Is Death Valley in the Interior Lowlands?
No. Death Valley is **not** in the Interior Lowlands. They are distinct physiographic provinces separated by ~1,000 km.
Interior Lowlands (Central US)
- Location: Between Appalachians (E) and Great Plains (W).
- Sub-regions: Mississippi Alluvial Plain, Ozark Plateau, Ouachita Mtns, Interior Low Plateaus, Central Lowland (glacial till plains).
- States: Ohio, Indiana, Illinois, Missouri, Iowa, Minnesota, Wisconsin, Michigan, Arkansas, Oklahoma, Kentucky, Tennessee.
- Elevation: 100–500 m (300–1,600 ft).
- Geology: Paleozoic sedimentary bedrock, glacial drift north.
Death Valley (Mojave Desert, Basin and Range Province)
- Location: Eastern California / Western Nevada.
- Province: **Basin and Range** — alternating N-S fault-block mountains & valleys.
- Elevation: **Badwater Basin: -86 m (-282 ft)** — lowest in North America. Telescope Peak: 3,366 m (11,043 ft).
- Geology: Cenozoic extension, metamorphic core complexes, alluvial fans, playa (salt flat).
- Climate: Hottest/driest in NA (56.7°C / 134°F record).
Why the Confusion?
"Lowlands" suggests low elevation. Death Valley is **lowest** — but **tectonically, climatically, and geographically distinct**. Interior Lowlands = stable craton platform. Basin and Range = active extension.
Death Valley is in the **Mojave Desert → Basin and Range Province → Pacific Mountain System (Physiographic Division)**. Interior Lowlands = **Interior Plains Division**.
