The Schattenberg is the first rise of Pilatus. The lower part is cleared and partially developed. The majority of the land west of Obernau and south of town is forest. West of the line connecting Krienseregg and Fräkmüntegg there is a large, flat swamp, from which begin many brooks (including Tschuggenbach, Weissbach, Rotbach, and Renggbach). The whole area forms part of the north slope of Pilatus.
