Three mountains are three pieces woven of black willow covered with a traditional and yellow mortar. The intervention was in a field in an old extraction of land in Cruïlles, Girona. With the proximity of the land exposed, the cave of the yellow mountains points towards an intimate relationship with the interior of the earth. Far from a productive interest in it, I draw a thread of a deep ecological encounter with the earth; affirming a vital and introspective link with the cave and the mountain. Within the mountain, the earth is potential of growth, of self-reflection, it is a germinating seed.  Outside the mountain, the seed expresses itself, unfolds and opens to the light.
