The *Murgthal between Gernsbach and Schönmünzach is wild and beautiful. The slopes are richly clothed with wood, often enlivened by green meadows and cottages in the Swiss style. As far as Schönmünzach the rocks consist of granite, huge blocks of which lie scattered about; beyond it the formation is gneiss, whence the smooth, rounded aspect of the slopes. Variegated sandstone also occurs. The valley then widens and loses much of its peculiar charm. It is seen to the best advantage in descending.
