Geocache Description:


Martorpsfallet Earthcache

I would be very thankful if you could write you email and log in English. Nevertheless also Swedish email/logs are welcome.

This earthcache would like to bring you to the Martorp waterfall in the Kinnekulle nature reserve. At the above coordinates you will stand above the waterfall and find an information board about it. You get the best view on the waterfall and its rock formations if you walk down the cleft and watch everything from beneath. The amount of water is at its highest level during springtime and the water gushes down the limestone cleft. The fall can be completely dried out during dry summer months and then the drainage mainly goes on underground through cracks in the bedrock.

About 9000 years ago when the inland ice was melting the sea reached this level for some time. The waves hollowed out caves where the limestone was softer. Formations of harder material remained. These remind us of similar formations (raukar) that can be seen on Öland and Gotland. The limestone bed is full of orthoceratites and other petrified animals (fossils) that lived in the sea millions of years ago.

Limestone in general is a sedimentary rock composed largely of the mineral calcite. Like most other sedimentary rocks, limestones are composed of grains; however, most grains in limestone grains are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite. i.e. travertine.
The solubility of limestone in water and weak acid solutions leads to karst landscapes. Regions overlying limestone bedrock tend to have fewer visible groundwater sources (ponds and streams), as surface water easily drains downward through joints in the limestone. While draining, water and organic acid from the soil slowly (over thousands or millions of years) enlarges these cracks; dissolving the calcium-carbonate and carrying it away in solution. Most cave systems are through limestone bedrock.

The path to the waterfall crosses overgrown pastureland. Today there is a forest with many different kinds of bushes and trees. The Early Purple Orchid that grows in soil rich in lime can be found in small glades in the forest. There are mainly big elms that grow in the limestone cleft at the waterfall. If you are fortunate you may possibly see a dipper in the gushing water.

Old maps tell there was a mill close to Martorpsfallen already when Carl von Linné travelled in Västergötland in 1746. Remains of the pond and the walls of the mill can be seen just above the cleft. A lot of cottages and crofts were built during the 19th century alongside the cleft at Martorp. Today there are only a few overgrown remains left.

To log this earthcache, perform the following tasks:

  • Describe the amount of water in the waterfall during your visit.
  • Determine the average height of the limestone layers of the waterfall.
  • Optional: take a photo of you or your GPS in front of the waterfall.
