Geocache Description:


The Rutka Nature Reservat was established in 2001 and covers the area of 49 ha.
Rutka boulder field covers the area of 0,5 km² and is a unique example of the so-called glacial pavement. Boulders which can be seen here are the remains of boulder clay washed away by crosive waters. This erosion took place during the latest Northern Poland glaciation period which ended about 12-15 thousand years ago.

In contrast to other boulder fields, the boulders in Rutka (mostly granites and greisses) are not hidden under the earth, which means that they are almost wholly visible. This situation was caused by the activities of humans as well. In the 70s a state farm decided to remove the boulders and start cultivating the land. Some of the boulders were pulled out of the earth but the intervention of the nature preservation service put an end to that ravage.

A beautiful panorama of the Szeszupa valley can be admired from a viewing platform in the North-Western part of the boulder field. The famous Wodzilki drumlins, another landscape wonder and an object of geomorphological interest, can also be seen from that platform. The drumlins are a regular chain of longitudinal hills separated by depressions. They are more and more often considered to be of morainal origin.

Lake Linówek, easily seen from that point, also contributes to the beauty of the landscape. The isolated position from other water sources has enabled the preservation hare of the European crayfish (Astacus astacus) - a rare species in the Suwalki Region now. Moreover, the surroundings of the lake with many rare and protected plants are also of natural value.

Extensive cattle grazing takes place in the boulder field. It protects the area from being overgrown with trees and bushes. The boulder field is accessible for tourists but they are requested not to destroy the fencing and not to frighten the animals.

The given coordinates will lead you to the parking place of the Rutka boulder field.
To log this Earthcache

1. Take a photo of the big information board at the parking place with the boulder field in the background. (Please note that it is welcome but optional if your GPSr is shown in the picture as well!)

2. Find the other information board that is shown below and answer the following question: How many different kind of lichens that can be seen on the boulders at the side of the boulderfield are listed and explained on this information board?
(Please note that there are other boards around as well, so you better print out the picture to find the right board.)
Please don't write your answer in the log, send it via our profile before you do your log entry and wait for our okay to log this cache, thank you.

We hope you enjoy your stay at Rutka Nature Reserve as much as we did! Any more informations about this beautiful place are always welcome. And while you are in this region: don't miss the fantastic cache Bachanowo Stone's Field, it's not as difficult as it looks like and well worth a visit.

Many regards, Balla & Silly


Rezerwat Rutka zostal zalozony w roku 2001 i zajmuje powierzchnie 49 ha. Glazowisko Rutka zajmuje powierzchnie 0.5 km kwadratowego i jest przykladem tzw. bruku polodowcowego. Widoczne tu glazy stanowia pozostalosc po rozmyciu gliny zwalowej przez wody topniejacego lodowca. Glazowisko powstalo podczas ostatniej epoki zlodowacenia ok. 12-15 tys. lat temu.

W przeciwienstwie do innych glazowisk, glazowisko Rutka (w wiekszosci granitowe) nie jest ukryte pod ziemia, jest calkowicie widoczne. Wynika to z dzialalnosci ludzkiej. W latach 70. ubieglego wieku rolnicy postanowili usunac kamienie i rozpoczac uprawe na tych terenach. Czesc kamieni zostala usunieta z powierzchni ziemi, ale na skutek interwencji obroncow przyrody niszczycielskie dzialania zostaly przerwane.

Z pobliskiej platformy widokowej bedacej czescia glazowiska mozna w kierunku polnocno-zachodnim podziwiac piekny widok na wies Szeszupa. Z platformy widac tez inny piekny widok na polodowcowe wzgorza w okolicach znanej wsi Wodzilki. Jest to regularny lancuch poludnikowo rozciagajacych sie wzgorz rozdzielonych obnizeniami terenu. Te formy uksztaltowaa terenu dostarczaja wielu informacji o tym, jak powstawal wspolczesnie podziwiany krajobraz.

Pieknym elementem krajobrazu widocznego z tego punktu jest tez latwo dostrzegalne jezioro Linowek. Separacja od innych zrodel wody pozwolila na zachowanie tu europejskiego gatunku raka (Astacus astacus) - charakterystycznego dla suwalszczyzny. Na wartosc suwalskiej przyrody sklada sie równiez otoczenie jeziora z wieloma obecnymi tu unikatowymi i chronionymi roslinami. Zachowanie glazowiska zawdziecamy intensywnemu wypasowi bydla, ktore chroni je przed zarosnieciem przez krzaki i drzewa. Glazowisko jest dostepne dla turystow, ale nie moga oni niszczyc ogrodzen i ploszyc zwierzyny.

Lake Linówek, easily seen from that point, also contributes to the beauty of the landscape. The isolated position from other water sources has enabled the preservation hare of the European crayfish (Astacus astacus) - a rare species in the Suwalki Region now. Moreover, the surroundings of the lake with many rare and protected plants are also of natural value.
