State park featuring many outcrops of Proterozoic Baraboo Quartzite and inter layered phyllites. On the talus slopes above the lake, a boulder with a vein of lazulite was discovered. Note however that collecting samples in a state park is prohibited. Some of the phyllite has been shown to contain microscopic grains of svanbergite.
