PHYSICAL GEOGRAPHY OF CALIFORNIA.

Whatever appertains to California, the new El Dorado of the southwest,

is interesting to Americans and indeed to the whole civilized world.

The following brief account, therefore, of its physical geography,

compiled from authentic sources and carefully condensed, will readily

receive the attention of the inquiring mind:

"Upper California extends, upon the Pacific, from the 32d parallel of

latitude, about seven hundred miles north-westward to Oregon, from

which it is divided, nearly in the course of the 42d parallel--that is

in the latitude of Boston--by a chain of highlands called the Snowy

Mountains; the Sierra Nevada of the Spaniards. Its boundaries on the

west are not, as yet, politically determined by the Mexican government;

nor do geographers agree with regard to natural limits in that

direction. By some, it is considered as embracing only the territory

between the Pacific and the summit of the mountains which border the

western side of the continent: others extend its limits to the

Colorado; while others include in it, and others again exclude from it,

the entire regions drained by that river. The only portion occupied by

Mexicans, or of which any distinct accounts have been obtained, is that

between the great chain of mountains and the ocean; the country east of

that ridge to the Colorado appears to be an uninhabitable desert.

"Northward from the Peninsula, or Lower California, the great

western-most chain of mountains continues nearly parallel with the

Pacific coast, to the 34th degree of latitude, under which rises Mount

San Bernardin, one of the highest peaks in California, about forty

miles from the ocean. Further north the coast turns more to the west,

and the space between it and the summit line of the mountains becomes

wider, so as to exceed eighty miles in some places; the intermediate

region being traversed by lines of hills, or smaller mountains,

connected with the main range. The principal of these inferior ridges

extends from Mount San Bernardin north-westward to its termination on

the south side of the entrance of the Bay of San Franciso, near the

38th degree of latitude, where it is called the San Bruno Mountains.

Between this range and the coast run the San Barbara Mountains,

terminating on the north at the Cape of Pines, on the south-west side

of the Bay of Monterey, near the latitude 361/2 degrees. North of the

San Bruno mountains is the Bolbones ridge, bordering the Bay of San

Francisco on the east; and still further in the same direction are

other and much higher lines of highlands, stretching from the great

chain and terminating in capes on the Pacific.

"The southern part of Upper California, between the Pacific and the

great westernmost chain of mountains, is very hot and dry, except

during a short time in winter. Further north the wet season increases

in length, and about the Bay of San Francisco the rains are almost

constant from November to April, the earth being moistened during the

remainder of the year by heavy dews and fogs. Snow and ice are

sometimes seen in the winter on the shores of the bay, but never

further south, except on the mountain tops. The whole of California is,

however, subject to long droughts." Heavy rains are of rare occurrence,

and two years without any is not unusual; notwithstanding which,

vegetation does not suffer to the extent that might be inferred,

because, in the first place, many small streams descend from the

mountain ranges, supplying the means of both natural and artificial

irrigation; and, next, that the country near the coast is favored with

a diurnal land and sea breeze; and, from the comparatively low

temperature of the sea, the latter is always in summer accompanied with

fogs, in the latter part of the night, and which are dissipated by the

morning's sun, but serve to moisten the pastures and nourish a somewhat

peculiar vegetation abounding in beautiful flowers.

"Among the valleys of Upper California are many streams, some of which

discharge large quantities of water in the rainy season; but no river

is known to flow through the maritime ridge of mountains from the

interior to the Pacific, except perhaps the Sacramento, falling into

the Bay of San Francisco, though several are thus represented on the

maps. The valleys thus watered afford abundant pasturage for cattle,

with which they are covered; California, however, contains but two

tracts of country capable of supporting large numbers of inhabitants,

which are that west of Mt. San Bernardin, about the 34th degree of

latitude, and that surrounding the Bay of San Francisco, and the lower

part of the Sacramento; and even in these, irrigation would be

indispensable to insure success in agriculture."

