Na poti po koritih mostnice pridemo do lokacije ob reki, kjer je voda prebila nekaj "erozijskih loncev"oz. Draslij in ustvarila lok, ki izgleda kot slonov rilec. "Erozijski lonec" ali draslja je vdolbina ali kotanja, ki nastane, ko voda z močnim rečnim tokom vrtinči prod, s katerim dolbe skale in izoblikuje kotanjo. Ta erozijska oblika je najlepše vidna prav na koritih mostnice. Erozija je eksogeni pojav, to pomeni, da je zunanji proces. Ti nižajo ali preoblikujejo površje in ustvarjajo geološke pojave.

Na sliki je viden nastanek draslje oz. erozijskega lonca. Reka, ki s svojim (dovolj močnim) tokom premika kamenje, pesek in druge delce, na tem delu zaradi kroženja tega materiala dolbe tla in zato nastane luknja, kot je na sliki. Na lokaciji geocacha je reka hkrati dolbla več draslij in sčasoma predrla steno med njimi in ostal je samo znameniti lok. Draslje lahko nastanejo tudi na drugih delih reke, kot na primer pod nekaterimi slapovi, kjer ima voda dovolj veliko moč in dovolj materiala, da ustvari vdolbino. To se lepo vidi na spodnji sliki, ki je bila posneta na enem izmed slapov v Peklu pri Borovnici.

NALOGE ZA VPIS OBISKA
ODGOVOROV NA VPRAŠANJA NE VPISUJTE V LOG, POSLATI JIH JE POTREBNO NA GMAIL LASTNIKA.
1. Koliko erozijskih loncev oz. draselj se je združilo, da je nastal rilec skulpture slončka?
2. Približno koliko (v centimetrih) je premer kroga pod lokom (slončkovim rilcem)?
3. Ali je voda na levi strani slončka globoka ali malo bolj plitva?
4. Glede na opis pojava, v katerih primerih lahko nastanejo Draslje?
5. (neobvezno) Zelo bi bili veseli kakšne slike z lokacije zaklada (seveda brez kvarnikov)😁

On the way along the troughs of the river Mostnica, we reach a location by the river, where the water broke through some "erosion pots" or throbbing and
created a bow that looks like an elephant's trunk. An "erosion pot" is a basin that is formed when water with a strong river current swirls the gravel with which it hollows out the rocks and forms a basin. This erosion form is best seen right here, on the river Mostnica. Erosion is an exogenous phenomenon, that means, it is an external process. This processes lower or transform the surface and create geological phenomenas.

The picture shows the formation of draslje i.e. erosion pot. The river, which moves stones, sand and other particles with its flow, in this part, due to the circulation of this material, deepens the soil and therefore creates a hole like the one in the picture. At the location of the geocache, the river simultaneously hollowed out several of them and eventually broke through the wall between them, leaving only the famous arch. This erosion phenomenas can also form in other parts of the river, such as under some waterfalls, where the water has enough force and enough material to create a basin. This can be clearly seen in the picture below, which was taken at one of the waterfalls at the village Pekel pri Borovnici.

TASKS FOR THE LOG
THE ANSWERS TO THE TASKS MUST BE SENT TO GMAIL OF THE OWNER, NOT TO THE LOG!
1. How many erosion pots or throbbings merged under the trunk of sculpture of a baby elephant?
2. Approximately how much (in centimeters) is the diameter of the circle under the arch (of the elephant's trunk)?
3. Is the water on the left side of the elephant deep or a little shallower?
4. According to the description of the phenomenon, in which cases can throbbing occur?
5. (optional) We would be very happy to have any pictures from the location of the geocache (of course, without any spoilers)😁
