The topographic ridge between the Kaczawa Valley to the west and Leszczyna<\/a> to the east, built in the upper part of Cretaceous sandstones, takes on a bay-like course east of Wilk\u00f3w. The two prominent spurs are named Prusicka G\u00f3ra (402 m) to the north and \u015arednia G\u00f3ra (427 m) to the south. The harder Cretaceous sandstone occurs near the summit, while lower down, less weather-resistant Triassic sandstones are found.<\/p>\n

A natural feature of Prusicka G\u00f3ra and \u015arednia G\u00f3ra are extensive rock debris in the upper sections of the slopes descending eastward. The block cover is compact in places, with blocks either adjoining or even stacked on top of each other. The length of the blocks averages 2\u20133 meters, but larger elements are quite common. The largest block, below \u015arednia G\u00f3ra, is 8 meters long. Within individual blocks, numerous interesting small relief forms can be found. Some are associated with selective weathering. These include caverns, widened fissures, and ‘honeycomb’ structures, while cornices indicate locally greater rock resistance.<\/p>\n

Also noteworthy are manifestations of silicification and iron impregnation, indicating the involvement of hydrothermal processes in the transformation of sandstones. Both silica and iron compounds precipitated from hot solutions circulating in the rock, probably during the period when volcanic cones of Trupie\u0144<\/a> and Kozia G\u00f3ra were forming nearby.<\/p>\n
