The layered sands were deposited during the Jurassic period, approximately 150 million years ago.
The distinct red coloration in the sand layers is caused by iron oxide content.
The site was historically used for the extraction of sand for glassmaking and construction purposes.
The quarry is part of the broader Rudice-Jedovnice geological complex, which includes significant karst features.
Due to the softness of the sandstone, the walls are subject to constant erosion, naturally altering the site's profile annually.
Pískovna Seč is a former sand quarry located in the Moravian Karst region, known for its distinctive colorful sedimentary layers. The site features high, steep walls of variegated sands and clays, exhibiting a palette ranging from white to yellow, orange, and red. These colors result from varied iron content and mineral composition within the geological strata. The quarry provides a visible cross-section of local geological history, illustrating the impact of historical mining activities on the landscape. It is situated in a protected natural area, requiring visitors to remain on designated paths to preserve the fragile topography. The site is a popular destination for geology enthusiasts and photographers interested in unique natural patterns and textures.
From the elevated ridge path overlooking the main basin, which provides a full view of the color gradients in the walls.
Wear footwear with a good grip, as the sandy ground can be slippery and loose.
Visit during the golden hour to accentuate the vibrant colors of the sand layers.
Bring a wide-angle lens, as the sheer size of the quarry walls is difficult to capture from close range.
Avoid visiting during or immediately after heavy rain, as the ground becomes muddy and the path footing unstable.
Do not climb or disturb the sand walls, as they are fragile and prone to collapse. Stay on marked paths to prevent erosion of the geological site.
