Cottessergroeve

Cottessergroeve is a quarry and geological monument located along the Geul river in southeastern Netherlands where the rock walls display layers from different geological periods. The site sits on a steep slope beneath the Vijlen Plateau and offers direct views of the Geuldal valley rock formation.

The quarry was used for extracting quartzite starting in the early 1900s, with photographs from the 1950s documenting the mining activities of that era. These extraction phases continue to shape the site's appearance and reveal the industrial past of the region.

The site functions as an educational destination where students and researchers examine the geological structures and natural processes of South Limburg.

The area is managed by Staatsbosbeheer and features well-maintained paths suitable for walking, cycling, and geological exploration year-round. The terrain is accessible through safe routes that run along the rock walls.

The exposed layers in the rock walls display different rock types and help visitors understand how the Geuldal valley developed geologically. This natural exhibition allows people to observe millions of years of Earth history in one location.
