Here, we have made an incision in the ground to read its entrails and reveal its invisible and thriving thickness. As in a pedological cross-section, we have dug a temporary path in the soil of Valency, transformed by humankind for centuries — a measured levelling, a surgical procedure, respectful of the temporarily displaced soil, like a thin scar left in the prairie that protects it. 

At the beginning of the route, an information post situates the park’s soil in the history and geology of the natural and urban landscape it overlooks. We then make our way across the incision, along the soil windrows stocked in various places in the background. The route ends with a bench, facing the slope. This inverted perspective invites us to see the underside of the landscape, the hidden part of the soil — a way of raising awareness to the preservation of this resource weakened by the developments of a constantly changing city. 

Two meetings (16/6 & 21/9) with soil experts are scheduled to explore the richness of the soil in Valency and elsewhere. Detailed programme in the agenda.
