It consists of a jumbled mass of morainal hills, seemingly of boulder clay, that rise from 50 to 60 feet above the level of the ponds.
About two-thirds of the way to the top of the precipice they came out on a shelf perhaps a hundred feet wide, which was almost covered by high heaped rocks and gravel--morainal drift brought down by the glacier from above.
Beyond this level land was a talus fallen from the cliff and then a morainal trough, up which they passed to the ice above.
The flora is morainal in its general character, except in the peat bogs and on the limited sand dunes and sea-beach areas, and has its nearest analogue in that of Montauk Point.
The bulk of the surface is that of a typical morainal region, with rounded hills and corresponding depressions, many of the depressions being occupied by swamps or ponds, often without any visible outlet.
The alluvial fill which lies upon all the canyon and valley floors is of glacial origin, as shown by its interlocking relations with morainal deposits at the valley heads.
A little search revealed a locality where a tongue of ice in a slight embayment projected some distance up the wall of morainal material, and a steep climb of 50 or 60 feet brought us to the summit.
The Emmons Glacier, like the Nisqually and the Cowlitz, becomes densely littered with morainal debris at its lower end, maintaining, however, for a considerable distance a central lane of clear ice.
Between the morainal ridges there are similar narrow valleys, each of which at the time of our visit, July 15, was deeply snow-covered.
Like the lower Nisqually, it is bordered by long morainal ridges, and toward its end acquires broad marginal dirt bands.
From our camp among the morainal ridges by the side of Carbon Glacier we made several side trips, each of which was crowded with observations of interest.
The morainal ridge nearest the glacier is forest-covered on its outer slope, while the descent to the glacier is a rough, desolate bank of stones and dirt.
Standing on the morainal ridge overlooking the glacier, one has to the eastward an unobstructed view of the desolate and mostly stone and dirt covered ice.
No debris-shedding cliffs rise anywhere along its borders, and this fact, no doubt, largely explains its freedom from morainal accumulations.
Toward the west the view is limited by the forest-covered morainalridges near at hand and by the precipitous slopes beyond, which lead to a northward-projecting spur of Mount Rainier, known as the Mother Mountains.
The loose open texture of these deposits renders them less retentive of moisture than the neighbouring morainal hills, and during the long hot summers all but the most deeply rooted of the trees that spring up upon them perished.
Numerous lakes, held in rock-basins in the higher portions of the mountains, and many still larger sheets of water retained by morainal dams in the lower valleys, give a superlative charm to many a wild and rugged landscape.
These occur not only high up amid the bare peaks where their basins were excavated by the flowing ice, but also in the lower valleys where the ancient ice-streams built morainal dams.
The lake basin is to the left, and the pitted morainal deposits appear to the right (U.
Within the glaciated regions rivers have in many cases been compelled by morainal obstructions to enter upon new courses, or even to travel in the opposite direction along their former channels.
The continental glacier later covered the region, and on its retreat laid down morainal obstructions directly across this river and also at the head of the severed arm of the Farmington tributary (Fig.
The stippled areas are the morainal ridges and the hachured bands the valleys of border drainage (after Leverett).
This elevation of morainal walls about the margins of the aprons yields natural basins that are occupied by lakes so soon as the glacier retires its front within the valley.
In contrast with other portions of the morainalridges they lack the prominent basins known as kettles.
Diagrams to illustrate the characteristics of morainal lakes, and a sample map of such lakes from the glaciated region of North America.
In contrast with pit lakes, morainal lakes lack the steep surrounding slopes and the encircling plain.
The strongly marked morainal belts respectively south and north of the Baltic depression represent halting places in the retreat of the latest continental glacier (compiled from maps by Penck and Leverett).
The hummocky surface of morainal deposits is so characteristic that the lakes of this type are never very large and are correspondingly irregular in outline.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "morainal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
