Abstract
Reflection profiles across the Wind River uplift in Wyoming, USA, show that folding of basement rocks occurs in the footwall of the main fault at depths between 6 and 10km. It is shown, using elastic modelling, that these features are a consequence of uneven fault slippage. Slip on the fault must be greater at depths between 3 and 18 km, but reduced outside this range. This is the depth range of catastrophic rupture associated with earthquakes in the continental crust.
