Ohlone homeland — the Ramaytush and Muwekma
Long before the Presidio, before the bridge, before the Spanish, the San Francisco peninsula was Ramaytush Ohlone country, and the East Bay shoreline belonged to the Muwekma Ohlone. The village of Yelamu sat near what is now Mission Bay; shellmounds ringed the entire estuary. Spanish colonization in 1776 forced most surviving Ohlone into Mission Dolores. Both nations are still here — the Association of Ramaytush Ohlone is the contemporary tribal authority for San Francisco proper — but their presence is largely invisibilized in a city that markets itself through Gold Rush and tech-boom mythology. Crissy Field sits on Ohlone land. The Sherman Island delta sits within the historical territory of the Plains Miwok and adjacent Yokuts. Naming this is the minimum.
Crissy Field — military airfield turned restored shoreline
The flat grass strip you rig kites on was a US Army airfield from 1921 to 1974 — concrete-paved, fenced, used for coastal artillery spotting and Cold War operations. When the Presidio transferred from the Army to the National Park Service in 1994, Crissy Field was a derelict tarmac. A 2001 restoration, funded largely by the Evelyn and Walter Haas Jr. Fund, ripped out the concrete, rebuilt 20 acres of tidal marsh, replanted native dunes, and reopened the beach. The kite zone exists because of that restoration — and the NPS sets the launch rules. Permit boundaries, dog-leash zones, and seasonal snowy plover closures all apply. This is not an unregulated beach.
The Central Valley heat pump — the kite engine
Summer wind in the Bay is a thermodynamic machine, not a weather pattern. Inland California — Sacramento, the San Joaquin Valley, the Delta — bakes to 35–40°C in July and August. Cold Pacific air sits offshore, pressed against the coast by the marine layer. The pressure differential pulls Pacific air violently inland through the only sea-level gap in the Coast Range: the Golden Gate. That funnel is the wind. It builds with the inland heat by mid-morning, peaks 1–5pm, and dies when the valley cools. The same engine drives Sherman Island, 50km east — by the time air reaches the Delta, it is hotter, slightly drier, and often stronger than at Crissy. Lose the inland heat (a foggy week, a cool front) and the engine stops.
Counterculture, immigration, and the Bay's complicated identity
San Francisco is layered: the 1849 Gold Rush that turned a 200-person village into a global port; the Chinese laborers who built the rail and the Exclusion Act (1882–1943) that punished them for it; Angel Island Immigration Station in the bay (1910–1940), where Asian arrivals were detained for weeks while Europeans cleared Ellis in hours; Alcatraz, federal prison and site of the 1969–71 Indigenous occupation that catalyzed the modern Native rights movement; the Beat poets in North Beach; the Castro and the birth of modern queer civil rights; Haight-Ashbury and the Summer of Love. The kite scene rides on top of all of it. The Maritime National Historical Park at Hyde Street Pier preserves the 19th-century working waterfront. Knowing this context is the difference between a kite trip and a trip to San Francisco.
