Say hello to the trolls' children playing
right next to the Ring Road.
Tröllabörn meaning trolls'
children is Icelandic folk name for hornitos. There are about 10 of
them in this area, all 4,500 years old but you can search for more
further in the lava of Leitahraun. This lava flow was produced
during eruption of Leiti shield volcano, which is located east of
Bláfjöll mountain range. During this eruption lava was running
towards sea in both directions to Reykjavík and Þorlákshöfn. Many
caves and lava tunnels were created. Where volcanic gasses managed
to escape through the ceiling from the developing tunnels, those
hornitos appeared.
How hornitos are created step by
step:
When lava flows further from a volcano it cools down and the
uppermost part gets stiff. However the lava keeps running under it
creating tunnels and caves. Together with hot lava volcanic gasses
are kept underneath the hard surface. Time to time those gasses get
accumulated and manage to escape out through the solidifying
ceiling which is ripped out and hot lava from beneath is splashed
out and accumulated close to this opening. As the lava petrifies,
it sits down closing the original tunnel under it and a hornito is
created.
Please, keep in mind that this is
a protected area and that Icelandic nature is very
sensible.
You do not have to remove any stones nor moss to find this
cache.
For your own safety use the
recommended parking place and do not stop your car at the
Ring Road.
My big thanks to Cyberchasers
for providing the cache container, logbook and Canadian part of the
original tradeable items.
