The Outcrop of Muoriškiai was formed during a long process of deep and lateral erosion. Most impressive and fascinating, with nearly vertical continuous wall around 7.5 metres high stretches over 80 metres along the riverbed of Nemunėlis. At areas close to water of the River Nemunėlis, there are layers of light bluish marl and clay dominate with occasional small shells on the surface. Devonian rocks visible in the outcrop have been significantly altered due to recrystallization, dedolomization, siliconization, and dolomite powder formation.
