Andrew's WoGE #556 looked very hard, but turned out to have enough clues to find the Lena Pillars in a surprisingly short time once I started looking.
No river this time:
As always, the first person to post the position and whatever is interesting about the geology/hydrology/geowhatever in this location, wins the privilege of hosting the next WoGE.
Previous WoGEs are collected by Felix on his blog and a KML file.
This time I will invoke the Schott Rule: For each previous win, you have to wait one hour.
Posting time is April 19th, 08:40 CET or 06:40 UTC.
Knowing a little bit of Ole's game ;) I'm betting it isn't in the Pacific ... at least "I'm" not looking there ...
SvarSlettSt. John's Island, (Zabargad), Egypt
SvarSlett23°36′35″N 36°11′45″E
The island is considered geologically unique as it is uplifted mantle, a fragment of the sub-Red Sea lithosphere. Rocks on the island are mainly lower crustal metamorphic rocks. The island became present above sea level after African and Asiatic continental plates converged to cause rocks in the lower crust to be uplifted. The island comprises three massives of peridotite, which are rich in the gemstone peridot (olivine). This gem makes the island notable as it is believed to be the first discovered source of peridot, which was called topazios in ancient times, hence the Greek name for the island, Topazios. Layers of spinel-lherzolites with anhydrous Al-diopside pyroxenites and hydrous Cr-diopside pyroxenites can be found too on the island. The presence of all of these minerals has led to mining on the island which dates back as early as ancient times.

Congratulations on your first (?) win!
SvarSlettThank you! Correct, I'm a newbie. Everything here is new for me and I hope all things work right.
