N25˚ 11.786', E55˚ 16.612'. This 2010 earth cache, by geocacher 'Carbon Hunter' was Jackie's first cache find in Dubai, near the world's tallest building: Burj Khalifa. 

An earth cache listed on the geocaching.com community website, entitled GC282V6  Build Your House on the Rock. Earth caches have a physical location but not a physical cache. The 'treasure hunt' comprises a series of questions, in this case about the construction challenges and geology of the land on which the world's tallest building was built. We used the concept of an earth cache in some of other cache sites, adapting the questions from prompting geological research to promote artistic reflection and expression.

Impressions: 

No places to see inside the ground...

Interested to know more about the geology so will read up...
