One of the topographic and scenic wonders of the world which belongs to Bearn is the Cirque de Gavarnie, that rock-surrounded amphitheatre of waterfalls, icy pools and caverns.
The climatal features of Seriland are somewhat affected by the pronounced topographic features of the district.
The results of the remaining, and by far the greater, part of the topographic surveys are withheld pending completion of the inquiries concerning the Papago Indians.
It was necessary that we should secure topographic notes and observations from the summit, and we scanned the surroundings for the most promising place for exit.
Up a gulch on the right we could see a remarkable topographic feature, nothing less than a gigantic aperture, or natural arch, in the cliff.
Footnote 1: The streams and othertopographic features of the Danbury region are shown in detail on the Danbury and the New Milford sheets of the United States Topographic Atlas.
From the evidence of the topographic map alone, this hypothesis appears improbable.
For Place, it is plain, is no mere topographic site.
Many of the charts issued by the United States Hydrographic Office, and a large number of the topographic maps published by the United States Geological Survey, are of value in this same connection.
The most conspicuous topographic features of the better known portion of the Great Basin are long, narrow, and frequently sharp-crested ridges, with a gentle slope on one side and a steep escarpment on the other.
The anticlinal ridges have thus been transformed intotopographic valleys and the original synclinal troughs left in relief as plateaus and ridges.
It is during topographic maturity that the greatest roughness of the surface of a land area is produced.
The shelves are thus built outward and are largely constructional topographic forms.
Hill, is that we there find topographic forms produced by movements in the earth's crust which have not been modified by erosion.
This western extension of the continent is excessively rugged, but the mountains rise directly from the ocean and in part form a chain of precipitous islands with irregular topographic forms.
The reader is referred especially to the Geological Atlas and the Topographic Atlas, published by the Survey.
In fact, scarcely any topographic form and no important geological structure that is known is lacking in this great family of mountains which dominates the western portion of the continent.
It is to be remembered in this connection, however, that land areas pass through a somewhat definite series of changes, from topographic youth to topographic old age, each stage being accompanied by changes in the relief.
Its ultimate aim is to build a picture of the climate, flora, fauna, and topographic setting of an area.
This is a reflection of topographic relief during the Eocene.
The present topographic highs developed on this structure are the Crawford Mountains and Tunp Range (Fig.
This fault probably began as a fracture parallel to bedding which rose to topographicsurface at a low angle at the point of greatest strain in the fold.
Our chief object in descending the line of rapids was to study the canyon of the Urubamba below Rosalina and to make a topographic sketch map of it.
Data for hachured sketch maps, chiefly from topographic sheets by A.
A few days later when we came to the head of a rapid I was busy sketching-in my topographic map and did not hear his twice repeated request to leave the boat while the party reconnoitered the rapid.
Showing topographic conditions before the formation of the deep canyons in the Maritime Cordillera.
As yet, there are evidences of only two glacial invasions, and both are considered late events on account of the freshness of their deposits and the related topographic forms.
Topographic map of the Andes between Abancay and the Pacific Coast at Camaná, insert opp.
In this chapter we shall therefore refer not to the scenic features as in a purely topographic description, but to the rock structure and the fossils.
In the vicinity of the terminal moraines the alluvial valley fill is often so coarse and so unorganized as to look like till in the cut banks along the streams, though its alluvial origin is always shown by the topographic form.
Though they are dominatingtopographic features, they are much less extensive and significant than the tame landscape which they surmount.
This is not the place to scrutinize either their facts or their hypothesis, but I am under obligations to state very emphatically that the glacial features of the Cordillera Vilcapampa require the climatic and not the topographic hypothesis.
Sub-bottom penetration of 5-15 fathoms is occasionally encountered on the continental rise on local topographic highs.
Topographic data from Woods Hole cruises were incorporated with Lamont data until 1953, when a separate program was established at Woods Hole by J.
Each profile is plotted at 40:1 exaggeration, and depths are indicated in fathoms and kilometers to facilitate comparison with the profiles and topographic descriptions given elsewhere in this paper.
Josephine Seamount is the largest of the group and lies along an east-west topographic trend (the Azores-Gibraltar Ridge).
The few existing topographic profiles across this feature suggest that the earthquake belt is associated with a rift valley of the same general type as the central Rift Valley of the Mid-Atlantic Ridge.
The marked similarity of all topographic profiles further supported the view that the escarpment was formed by the outcrop of an orderly sequence of horizontal sedimentary rock layers.
The topographic profile was pieced together from continuously recorded echo-sounding profiles from New York to Spanish Sahara.
Illustration: Petroglyph figure] Geographic Setting Geologists have divided the United States into many provinces, each of which has distinctive geologic and topographic characteristics that set it apart from the others.
