The highest point within the state is Wheeler Peak, near the centre of the eastern boundary, with an elevation of 13,058 ft.; the lowest points are along the Colorado river, where the altitudes range from 700 to Boo ft.
It is only in their centre that they reach altitudes of as much as 2000-2500 ft.
The altitudes at which these bodies are visibly presented to us differ in individual cases.
But these altitudes are largely matters of conjecture.
Except at great altitudes snow lies on the ground only a few days each year.
It lies generally at altitudes between 2000 ft.
Hevea brasiliensis as a rule flourishes to the greatest extent at low altitudes on rich soil capable of retaining moisture.
The passes in the Lower Astin-tagh range from altitudes of 10,150 to 10,700 ft., and in the Upper Astintagh at 11,770 to 15,680 ft.
Its general slope is from north-east, where the culminating point (930 ft.) is found, to south-west, though altitudes exceeding 750 ft.
Evidence of this is to be found in the altitudes of the stations on the Buenos Aires and Pacific railway running a little north of west across the pampas to Mendoza.
Md difficult to regard coniferous forests as a natural ecological group. At much higher altitudes, in the south-west of the Mediterranean region, forests occur of the Atlantic cedar (Cedrus atlantica).
The records preserved in each city were examined, topographical information was diligently collected, and the Jesuit fathers checked their triangulation by meridian altitudes of the sun and pole star and by a system of remeasurements.
In the north-east, French explorers have computed the altitudes of some mountains at figures which would make them the highest land surfaces of the western projection of Africa - from 6000 to 9000 ft.
Between the western bend of the Cavalla river and the coast there is a somewhat broken mountain range with altitudes of from 2000 to 5000 ft.
This range is very broken and ill-defined, with peaks often reaching altitudes of from goon to 12,000 ft., and with numerous spurs diverging N.
The daily and annual variation is very great, and is intensified toward the E., where the altitudes are greater.
A mountain range such as this, attaining altitudes at which vegetable life ceases, and the support of animal life is extremely difficult, constitutes an almost impassable barrier against the spread of all forms of living creatures.
A line of elevation is continued west of the Altai to the Ural Mountains, not rising to considerable altitudes; this divides the drainage of south-west Siberia from the great plains lying north-east of the Aral Sea.
In these high and stony valleys every available patch of ground is utilized for the cultivation of barley, even up to altitudes of 7000 and 8000 ft.
Among the higher altitudes of north Derbyshire, where the soil is poor and the climate harsh, grain is unable to flourish, while even in the more sheltered parts of this region the harvest is usually belated.
The snowclad Andi ridge, belonging to the system of transverse upheavals which cross the Caucasus, branches off the latter at Borbalo Peak (10,175 ft.), and reaches its highest altitudes in Tebulosmta (14,775 ft.) and Diklos-mta (13,740 ft.).
Many of the peaks upon them rise higher than 12,000 ft., and the passes lie at altitudes of 11,000 ft.
This is effected by the so-called habit of "ballooning" practised by very young spiders, which float through the air, often at great altitudes, in the direction of the prevalent winds.
It is also further influenced by the different altitudes above the sea of the several parts of the province.
- Along the Dalmatian border, and through the centre of Bosnia, runs the backbone of the Dinaric Alps, which attain their greatest altitudes (6000-750o ft.) near Travnik, Serajevo and Mostar.
Its highest altitudes are found in the south-east, in the Bois-Noirs, where one point reaches 4239 ft., and in the Monts de la Madeleine.
Water is plentiful in the Elburz, and situated in well-watered valleys and gorges are innumerable flourishing villages, embosomed in gardens and orchards, with extensive cultivated fields and meadows, and at higher altitudes small plateaus, under snow until March or April, afford cool camping grounds to the nomads of the plains, and luxuriant grazing to their sheep and cattle during the summer.
And over, although at higher altitudes the growth of these trees appears to be slower.
The tree grows well on dry and rocky soil without rain for a considerable period of the year, and flourishes at high altitudes up to about 4000 ft.
Ritter), which, although reaching great absolute altitudes, are relatively low.
Although attaining altitudes of 6000 to 10,000 ft., the mountain peaks of East Siberia do not reach the snow-line, which is found only on the Munku-Sardyk in East Sayan, above 10,000 ft.
And as the relative altitudes of crest and pass remain approximately the same as in the Western Kuen-lun, it is evident how greatly the general elevation of the twin border ridge decreases towards the east.
Its surface slopes from altitudes of io, ioo to 10,600 ft.
This part of the range is crossed by the pass of Chopur-alik at an altitude of 16,160 ft., but farther east the passes lie at altitudes of 13,380 to 10,520 ft.
In the Kalta-alaghan, which is the culminating range of this part of the Kuen-lun, and is overtopped by towering, snow-clad peaks, the passes climb to considerably higher altitudes, namely, 14,560, 1 4,47 0, 1 4,43 0 and 14,190 ft., while the pass of Avraz-davan ascends to 15,700 ft.
The passes across the first range (north) lie at altitudes of 15,675, 16,420, 17,320 and 18,300 ft.; across the second at 16,830, 17,020, 17,070 and 17,220 ft.; across the third at 16,800, 16,660, 17,065, 17,830 and 17,880 ft.; and across the fourth at 16,540, 16,765, 16,780, 18,10o and 18,110 ft.
Their constituent ranges are folded and squeezed by lateral compression into a breadth of some 150-200 m., their summits being forced up to correspondingly higher altitudes, in the E.
But although the crests of its component ranges reach altitudes of 21,500 to 22,000 ft., they are not as a rule overtopped by individual peaks of commanding and towering elevation, as the Himalayas are, but run on the whole tolerably uniform and relatively at little greater altitude than the lofty valleys which separate them one from another.
From the East Turkestan lowlands on the north the ascent is very steep, and the passes across both sets of ranges lie at great altitudes; for example, the pass of Sanju-davan in the lower range is 16,325 ft.
Littledale'sChokur Pass (9530 ft.) and others at altitudes ranging from 8600 to 1 In " Orographie des Kwen-lun," in Zeitschrift der Gesellschaft fur Erdkunde zu Berlin (1891).
A remarkable feature of the belt is the longitudinal chain of broad valleys - the Great Appalachian Valley - which, in the southerly sections divides the mountain system into two subequal portions, but in the northernmost lies west of all the ranges possessing typical Appalachian features, and separates them from the Adirondack group. The mountain system has no axis of dominating altitudes, but in every portion the summits rise to rather uniform heights, and, especially in the central section, the various ridges and intermontane valleys have the same trend as the system itself.
The Blue Ridge, rising in southern Pennsylvania and there known as South Mountain, attains in that state elevations of about 2000 ft.; southward to the Potomac its altitudes diminish, but 30 m.
