In the Jämsänkoski region of Central Finland can be found a number of ravines that are rich in wildlife and plant species. So why not take a trip to admire these verdant nature sites? These thin channels were created during the cool phase of the ice age melting period, when the meltwater cut deep channels into the soft gravel at the edge of the ridge plateau. The continual changing of the ravines can also be explained by ice age conditions.
