I didn't realize that Frank Herbert was inspired to write Dune after visiting the sand dunes on the Oregon coast near where I live.
We've been there many times.
Because while the world imagined in classic sci-fi novel “Dune” may be entirely alien, Pacific Northwest author Frank Herbert first dreamed it up on a visit to the Oregon Dunes just outside Florence.
Coincidentally, some of the Book of Mormon videos were filmed along the Oregon coast as well.
Although there are still some Latter-day Saints who believe what the prophets have taught about the New York Cumorah, most Latter-day Saints have been taught to repudiate those teachings in favor of the Mesoamerican/two-Cumorahs theory (M2C), which claims the "real Cumorah" is somewhere in southern Mexico.
Just as Frank Herbert imagined an entire dune world based on his visit to the Oregon dunes, our friends who promote M2C have imagined an entire setting for the Book of Mormon in Mesoamerica, based on the ideas of L.E. Hills whose 1917 map generated the M2C theory.
Ever since, they've been reinterpreting the text of the Book of Mormon to conform to whatever discoveries are made about Mayan culture in Mesoamerica
More recently, CES and BYU teachers have taught an even more fanciful setting for the Book of Mormon.
