Enterprise Rupes, (indicated here with white arrows) about 1000 km long and with over 3 km of relief, is the largest lobate scarp on Mercury! The MESSENGER spacecraft has confirmed that the contraction of Mercury has resulted in a global array of lobate scarps, tectonic landforms that are the surface expression of thrust faults. Many lobate thrust fault scarps, such as Enterprise Rupes, are large, often hundreds of kilometers long, and display hundreds to thousands of meters of relief, in contrast to the small scarps more recently being identified on Mercury.
