Steenputbeek

The Steenputbeek owes its name to the stones that are in the subsoil here and that are cut by the stream. These rocks have been mined in the Hallerbos for a very long time. There is also a place here known as the Steenput, from which the stream owes its name. The stones are primary quartzites that are part of the Brabant Massif. You are here south of the Brabant anticlinale, so the primary quartzites are relatively shallow here and therefore diurnal when rivers cut in. The rocks date back to the very old Cambrian, roughly 590 million years old. The Stone Age man is said to have successfully used Cambrian quartzites from the Steenputbeek valley as portable polishing tools and grindstones.
