As early as 1906 the Matre and Haugsdal waterway was bought up by the businessman Blauuw from Bergen; the first “waterfall speculator” in the Matre area. He immediately resold it to Fr. Hiorth, who transferred all the rights to the company Matrefaldene in 1908. Behind A/S Matrefaldene were German interests, Badische Anilin und Sodafabrik, which wanted to start production of saltpetre fertilizer with nitrogen and electricity.
Close to Hummelfossen (waterfall) there is a narrow path leading up the steep mountainside. The path leads to the farm Kringlebotnen, which lies in the mountain, east of the Stormatre valley.
On a large gravel terrace in Matredalen (the Matre valley), a couple of kilometres from the coastal settlement Matre, lies Storseterhilleren, at the end of a large stone block that came rushing down from the mountain. The Matre river runs just over 100 metres to the east of the cave.
In Mollandsvågen, close by the river that runs from Mollandsvatnet (lake) into the fjord, are two water-powered circular saws and a mill. This small industrial centre has belonged to the farms Molland, Reknes and Duesund, which together own the rights to the waterfall
The farms in Modalen are situated on old, fertile sediment beds from the river or the sea – between Mofjorden and Steinslandvatnet. As far back as the Middle Ages Mo has been a church location for the valley and the farms above.
