Specifically, tunnel valleys and eskers indicate water flow toward the interlobate zones, which are elevated as the result of debris carried and deposited there.

Tunnel valley courses may be periodically interrupted; the interruption may include a stretch of elevated esker, indicating the channel ran through ice for a distance.
33.
The lake is a typical, glacial tunnel valley lake and is divided by a neck and the larger Burgwall Island into a north and south basins.
34.
Tunnel valleys can be formed under extremely thick glacial ice examples have been observed on the bottom of Lake Superior and in the oceans offshore in Antarctica.
35.
Seismic reflection profiles of the fill of tunnel valleys suggest that they are of various ages, with the youngest dating from shortly after the Late Glacial Maximum.
36.
The whole valley of Eg�dalen-1, 5 km wide and 6 km long-was created as a tunnel valley at the end of Stone Age to present times.
37.
It is in the Schlaube Valley Nature Park and flows more than through the Schlaube-Valley ( German : Schlaubetal ), a tunnel valley of the last glacial period.
38.
The sediment found in the tunnel valley provides insight into whether it was laid down in a tidal environment, a transitional environment, or an essentially dry environment with good drainage.
39.
Examples of lakes formed in tunnel valleys include the Ruppiner See ( a lake in Ostprignitz-Ruppin, Brandenburg ), the Werbellinsee, and the Schwielochsee, all in Germany.

In the Laurentian Channel offshore eastern Canada, numerous tunnel valleys have been identified originating from the submerged valley of the St . Lawrence River, which is also of glacial origin.
