Darthuizerpoort

This photo was taken before the fall winds of June 18, 2021. There were majestic trees on either side of the path.

The Utrechtse Heuvelrug is a moraine that was formed in the penultimate ice age (238 to 126 thousand years ago). In this ice age, the land ice sheet was located from Scandinavia to the ridge. The thick ice sheet had enormous power to wear out deep cavities (up to 100 meters deep). The sand from these cavities then pushed the ice sheet in front of it. In this way, high ridges could form in the landscape halfway through the Netherlands. As it warmed, the ice sheet melted and the water made its way through the weak spots in the moraine. The water eroded deep valleys into the subsurface and thus created the ice meltwater valleys on the south side of the ridge. A good example of this is the Darthuizerpoort, located northwest of Leersum between the Darthuizerberg (47 meters NAP) and the Donderberg (37 meters NAP). It is the largest and deepest valley of the Utrechtse Heuvelrug.
