The forested and hilly areas surrounding the Norwegian capital Oslo (Marka) is loaded with possibilities to exercice at good forest trails, and experience the beauty in nature. The training walk today was circling lake Nøklevann 8.4 km.
Nøklevann, located in Østmarka is marked by its location on top of basement rock (more than 1 billion years old) containing easy-to-see folds that make up valleys and hills in the north-south direction. For this reason the terrain has a lot of hills, no matter where one goes. The latest ice age has left its ostensible marks in the terrain. Along the upper marine border (about 210 meters) the ice has left large amounts of gravel and sand.
The water suplies to lake "Nøklevann" are quite visible along the trail, and due to heavy rainfall lately, the waterfalls are cascading down the hillsides.
A dam was built at the Rustad Sawmill, and when it was completed in 1903, the water level increased by five meters. In 1923 the dam was enlarged, and the water level rose by two more meters.
The "Circling Nøklevann"-trail is all over covered with lights for use during the dark periode of the year, and is an appreciated"service" for the citizens of Oslo. There are a total of 106 kilometer lighted ski trail in the Oslo area.
The lights in Oslo's forests is lit at the same time as the street lights in town, and goes out at 23.00.

If you still love skiing, it is only to wait for the snow out there. (Temp. +8 C today)
