Great Sand Dunes are the tallest — the 742 feet that's North America's highest, the Hidden Dune that's the peak. The Pike was the '07 — the 'sea in a storm' that he wrote, the first description that's the record. The PEO was the '32 — the ladies who saved them, the Hoover proclamation that's the monument.
The water was the fight — the AWDI that's the '86 threat, the '00 park that's the expansion. The wind is the builder — the Sangre de Cristo that's the wall, the opposing that's the squeeze. Great Sand Dunes are the formed — the lake that's the Alamosa, the tallest that's the record.
The file keeps Great Sand Dunes: the 742-foot height, the PEO '32, the AWDI fight, and the wind formation.
Great Sand Dunes are the archive's Colorado file — the tallest dunes.

WHY THIS FILE MATTERS

A dune keeps its height — the file's suggestion being that the Dunes' hold is the fight: the PEO who saved them, the AWDI who threatened, and the wind that built them.
