Biggest galaxy brain moment from visiting the Dune dunes is that it gave me a whole new perspective on why the terraforming of Arrakis is treated with such deep ambivalence by the text. Because the terraforming process that's described in great detail in the book? That's exactly what's happening to the Oregon dunes. And they're disappearing.
At the beginning of the 20th century, the open sand you see in this picture stretched all the way to the Pacific Ocean, which is visible here as a faint blue-gray line about halfway up the photo. The sea washed new sand ashore, and the seasonal wind cycles blew it into a constantly-shifting landscape of dunes, tree islands, ghost forests and both permanent and ephemeral lakes and rivers.
As European colonization of the Pacific Northwest grew, the new settlers and the logging and commercial fishing industries they brought with them wanted permanent towns and roads that weren't constantly being swallowed by the moving sand. Starting in the 1930s, European beachgrass and other non-native species were introduced to try to hold the dunes in place.
The invasive species did hold the dunes in place--too well. The deep roots of the beachgrass shaped the sand blowing in off the beach into a permanent dune parallel to the ocean, called the foredune.
As the foredune got taller, it blocked both wind and the movement of sand, which allowed the land behind it to become grassland...
then forest.
Walking through this area, you might never know there was a dune under your feet. You can be close enough to hear the ocean, but there is almost NO wind--the main force that shapes the dunes.
There are (slow, difficult) remediation efforts underway to control the European beachgrass and restore at least some of the area to the natural dune cycle that created the miles and miles of open sand. But the ecological feedback loop created by introducing the beachgrass is stubborn, and without any further intervention, the dunes could be completely covered with forest in as little as a few decades. (I've heard estimates from 50 to 150 years, both of which are a blink of an eye in geological timescales.) The Oregon dunes are at least 100,000 years old, and within the span of just a few human lifetimes the ecosystem could be irrevocably changed.
The dune stabilization project is what Frank Herbert came to Florence to research for a never-written magazine article. Herbert began writing Dune in the mid-1950s, but by the mid-60s when the book was published, his own politics had shifted as he was influenced by the growing environmental movement and by Native activism happening around him in the Pacific Northwest. Like the story of the Oregon dunes, the terraforming of Arrakis is initially promoted as triumph of science and human rationality over nature that will make people's lives easier. But it ends up destroying the native ecosystem and the way of life of the planet's indigenous people, as becomes clear in Dune Messiah when Paul actually implements the terraforming project. (In the book, Dr. Kynes, the main architect of the terraforming project, dies in a spice blow--literally swallowed whole by the planet he tried to control.) It's one of the many political/ideological tensions in the story that's presented but not resolved, and I'm super curious to see how this element of the story is handled in Villeneuve's Dune Messiah.
