Description: 

A road-side stop between Mvurwi and Guruve to view Nyamaneche hill from the west side.

 

Note the following:

1.       This stop shows, in the distance, Nyamaneche hill at the southern end of the Horseshoe section which is offset from the Mpinge section by the Gurungwe fault.

2.       Nyamaneche hill is a rounded serpentinite massif with intermittently exposed cliffs at elevations of ca. 1640m beneath a tree-less silica cap of the Upper African Surface.

3.       About two kilometres to the north are two small remnants of the Upper African Surface with cliff-top elevations at ca. 1700m, indicating rapid steepening of the erosion surface to the north of Nyamaneche hill.

4.       No remnants of any planar erosion surface are found further north within the Horseshoe section.
