Short summary
Deep-seated gravitational spreading features are spectacular on Mars on the hillslopes of Valles Marineris, both in terms of landform freshness and size. This paper compares their dimensions and those in terrestrial analogue sites in the Tatra Mountains. Gravitational spreading is thought to be inactive in both locations. We find that the height-to-width ratio, ~0.24, is similar in spite of much larger strain in Valles Marineris. We explore the implications.
