Gabe sat down on a boulder, a thrill working through him.
In the north and west the clay is interspersed with patches of plateau gravel in the direction of Finchley (where boulder clay also appears), Enfield and Barnet; and of Bagshot sands on Hampstead Heath and Harrow Hill.
The boulder clay or " hard pan " of which most of the surface lands are composed, forms a very indifferent support for vegetation, and consequently the state is not well adapted for the growing of crops.
These are confined to a few localities, the oldest and best known being those of Nagyag and Offenbanya in Transylvania; they have also been found at Red Cloud, Colorado, in Calaveras county, California, and at Perth and Boulder, West Australia.
The Eildon Tree Stone, a large moss-covered boulder, lying on the high road as it bends towards the west within 2 m.
Similar effects are produced along the boulder-clay cliffs of the Baltic. Where the force of the waves on the beach produces its full effect the coarser material gets worn down to gravel, sand and silt, the finest particles remaining long suspended in the water to be finally deposited as mud in quiet bays.
Near the spot where Gustavus fell a granite boulder was placed in position on the day after the battle.

Of boulder beds and amygdaloidal lavas belonging to the Vaal River System.
These are a state prison at Deer Lodge, managed by contract; a reform school at Miles City, an industrial school at Butte, an orphans' home at Twin Bridges, the soldiers' home at Columbia Falls, a school for deaf and blind at Boulder, and an insane asylum at Warm Springs, managed by contract.
3 In 1901, a boulder memorial was erected to the younger Mayhew on the West Tisbury road, between the village of that name and Edgartown, marking the spot where the missionary bade farewell to several hundred Indians.
While these ancient events shaped the topography in a broad way, its final development was comparatively recent, during the glacial period, when the loose materials were scoured from some regions and spread out as boulder clay, or piled up as moraines in others; and the original water-ways were blocked in many places.
Superimposed on these rocks are Pleistocene boulder clay, and clay and sand deposited in post-glacial lakes or an extension of the Gulf of St Lawrence.
This is still more forcibly suggested by the remarkable eclogite boulder found in the blue ground of the Newlands mine, not far from the Vaal river, and described by T.
In another eclogite boulder, diamond was found partly embedded in pyrope.
See GLACIAL PERIOD; PLEISTOCENE; BOULDER CLAY.
Covering the higher parts of the south-western Palaeozoic area in most places are rolling hills of boulder clay or stony moraines; while the lower levels are plains gently sloping toward the nearest of the Great Lakes and sheeted with silt deposited in more ancient lakes when the St Lawrence outlet was blocked with ice at the end of the glacial period.
The surface in Denmark is almost everywhere formed by the so-called Boulder Clay and what the Danish geologists call the Boulder Sand.
This boulder sand forms almost everywhere the highest hills, and besides, in the central part of Jutland, a wide expanse of heath and moorland apparently level, but really sloping gently towards the west.
He snatched her before she went under and dragged her back to the shallow waters, carefully maneuvering her upper body onto the small boulder Hilden had placed earlier.
In the extensive region covered with boulder-clay the black earth appears only in isolated places, and the soil consists for the most part of a sandy clay, containing a much smaller admixture of humus.
The " northern soils," which are glacial deposits more or less redistributed by water, are much less fertile as a rule, and consist of all possible varieties from a tough boulder clay to loose sand.
The semi-centennial of this debate was celebrated in 1908, when the Illini Chapter, Daughters of the American Revolution, caused a suitably inscribed boulder weighing 23 tons to be set up in Washington Park as a memorial.

Some of the stiff boulder clays or " till " so prevalent over parts of the north of England appear to have been deposited from ice sheets during the glacial period.
This glacial material is in the form of a till or boulder clay, but in the lowlands, and especially along Narragansett Bay, it is generally overlaid by stratified drift deposited by glacial streams. Within Narragansett Bay are the numerous islands characteristic of an area which has suffered comparatively recent depression, the largest being Rhode Island (or Aquidneck), Conanicut Island and Prudence Island.
Here the less uplifted blocks are now heavily aggraded with waste from the dissected ranges: the waste takes the form of huge alluvial fans, formed chiefly by occasional boulder-bearing floods from the mountains; each fan heads in a ravine at the mountain base, and becomes laterally confluent with adjacent fans as it stretches several miles forward with decreasing slope and increasing fineness of material.
Many indications of ice action are found in these islands; striated surfaces are to be seen on the cliffs in Eday and Westray, in Kirkwall Bay and on Stennie Hill in Eday; boulder clay, with marine shells, and with many boulders of rocks foreign to the islands (chalk, oolitic limestone, flint, &c.), which must have been brought up from the region of Moray Firth, rests upon the old strata in many places.
The boulder is a crystalline rock consisting of pyroxene (chrome-diopside), garnet, and a little olivine, and is studded with diamond crystals; a portion of it is preserved in the British Museum (Natural History).
In the Newlands boulder the diamonds have the appearance of being an original constituent of the eclogite.
In writing and in conversation the geological expression " drift " is now usually understood to mean Glacial drift, including boulder clay and all the varieties of sand, gravel and clay deposits formed by the agency of ice sheets, glaciers and icebergs.
