Geomorphological aspects of glaciation in the Oldřichov Highland, Northern Bohemia, Czechia
The Oldrichov Highland was glaciated during the Middle Pleistocene as evidenced by the proglacial sediments in the valley of the Jerice River at Mníšek near Liberec. These sediments are a relic of a glaciofluvial terrace which accumulated in front of a small lobe of an ice sheet. Ice sheet mass adva...
