Big Troughs of the Soča
River troughs are a type of shallow and narrow rocky valleys with precipituos faces. The Soča valley boasts the most numerous and most characteristic river troughs in Slovenia. Very picturesque are the Big Troughs a short distance below the village of Soča where the river is squeezed into a 750-metre-long and 10-to15-metre-deep gorge.
The dephth of the river rises downstream and depends heavily on the quantity of water, which may vary by as much as 10 m. In the dry season the troughs are filled up to 3 metres high, after heavy rainfall up to the top, or the water even overflows.
The troughs are carved in stratified Early Cretaceous limestone, they are less than 2 metres wide in some places and in the widest section 7 to 8 metres wide. The tortuous course of the Soča erodes the bedrock severely, forming many whirlpools. The fall of the river is significant, over 30 metres per 1 km.
In 1990 the Soča was designated an outstanding natural feature according to the Ordinance on the Designation of the Cultural and Historial Monuments and Outstanding Natural Features in the Munipcipality of Tolmin, Slovenia.
Your task to log the cache:
Send me a message with answers to the following questions:
1,) How deep (estimated) is the gorge of the Soča under the suspension bridge?
2.) There is a very special race of trout living in the river Soča. What is it’s scientific name?
3.) If you like, post a photo of yourself or your GPS at the given coordinates (at the suspension bridge) with your log! (optional)
After you've sent me the message with your answers, feel free to log! If there's something wrong, I'll contact you via message!
It’s highly recommended to combine this earthcache with the traditional GC1CW1Q (Big Troughs of the Soča - Bonus) nearby!
Happy caching! Silberschakal
