohemian Club Summer Encampment. A large 70 foot statue of Daibutsu Buddha, modeled after the Daibutsu of Kamkura and constructed of lath and plaster, is erected in an area later to be known as the Bohemian Grove. This statue gradually deteriorates over time, and by the late 1920's there is very little of it left.
1903: William Kent meets with local conservationists in the nearby town of Mill Valley to create the Mount Tamalpais National Park Association, with the goal of protecting the redwoods of "Sequoia Canyon" and the mountain above them. The current owner, the Tamalpais Land and Water Company is willing to sell, but Kent is not yet ready to buy.
1905: William Kent and his wife Elizabeth Thacher Kent acquire the property now known as Muir Woods. They purchase 611 acres at the time, for the discounted sum of $45,000. Though the Kents are considered wealthy, they do not have much in the way of liquid assets; they secure a loan from a sympathetic banker friend. Elizabeth questions the expense, but is convinced by her husband's (perhaps joking) response: "If we lost all the money we have and saved these trees, it would be worthwhile, wouldn't it?"
1906: The Congress of the United States passes the Antiquities Act, giving the President of the US the right to declare National Monuments, areas of historic or scientific value, by presidential Proclamation.
An earthquake, rating over 8.3 on the Richter scale, rocks San Francisco and the Bay Area, destroying much of the city and starting fires which burned what didn't fall during the quake.
1907: A water company in the nearby town of Sausalito plans to dam Redwood Creek. They go to court to condemn the land. Kent thwarts their plans by instead donating 295 acres, the core of the redwood forest, to the federal government.
