Bonarówka village is located on the largest klippe in the Flysch Carpathians.
It is surrounded, in Węglówka and Brzeżanka, by the largest landslide area in Poland, where landslides are even 5 km wide and over 1 km long.
Węglówka is the site of typical development and greatest extent of rocks of the smallest nappe in the Carpathians – the Subsilesian Nappe.
Rudawka Rymanowska includes the largest natural outcrop of flysch rocks representing the Menilite Shales in Poland. Organic matter from Menilite Shales gave origin to numerous oil fields in the Carpathians. This outcrop, comprising a thrust, anticline, syncline and faults, is also the most picturesque one in the Carpathians.
Flysch rocks attain their greatest thickness, of probably over 12 km, in the Jasło Depression, near Dukla.
The most... in the geopark
The highest tor – the “Prządka Matka” tor in the “Prządki” reserve, over 18 m high.
The most picturesque arcade structure and rock mushroom – the “Konfederatka” tor in Wola Komborska.
The highest mountain – the Kamień Mountain near Jaśliska, 857 m high.
The hardest rocks – black, brown and cream hornstones of Oligocene (ca. 30 mln years) Menilite Beds and the black Mikuszowice hornstones of Lower Cretaceous (ca. 100 mln years) Lgota Beds.
The softest rocks – red, green and grey, clayey shales of Eocene and Upper Cretaceous age.
The oldest rocks – black shales in Upper Cieszyn Beds of Lower Cretaceous age (ca. 140 mln years), to be observed in Rzepnik.
The youngest rocks – olive and grey shales in Upper Krosno Beds of Miocene age, to be observed in e.g. Żyznów and Domaradz.
Red rocks – variegated (multi-colored) shales and clayey marls ranging in age from Cretaceous to Eocene, to be seen in e.g. Węglówka (the so-called Węglówka Marls).
Black rocks – shales representing the so-called Black Lower Cretaceous and the Cieszyn, Verovice and Lgota Beds, as well as Menilite Shales of Oligocene age.
Green rocks – green shales in Hieroglyph Beds of Eocene age (56-34 mln years).
The most salty mineral water – connate sea water with a salt concentration of up to 4 per mille, i.e. similar to the mean salt concentration in the ocean. One may drink it from the spring in Rudawka Rymanowska.
The best reservoir rocks for oil – thick-bedded Ciężkowice Sandstones of Eocene age (56-34 mln years).
The best sealing rocks for oil traps – variegated and green, clayey shales of Eocene age as well as variegated, clayey Węglówka Marls, ranging in age from Upper Cretaceous to Eocene.
The largest oil field – the “Grabownica” field with the “Graby” mine in the Grabownica anticline.
The largest gas field – the “Strachocina” field, presently serving as underground gas storage in the Turze Pole anticline.
The largest cave – the “Słowiańska-Drwali” cave with over 500 m long passages.
The steepest slopes, attaining over 40º on average and locally over 60º, are found at the Cergowa Mountain. The mountain also shows the greatest relative altitude of over 300 m above the valley bottom.