"The provincial terms of New Mexico, and of Upper and Lower California,

have been, and are yet, rather designations of indefinite tracts than

of real defined political sections. The Pacific ocean limits on the

west, and by treaty, N. lat. 42° on the north; but inland and

southward, it is in vain to seek any definite boundary. In order,

however, to give as distinct a view as the nature of the case will

admit, let us adopt the mouth of the Colorado and Gila, or the head of

the Gulf of California, as a point on the southern boundary of Upper

California. The point assumed coincides very nearly with N. lat. 32°

and, if adopted, would give to that country a breadth of ten degrees of

latitude or in round numbers 800 statute miles from south to north. As

already, stated, the Pacific Ocean bounds this country on the west, and

lat. 42° on the north. To separate it on the east from New Mexico, we

must assume the mountain chain of Sierra Madre, or Anahuac, which, in

this region, inclines but little from north to south: whilst the

Pacific coast extends in general course north-west and south-east.

These opposite outlines contract the southern side to about 500 miles,

and open the northern side to rather above 800 miles; giving a mean

breadth of 650 miles. The area, for all general purposes, may be safely

taken at 500,000 square miles. The general slope or declination of this

great region is westward, towards the Pacific and Gulf of California."

"The climate of the western slope of North America has a warmth ten

degrees at least higher than the eastern, upon similar latitude. The

cause of this difference is the course of prevailing winds in the

temperate zones of the earth, from the western points. Thus the winds

on the western side of the continent are from the ocean, and on the

eastern from the land.

"The soil is as variable as the face of the country. On the coast range

of hills there is little to invite the agriculturist, except in some

vales of no great extent. The hills are, however, admirably adapted for

raising herds and flocks, and are at present the feeding-grounds of

numerous deer, elk, &c., to which the short, sweet grass and wild oats

that are spread over them afford a plentiful supply of food. The valley

of the Sacramento, and that of San Juan, are the most fruitful parts of

California, particularly the latter, which is capable of producing

wheat, Indian corn, rye, oats, &c., with all the fruits of the

temperate, and many of the tropical climates. It likewise offers

pasture grounds for cattle. This region comprises a level plain, from

fifteen to twenty miles in width, extending from the Bay of San

Francisco, beyond the mission of that name, north and south. This may

be termed the garden of California; but although several small streams

and lakes serve to water it, yet in dry seasons or droughts, not only

the crops but the herbage also suffers extremely, and the cattle are

deprived of food." The most extensive portion of Upper California--the

inland plain between the California and the Colorado range of

mountains--is an arid waste, destitute of the requisites for supplying

the wants of man. This plain is a waste of sand, with a few detached

mountains (some of which rise to the region of perpetual snow,) whose

positions are unknown; from these flow small streams that are soon lost

in the sand. A few Indians are scattered over the plain, the most

miserable objects in creation."

The climate is very peculiar, the thermometer on the coast ranging as

high, on the average, in winter as in summer. Indeed, summer is really

the coldest and most disagreeable part of the year, owing to the

north-west winds which frequently prevail during that season. As you

recede from the coast, however, the climate undergoes a great change

for the better. At San Juan, thirty miles from the coast, is one of the

most delightful climates in the world. The two principal rivers in

Upper California are the Sacramento and the San Joaquim. There are,

however, many smaller streams flowing through the different valleys,

which serve, during the dry season, to irrigate the land. The only

navigable stream is the Sacramento.

Beside the bays and harbors of Monterey, Santa Barbara and San Pedro,

Upper California possesses the harbor of San Francisco, within a few

miles of the Gold Mines, and one of the largest and most magnificent

harbors in the world.

The yield of wheat, small grain, and vegetables, is said to be great,

and very remarkable, but, as agriculture cannot succeed in Upper

California, but by irrigation, it has hitherto happened that it has

been principally occupied as a pastoral country--as costing less labor

to rear cattle, for which it is only necessary to provide keepers, and

have them marked. The numerous animals which are there slaughtered for

little more than their hides and tallow, do not putrify and become

offensive as they would in other climates, but, as wood is not

everywhere as abundant as their bones, the last are sometimes used to

supply the place of the former, in the construction of garden fences &c.

"The area of Upper California is about 500,000 square miles, and the

population, exclusive of Indians scattered over this extent, as follows:

Californians descended from Spain,----------------- 4000 Americans from

United States,---------------------- 360 English, Scotch, and

Irish,------------------------ 300 European

Spaniards,-------------------------------- 80 French and

Canadians,------------------------------ 80 Germans, Italians,

Portugese, and Sandwich Islanders, 90

Mexicans,------------------------------------------ 90

Total---------------------------------------------- 5000

"Upper California is, on the whole, admirably fitted for colonization.

