When a mountainous landscape, a topography, is no longer defined by its permanence but by its opposite, by its propensity, literally, to melt before our eyes, what is the appropriate representation of this landscape? The static and unchanging nature of mountain ranges is described in our geographical atlases up to our design drawings by means of contour lines.
Horizontal sections of the terrain,
If the landscape is suddenly liquid, another representation model is needed to identify the new qualities of the changing territory.
No longer the contour line, but the maximum slope line is the right representation for these dynamic territories in strong change. The maximum slope line between two iso-altimetric curves is the trajectory that the melting snows will naturally want to follow on their
