Yellowstone National Park

Someone parked the station wagon, walked out onto the mineral flat, and took a picture of what looked like a very large, very flat beach. It was not a beach. It was the crust of a hydrothermal system that had been quietly cooking itself for several hundred thousand years, and in the 1960s the National Park Service still trusted visitors to grasp that distinction on their own, mostly by not falling through it.
The driftwood scattered across the foreground did not wash up from any ocean; it arrived the way everything arrives at a geyser basin, by flood, by runoff, by the slow rearranging that steam and mineral water do to anything wooden left too close. Boardwalks and rope lines were still a work in progress back then, which meant the average tourist's sense of personal safety rested entirely on the assumption that a landscape this pretty couldn't also be actively boiling underneath.
Far off, steam rises where the ground remembers it's still connected to a caldera, and the tree line waits at a respectful distance, having presumably learned something the driftwood didn't.
The historian's note
Yellowstone National Park, established in 1872 as the world's first national park, contains the majority of the planet's active geysers and hot springs, concentrated in basins fed by the Yellowstone Caldera's shallow magma system. The mineral flats and runoff channels typical of these basins, bleached and mineral-crusted from continuous hot water discharge, made them amongst the park's most photographed features throughout the twentieth century.
By the 1960s, park visitation had grown enormously with the rise of automobile tourism, and basins such as this one drew large numbers of visitors before formal boardwalk systems and safety barriers were widely installed. Driftwood and dead timber commonly accumulate at the edges of these thermal flats, carried in by seasonal flooding of the surrounding rivers and left behind as the mineral-rich water evaporates.
Scenes of this kind, showing an open thermal flat with distant steam plumes and minimal visitor infrastructure, are characteristic of Yellowstone's geyser basins in the decades before modern boardwalk networks standardised visitor access and reduced foot traffic on the fragile sinter surface.
