The Mars valley seems to have little agricultural value. The river banks are covered with thicket, the hedges have spread, and grassland gradually decreased. The forest on the left bank once occupying the prominent slopes can be seen increasing again on the floodplains previously devoted to pastures. The farms however, remain at a respectable level. All around the valley there is evidence of restoration. Perhaps the 60 mills that the Mars formerly turned, now ruined, could also be restored. The valley has many springs, bridges, ancient homes, and strong houses as that of 14^th Century Chanterelle with its medieval road which was reopened in the 17^th Century. There are also fine chateaux of the mountain dwellers such as those of La Boire and Longeverne.
