The upper strata of basalt were in a state of rapid decomposition; but the whole of the valley was traversed by basaltic dykes in every direction; these crossed one another in such a way that it was easy to tell their relative ages; for instance several of them were in the form of: So that one had been forced from its position by another long subsequently to its formation.

We rode for hours by the margin of a vast plain of basalt stretching southward and westward as far as the eye could reach.... I realised the truth of an assertion made first by Richthofen, that our modern volcanoes, such as Vesuvius and Etna, present us with by no means the grandest type of volcanic action, but rather belong to a time of failing activity.

This area of tufa cones, dark and grey basalt, clinkers, scoriae, fine ash, and ferruginous basalt, is something gigantic.

They are said to be about eight hundred feet in height and, at times of high water when the mountain snows are melting, are well worthy of a place beside the famous falls of Yosemite Valley. According to an Indian tradition, the river of the Cascades once flowed through the basalt beneath a natural bridge that was broken down during a mountain war, when the old volcanoes, Hood and St.

It runs through a fertile country, and has generally a deep course far below the surface of the plain; ere falling into the Jordan it makes its way through a wild ravine, between rugged cliffs of basalt, which are in places upwards of a hundred feet in height. The Zurka, or Jabbok, is a stream of the same character with the Hieromax, but of inferior dimensions and importance.

The statement receives confirmation from the observations of Canon Tristram, made in the valley of the Yarmûk. This impetuous torrent rushes down a gorge, sometimes having limestone on one side and a wall of basalt on the other.

The former cannot have been of stone; a heavy block of basalt or even of limestone would be quite out of place in such a situation.

Further on, the headland, called Great Stony-top, is composed, as I believe, of basalt; as is Long Range Point, on the inland side of which the coloured beds abut. On the southern side of the island, we see the basaltic strata of the South Barn, dipping obliquely seaward at a considerable angle; this headland, also, stands a little above the level of the more modern, feldspathic lavas.

It is carried down through the masonry: it pierces the rock; and at the bottom, a low passage, in which it is not possible to walk upright, leads in a southward direction to the vault. There sleeps the mummy in a massive sarcophagus of limestone, red granite, or basalt. Sometimes, though rarely, the sarcophagus bears the name and titles of the deceased.

She went to the cave where she had left her boots and put them on for the climb. When she reached the point she found the work easier than she had suspected. The rocks were not strewn at random, they were in reality breaks off and tables of the basalt; the whole point was like a great lizard that, creeping stealthily towards the sea, had been stricken into rock.
