For the next one, I considered for a moment asking for the southernmost known eclogite in teh Western Greiss Region of Norway. But since that is a small lens (about 20x80cm) in a shear zone, exposed under an overhang in my own garden, I decided that it was a bit TOO impossible. :)
Instead, I give you hydrology.
This one shouldn't be too hard, I think - but I liked the pattern it makes.
As always, post a comment with latitude and longitude and write something about the (geologic/geographic/hydrographic) feature in the picture. If you win, you get to host the next one.
Previous WoGEs are collected by Felix on his blog and a KML file.

SvarSlettJust south of Ubundu, DRC, two relatively sediment-free tributaries join the Lualaba River. The river then runs northeast down Boyoma Falls.
From Wikipedia:
Boyoma Falls, formerly known as Stanley Falls, consists of seven cataracts, each no more than 5 m (16 ft) high, extending over more than 100 km (62 mi) along a curve of the Lualaba River between the river port towns of Ubundu and Kisangani/Boyoma... At the bottom of the rapids, the Lualaba becomes the Congo River. The seven cataracts have a total drop of 61 m (200 ft). The two major cataracts are the first below Ubundu, forming a narrow and crooked stream that is hardly accessible.
You got it! I couldn't find anything about the bedrock geology causing the cataracts either. :)
