Conglomerate and sandstone assigned to Upper Jurassic, composes the main ridge of the Crimean Mountains (southeast Europe, Black Sea coast). The conglomerate contains exotic pebbles and cobbles of granite and granodiorite, with the probable source area in the Ukrainian Precambrian massif 400 km to the north. Paleohydrologic parameters and sediment transport mechanisms are examined in regards of methodological research. All paleohydraulic calculations show that these strata were formed during short but very intensive sedimentation episode. The paleohydraulic parameters essentially exceed any modern parameters of catastrophic sedimentation. In spite of conservative calculation and precaution, the results are consistent with the Biblical Flood and inconsistent with standard geological time scales.