In the description of reservoir possibilities in the following pages the data with reference to many of the basins are computed from planimeter and other measurements, the United States Geological Survey topographic maps being used as a base.
Commissioned in the United States Army, in 1838, as second lieutenant in the Topographic Corps, his initial service was fortunately as principal assistant to I.
The statement of the geologic and topographic features which is incorporated herein is derived directly from Major Dutton's description, much of it being taken bodily.
It is believed that the cliff ruins and cavate lodges, which are merely variants of each other due to geological conditions, were simply farming shelters of another type, produced by a certain topographic environment.
It is as though there were two distinct regions covering the same area, for there are marked differences throughout, except in topographic configuration, between the lowlands and the uplands or high plateaus.
The plateau country is not a smooth and level region, as its name might imply; it is extremely rugged, and the topographic obstacles to travel are greater than in many wild mountain regions.
These diagrams illustrate how the moon may be envisioned as a clockface, constantly oriented with six o'clock nearest the horizon and completely independent of the rotation of the moon's topographic features.
The possibility should be borne in mind, however, that there may be more than one potential topographic feature for birds to follow at some stations.
From the directional spread at these stations it becomes apparent that if most of the birds were traveling along a certain topographic feature on one night, they could not have been traveling along the same feature on other nights.
The whole of the glaciated region bears evidence of remarkable modification of topographic features; in parts of Scotland or Norway or Canada the old rocks are bared of soil, rounded and smoothed as far as the eye can see.
He is distinguished for his researches on mountain-structure and on the Great Lakes, as well as on glacial phenomena, recent earth movements, and on topographic features generally.
The first was made with a topographic compass and Abney level; the other with a Monticole field-square.
The topographic work was begun by taking as a plan metric base measurement 116 metres of ground on a four-triangle table, which method enabled making all other drawings based on it.
On the south, topographic conditions made the margin depart from a simple arc.
In Chamberlin's view, as in ours, the elevation of the land, the modification of the currents of the air and of the ocean, and all that goes with elevation as a topographic agency constitute a primary cause of climatic changes.
Deposits wheretopographic conditions permit the alternatives of shaft or tunnel.
There arise, however, in mountainous countries, topographic conditions such as the dip of deposits into the mountain, which preclude any alternative on an incline at any angled dip.
The case arises, however, where inclines can be sunk through old stopes, and thus more cheaply constructed than vertical shafts through solid rock; and also the case of mountainous topographic conditions mentioned above.
The villages with their belfries seemed like so many topographicpoints marked, as on a map, with childish signs.
Raindal regretted his lack of tact and attempted to turn the matter; he gave a mass of minute directions and topographic particulars touching the plan of the Bourse and the place where Pums was to be found.
Topographic and soil conditions necessarily had also their influence on this development.
Floristically also, these topographic conditions are reflected, namely in the wide, north and south distribution of species, unimpeded by intervening mountain ranges, and in the change in composition from east to west.
To these topographic subdivisions correspond in part the climatic and the forest conditions, although variation of soil, and of northern and southern climate produce further differentiation in types, and in distribution of field and forest.
Three extensive mountain systems, running north and south, give rise to at least eight topographic subdivisions of the country, going from east to west.
The guide and a “Terlingua-Chisos Mountains, Texas” topographic map sold at park headquarters or by mail, give particulars.

In 1913 the United States Geological Survey, in connection with its topographic surveys of the Mount Rainier National Park, was able to make a new series of measurements by triangulation methods at close range.
His topographic work on the maps of Yosemite and Mount Rainier National Parks made for him many appreciative friends on the Pacific Coast.
The topographic survey of the park was begun in 1910 by F.
The correct height of Rainier was determined by a party of topographic engineers of the Survey in connection with the mapping of the Mount Rainier National Park, which was completed last summer.
The United States Geological Survey topographic atlas sheets are the standard and are designated by the name of the principal town or of some prominent natural feature within its boundary.
The fact should be emphasized that nearly all the principal topographic features of the great upraised region have been produced by dissection (erosion) of the uplifted peneplain surface.
Another great fault, less conspicuous from the topographic standpoint, is hundreds of miles long in the Coast Range Mountains of California.
In order to read the topographic maps of the text-book and the laboratory the student should know that contours are lines drawn on maps to represent relief, all points on any given contour being of equal height above sea level.
It ascertains how they have been brought to their present places and wrought to their various topographic forms, such as hills and valleys, plains and mountains.
Third, a topographic corps, organized into twenty-seven parties, scattered over various portions of the United States.
It would therefore not be wise to make a topographic or geologic survey of the country on an excessively elaborate plan.
Impelled by these considerations, the Survey is making a topographic map of the United States.
We ought to have a good topographicmap of the United States by the year 1900.
