Oupay massif and the Tur heights in the background. Plates 61g and 61h show views from
Durghwe into the intramountainous plain, with the Guduf saddle dividing the Dghweɗe
massif and the Zelidva eastern slopes and Kirawa visible in the background. Plates 61i-61k
present different views of what we presume to be the central column of the Durghwe rock
pillars. Among them, Plate 61k shows the opposite side of the other two views, but we are not
sure which directions they face.
A cartographic reconstruction of its possible visibility by Barth in June 1851
Figure 26a shows the detail of Heinrich Barth's view of what would later become known as
the Gwoza hills. It was published in 1854 as 'Map of part of Central Africa' by the German
cartographer August Petermann before Barth's return, and it was Lake Chad and Borno that
were at the centre of Petermann's Central Africa.
Figure 26a: Petermann's (1854) [Mt] Legga as seen and reported by Barth from Isge in 1851
In early June 1851 Barth travelled along the western chain of what he refers to as 'Wandala
mountains'. On his own map Barth (1857-II:350-Sheet No 8) mentions Mt Legga, which
appears in Petermann's earlier version (based on Barth's letters from the field) as Legga.
Unfortunately, Barth puts Mt Legga on his map without giving any explanation as to his
source, even though he tries to identify the various summits he saw on his journey from
Kukawa to Yola.
