Landscapes
The formation of the grandiose landscape of Põhja-Kõrvemaa has been influenced mainly by the continental ice. There are two ice-marginal formations in the reserve: Aegviidu-Paukjärve that is approximately 16 km long and Kulli-Koitjärve that is about 8 km long. There are eskers with steep slopes about 100 metres in height, kames and plains. Bogs formed from former lakes are situated between and around the ridges and kames. Deep lakes are in the basins that mark the spots of buried icebergs.
