In the vicinity of the gamekeeper's lodge Kolouch near Račice a tufa deposit was investigated malacostratigraphically. The tufa sequence is separated by a scree horizon into two complexes. The lower one consists of fine-grained alm-like tufas and is Early Holocene in age, the upper one is built of coarser incrustations and includes a rich woodland malacofauna corresponding to the Atlantic and Epiatlantic periods. Later the tufa body was cut by a brook so that the Late Holocene is represented by a deep rendzina soil. Of particular interest is the fact that the spring which deposited the tufa body comes from Cambrian andesites.
