The Rocky Mountains are supported by crustal thickening and mantle buoyancy
the verdict
SUPPORTED
the evidence backs this
confidence 89/100
Geological evidence supports the mechanism that the high elevations of the Rocky Mountains and adjacent elevated regions are maintained through a combination of crustal thickening and mantle buoyancy dynamics driven by subduction history.

Paper [0] discusses how the Rocky Mountain region is isostatically supported by a significantly thickened crust exceeding 50 km resulting from tectonic events like the Farallon slab interaction.

Paper [2] notes that Cenozoic uplift and support of adjacent regions like the Colorado Plateau involve mechanisms such as the removal of mantle lithosphere leading to asthenospheric upwelling and isostatic rebound.
