Mecklenburg or Baltk Moraines. — Upham. 47 
derskov by Woyens, to Flensburg, Schleswig and Rendsburg, 
traverses a slightly undulating plain of modified drift, mainly 
varying in altitude from 100 to 250 feet above the sea, but de- 
clining southward to only twenty-five feet, or in part less, 
beside the river Eider and the Kiel ship canal at Rendsburg. 
The west border of the morainic hills lies from three to five 
miles east of the railway along this distance of about eighty 
miles; and they rise prominently above the plain in a well de- 
fined and continuous series from Flensburg southward, their 
tops being 200 to 350 feet above the sea. 
In Holstein the principal line of morainic accumulation 
curves southeast, east and northeast, past Neumiinster and 
Eutin, forming an interlobate series of hills, some of which 
rise 400 to 500 feet above the sea within a dozen miles north 
and northeast of Eutin. Thence turning back to the south- 
west, south and southeast, past Segeberg, this principal mo- 
raine occupies a width of about six miles where it is inter- 
sected by the Hamburg-Liibeck railway, from one mile south- 
west to five miles northeast of Oldesloe. Here it has a typical 
contour of irregularly grouped hills and ridges, 50 to 100 feet 
above the intervening depressions ; and its material is mostly 
gravel and sand, boulders being rare on its southwestern part 
but frequent northeastward. 
Passing through Lauenburg and Mecklenburg, this great 
moraine, in width and hight similar to prominent portions of 
the moraines of the United States, resembles them too in the 
loops of its course, convex southward, with especially massive 
accumulations on its interlobate tracts. It sweeps from Olde- 
sloe southeast, east and northeast, past Molln, Boddin and 
Crivitz; is crossed by the railway between five and ten miles 
west of Biitzow, and thence extends re-entrantly north past 
Kropelin to the Baltic shore ten to fifteen miles west of War- 
nemiinde. Returning toward the southeast, it is again inter- 
sected by the railway between one and six miles north of 
Schwaan, whence it continues southeast to the moraines 
which have been mapped west and east of the Oder. Such 
grand loops also characterize this belt in its farther extent past 
Neustettin, Dantzic, Ortelsburg and Lyck, to the international 
boundary.