This province presents the greatest facilities for raising cattle, for

cultivating corn, plants, and for the grape; it might contain twenty

millions of inhabitants; and its ports are a point of necessary

communication for vessels going from China and Asia to the western

coasts of North America.

"It is beyond doubt, that so soon as an intelligent and laborious

population is established there, this country will occupy an elevated

rank in the commercial scale; it would form the _entrepôt_ where the

coasts of the great ocean would send their products, and would furnish

the greatest part of their subsistence in grains to the north-west, to

Mexico, to Central America, to Ecuador, to Peru, to the north coast of

Asia, and to many groups of Polynesia--such as the Sandwich isles, the

Marquesas, and Tahiti."

"The peninsula of Lower California, extending from Cape San Lucas to

the Bay of Todos Santos, in lat. 32° N., on the Pacific, and to the

mouth of the Colorado on the Gulf side, is a pile of volcanic debris

and scoriae. Much of the surface is still heated by subterranean fires.

No craters are in action; but hot springs of water and bitumen, and

frequent earthquakes, and the scorched face of the whole region,

demonstrate it to be a mere mass upheaved from the sea, and burned to

cinders. The range of mountains that comes up through Lower California,

runs on northwardly into Upper California, at an average distance of

sixty or seventy miles from the sea, till it falls away into low hills

south of the bay of San Francisco. This, also, is a volcanic range;

though not so strongly marked to that effect in the Upper as in the

Lower Province.

"Some portions of this range are lofty. That part lying east and

southeast of El Pueblo de los Angelos, is tipped with perpetual snows.

But the greater part of it presents a base covered up to more than half

of the whole elevation with pine and cedar forests; the remaining

height being composed of bare, dark, glistening rocks, lying in

confused masses, or turreted in the manner observed on the Black Hills

in the Great Prairie Wilderness---spires, towers, and battlements,

lifted up to heaven, among which the white feathery clouds of beautiful

days rest shining in the mellow sun.

"The Snowy Mountain range is perhaps the boldest and most peculiar of

the California highlands. Its western terminus is Cape Mendocino, a

bold snow-capped headland, bending over the Pacific in 40° north

latitude. Its western terminus is in the Wind River Mountains, latitude

42° N., about seven hundred miles from the sea. Its peculiarity

consists in what may be termed its confused geological character. Near

the sea its rocks are primitive, its strata regular. A hundred miles

from the sea where the President's range crosses it, everything is

fused--burned; and at the distance of seventy miles northeastwardly

from the Bay of San Francisco, a spur comes off with a lofty peak,

which pours out immense quantities of lava, and shoots up a flame so

broad and bright as to be seen at sea, and to produce distinct shadows

at eighty miles' distance. Here is an extensive tract of this range

which has been burned, and whose strata have been torn from their

natural positions; displaying an amalgamated mass of primitive rock _ex

loco_, mingled with various descriptions of volcanic remains. From this

point eastward, it is a broken irregular chain of peaks and rifted

collateral ranges, and spurs running off northwardly and southwardly,

some of which are primitive and others volcanic.

"Another range of mountains which deserves notice in this place, is

that which bounds the valley of the San Joaquim on the east. This is a

wide and towering range. It is in fact a continuation of the

President's range, and partakes very strongly of its volcanic

character. That part of it which lies eastwardly from the Bay of San

Francisco, is very broad and lofty. One of its peaks, Mount Jackson, as

it is called, is the highest in all the President's range. Mountains of

great size are piled around it, but they appear like molehills beside

that veteran mount. Its vast peak towers over them all several thousand

feet, a glittering cone of ice.

"All over the Californias, the traveler finds evidences of volcanic

action. Far in the interior, among the deserts; in the streams; in the

heights; in the plains; everywhere, are manifestations of the fact,

that the current of subterranean fire which crossed the Pacific,

throwing up that line of islands lying on the south of the Sea of

Kamschatka, and passed down the continent, upheaving the Oregon

territory, did also bring up from the bed of the ocean the Californias.

"The peninsula, or lower California, which extends from Cape San Lucas

in N. lat. 22° 48', to the Bay of Todos Santos in lat. 32° N., is a

pile of barren, volcanic mountains, with very few streams, and still

fewer spots of ground capable of sustaining vegetation. The territory

lying north and south of the Colorado of the west, and within the

boundaries of the Californias, is a howling desolation.

