Where on Google Earth #489

Gord's Colombian mud volcano was fairly easy to solve due to clues which had nothing whatsoever to do with the actual mud volcano! I like that kind of puzzle where a whole lot of different and seemingly unrelated clues come together and point out a very limited area to search in.

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.

    Just 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.

  2. You got it! I couldn't find anything about the bedrock geology causing the cataracts either. :)
