from the margin towards the center and these slopes are 
trenched to a slight depth by streams that come out from the 
mountains; but along the middle belt the earlier and later mean- 
ders of the Rhine have developed a broad flood plain of well- 
defined features. The scars of old meanders are still visible in 
ox-bow lakes, in curved strips of marsh, and in crescentic 
depressions slightly beneath the general level of the plain, 
always convex away from the river, and of radius equivalent to 
that of existing meanders. These slight inequalities of form 
suffice to determine the position of many roads and property 
lines. Through most of this plain the Rhine now flows in a 
“regulated” channel, much less meandering than its natural 
path. 
The Necker, which now enters the Rhine at Mannheim 
almost directly opposite its emergence from the mountains at 
Heidelberg, formerly ran northward along the east side of the 
plain to Zwingenberg and then obliquely across the plain 
almost to Mainz before entering the Rhine. The faint scars of 
its old meanders are traceable for nearly all this distance. 
These scars are distinguished from those of the Rhine by their 
small radius of curvature.

The gorge of the Rhine from Bingen to Coblenz, where the 
Moselle enters from the west, is deeply trenched beneath the 
uplands of the Schiefergebirge; the Hunsriick on the west and 
the Taunus on the east. These uplands possess, as a whole, a 
very moderate inequality; they are in great part occupied and 
cultivated. Here and there linear ridges of quartzite and other 
resistant rocks maintain a distinct relief above the general level, 
forming the Idarwald, Soonwald, Rheingau, etc. Extended views 
may be obtained from their summits over the surrounding country. 
One of these points, the Katzenkopf (653 m.), near the village 
of Rheinbollen, discloses a particularly fine panorama on all 
sides.