"From the highlands near the mouth of the Rio Colorado, a wild and

somewhat interesting scene opens. In the east appears a line of

mountains of a dark hue, stretching down the coast of the Gulf as far

as the eye can reach. These heights are generally destitute of trees;

but timber grows in some of the ravines. The general aspect, however,

is far from pleasing. There is such a vastness of monotonous

desolation; so dry, so blistered with volcanic fires; so forbidding to

the wants of thirsting and hungering men, that one gladly turns his eye

upon the water, the _Mar de Cortez_, the Gulf of California. The

Colorado, two and a half miles in width, rushes into this Gulf with

great force, lashing as it goes the small islands lying at its mouth,

and for many leagues around the waters of the Gulf are discolored by

its turbulent flood. On the west, sweep away the mountains of Lower

California. These also are a thirsty mass of burned rocks, so dry that

vegetation finds no resting-place among them.

"That province of Lower California varies from thirty to one hundred

and fifty miles in width, a superficial extent almost equal to that of

Great Britain; and yet on account of its barrenness, never will, from

the products of the soil, maintain five hundred thousand people in a

state of comfort, ordinarily found in the civilized condition. Every

few years tornadoes sweep over the country with such violence, and

bearing with them such floods of rain, that whatever of soil has been

in any manner previously formed, is swept into the sea. So that even

those little nooks among the mountains, where the inhabitants from time

to time make their fields, and task the vexed earth for a scanty

subsistence, are liable to be laid bare by the torrents. In case the

soil chance to be lodged in some other dell, before it reach the Ocean

or the Gulf, and the people follow it to its new location, they find

perhaps no water there and cannot cultivate it. Consequently they are

often driven by dreadful want to some other point in quest of

sustenance, where they may not find it, and perish among the parched

highlands. The mean range of temperature in the whole country in the

summer season is from 60° to 74° Fahrenheit. The rains fall in the

winter months; are very severe, and of short duration. During the

remainder of the year the air is dry and clear; and the sky more

beautiful than the imagination can conceive.

"The range of mountains occupying the whole interior of this country,

vary in height from one to five thousand feet above the level of the

sea. They are almost bare of all verdure, mere brown piles of

barrenness, sprinkled here and there with a cluster of briars, small

shrubs, or dwarf trees. Among the ridges are a few spots to which the

sweeping rains have spared a little soil. These, if watered by springs

or streams, are beautiful and productive. There are also a few places

near the coast which are well adapted to tillage and pasturage.

"But the principal difficulty with this region, is one common to all

countries of volcanic, origin,--a scarcity of water. The porousness of

the rocks allows it to pass under ground to the sea. Consequently one

finds few streams and springs in Lower California. From the Cape San

Lucas to the mouth of the Colorado, six hundred miles, there are only

two streams emptying into the Gulf. One of these is called San Josef

del Cabo. It passes through the plantations of the Mission bearing the

same name, and discharges itself into the bay of San Barnabas. The

other is the Mulege, which waters the Mission of Santa Rosalia, and

enters the Gulf in latitude 27° N. These are not navigable. The streams

on the ocean coast, also, are few and small. Some of them are large

enough to propel light machinery, or irrigate considerable tracts of

land, but none of them are navigable. In the interior are several large

springs, which send out abundant currents along the rocky beds of their

upper courses; but when they reach the loose sands and porous rocks of

the lower country, they sink and enter the sea through subterranean

channels. A great misfortune it is too, that the lands which border

those portions of these streams which run above the ground, consist of

barren rocks. Where springs, however, and arable land occur together,

immense fertility is the consequence. There is some variety of climate

on the coasts, which it may be well to mention. On the Pacific shore

the temperature is rendered delightfully balmy by the sea breezes, and

the humidity which they bring along with them. Fahrenheit's thermometer

ranges on this coast, during the summer, between fifty-eight and

seventy-one degrees. In the winter months, while the rains are falling,

it sinks as low as fifty degrees above zero. On the Gulf coast there is

a still greater variation. While at the Cape, the mercury stands

between sixty and seventy degrees, near the head of the Gulf it is down

to the freezing point.

"These isolated facts, in regard to the great territory under

consideration, will give the reader as perfect an idea of the surface

and agricultural capacities of Lower California as will be here needed.
