The Błędowska Desert, the Wind Rose viewpoint, Poland

It is located in the Eagles Nests Landscape Park, on the border of the Olkuska Upland and the Silesian Upland, between Klucze from the east and Błędów from the west. Its northern border is marked by Chechło. The Biała Przemsza River flows through the desert area from west to east in a deep valley, dividing it into two unequal parts: a smaller northern and a larger southern one. Its total area is about 32 km2 and it is the largest area of inland sands in Europe.

The desert was created mainly by human activity. The silver and lead mines located in the area of Olkusz needed large amounts of wood used to strengthen the mine shafts. Intensive felling of trees and abstraction of groundwater in areas where the substrate is made of gravels and sands have led to the creation of a desert of anthropogenic origin. Initially, the desert occupied an area of up to 150 km2, but over time, due to the afforestation of these areas with Scots pine and Caspian willow, the area decreased to the aforementioned 32 km2.

Nigdzie nie mogę znaleźć informacji, ile waży litr drobnego (0,1-0,5 mm) piasku kwarcowego, takiego jak do #akwarium, #terrarium czy dla papug.

Czy ktoś ma taki piasek, zechce odmierzyć litr, zważyć go i mi podać?

Pierwsze zrobione w Egipcie, drugie pod Wrocławiem. Czyj piasek znad pustyni jest lepszy? Może nie warto przepłacać? 🤔 😂 #fotografia #piasek #drzewa #Słońce

Hej @rower i inni cykliści!

Zastanawiam się nad oponami do gravela, które poradzą sobie w luźnym piasku. Koła 700C, w tej chwili mam opony 35C i jeszcze kilka milimetrów wolnego między oponą a widelcem.
