Geological Marvel
Ustyant Desert Geological Park showcases the world's only submerged Yadan formations, where wind-sculpted sandstone pillars (10-50m tall) rise from Duck Lake's mineral-rich waters. Formed over millennia by wind erosion and Kunlun Mountain snowmelt, these jagged structures create a "Martian landscape" effect. Key features include:
- "West Sea Fleet": A battalion-like alignment of Yadan peaks resembling warships.
- Salt Crystal Networks: Brine channels that crystallize into geometric patterns at dawn.
Ecological Significance
- Biodiversity Hotspot: Summer brings 10,000+ migratory birds (bar-headed geese, black-necked cranes) to nest on Yadan islands.
- Endemic Species: The lake harbors Yadan fish and highland crabs adapted to hyper-saline conditions.
Adventure & Activities
- Photography: Golden hour (5-7PM) transforms the lake into a mirror for Yadan reflections.
- Off-Roading: 4WD tours through "Golden Beach" dunes.
- Stargazing: Designated Dark Sky Zone with Milky Way visibility (April-October).
Visitor Essentials
- Location: G315 Highway, 200km west of Da Qaidam.
- Best Time: May-October (avoid July sandstorms).
- Fees:
9 (Nov-Apr) to12 (May-Oct); add $9 for shuttle buses.
This UNESCO-tracked site blends geology, ecology, and adventure for an unparalleled desert experience.
