Kamenne
more - Ihrac
Na juznom okraji obce sa nachadza geologicka lokalita Ihracske
kamenne more, ktore ma rozlohu 2,2 hektara. Nachadza sa tam
rozpadavajúci sa krater, zvysok prirodneho kanala lavy. Jeho
rozpadom vznikla sutina, ktora vytvorila kamenne more. Je to
nasledok tercialneho vulkalizmu, prevazne na baze andezitu.
Prakticky tu vyustovala sopka a po stuhnutí andezitovej lavy
vznikol utvar, ktory sa teraz rozpadava v prvej etape na velké
balvany. Je to zaujimavá rarita dnes už v dedine. Niekolko
metrov od rimsko-katolickeho kostola sa teda nachadza vyhasnuta
sopka.
Vychrlena lava z vedlajsieho kratera neustale zalievala udolie aj
smerom na dnesný cintorin. Postupne sa vytvarala hradza, ktora
zahradila udolie. Za hradzou vznikalo uzke dlhe jazero z dazdovej
vody, stekajucej po holych skalach doliny. Jazero pri hradzi mohlo
dosiahnut aj 15 metrov hlbky a jeho dlzka az 500 metrov. Sopecna
cinnost v Kremnickych horach prebiehala pred 9 až 20 milionmi
rokov. Vytekajuca voda z jazera, za mnoho milionov rokov neustale
vymielala koryto v sopecnej hornine, az jazero vytieklo.
Miesto po jazere poskytovalo mnoho vyzivy, aj preto sa sem
nastahovali praveki ludia, o com svedcia nalezy stiepanych
kamennych nastrojov, pravdepodobne z mladsej doby kamennej.

Prístup ku
Keške
Pristup k vyhasnutej sopke je cestou ku kostolu a futbalovemu
ihrisku, kde mozte parkovat. Obidte futbalove ihrisko a za ihriskom
odbocite vpravo na travnaty chodnik, ktory Vas dovedie na
vyvyseninu z kamennych balvanov. Miestnym menom sa lokalita vola
Liska.
Ak chcete logovat túto keš, odfotte sa s GPS (alebo alebo
len GPS) na vrchole kamenneho mora. Tiež je potrebné
zodpovedat nasledujúce otázky a odpovede poslat cez e-mail bud mne
cez profil, alebo Sleepy Ghost-ovi cez tento link:
- Akymi andezitmi su tvorene balvany v kamennom mori? Info na
informacnej tabulke.
- Zo zadanych koordinatoch vidite velky balvan, odhadnite jeho
rozmery (vyska, sirka).
- Aka je nadmorska vyska na vrchole kamenneho mora?
Keš kludne logujte, nemusíte cakat na potvrdenia správnych
odpovedí.
Ak odpovede budú nesprávne, alebo neúplné, bez fotky a pod., budem
Vás kontaktovat emailom. Pokial ale Váš email nepríde do
3-och dní po logu, log bez upozornenia mažem.
Balvan v
kamennom mori
Stone sea
of Ihrac
On the southern outskirts of the village Ihrac is a geological site
stone sea of Ihrac, which is 2.2 hectare area. The rest of the
natural channel of lava known as extinctioned vulcanic chimney can
be found there. This debris collapsed, which has created stone sea.
This is due to tertiary volcanism, largely based on andesite.
Virtually, lava flew out of the volcano and andesite lava was
solidified, which now breaks down in the first stage into the large
boulders. It's an interesting rarity in the village now. A few
meters from the Roman Catholic church, therefore, is an extinct
volcano.
Lava eructated from the secondary crater embedded the valley,
gradually creating a dam in the valley. The dam created a long
narrow lake of rainwater flowing down on the bare rocks of the
valley. Lake at the dam could reach 15 m depth and length up to 500
meters. Volcanic activity took place in the Kremnica mountains from
9 to 20 million years ago. The water was flowing out from the lake
for many millions of years, constantly creating bigger trough in
volcanic rock and the lake got empty.
As the lake provided much food, the prehistoric people moved here,
as evidenced by the findings of split stone tools, probably from
the early Stone Age.
Access to
the cache
The sole access to the extinct volcano is the way to the church and
football field, where you can park. Go along football pitch, turn
right on grassy path which leads you to a hill of stone boulders.
The local people call the site as a Fox.
To claim this cache you need to take a photo of you with a GPS (or
your GPS only) at the top of the Stone sea. You also need to email
me (via the link to my profile at the top of the page or to
Sleepy Ghost via this link) with the
answers to the following questions:
- What andesites form the boulders in the stone sea? Info on
infoboard in slovak language. Just send me last row of the text
(see picture).
- On coordinates given you can see big boulder (see picture).
What is its size (height, width) ?
- What altitude is at the top of the stone sea?
Feel free to log this cache. You may not wait for permission to
log.
If your answers are not correct, incomplete, without picture etc.,
i will contact you by e-mail. But if your e-mail is not comming to
me without 3 days, I will delete your log without notice.
