THE COPPER REGION.

La Pointe, Lake Superior

July 28, 1845.

Map of the Mineral Lands Upon Lake Superior Ceded to the United States by the Treaty of 1842 With the Chippeway Indians.
~ Wisconsin Historical Society

In my last brief letter from this place, I had not time to notice many things which I desired to describe. I have now examined the whole coast of the southern shore of Lake Superior, extending from the Sault Ste. Marie to La Pointe, including a visit to the Anse, and the doubling of Keweena point. During the trip, as stated previously, we had camped out twenty-one nights. I examined the mines worked by the Pittsburg company at Copper harbor, and those worked by the Boston company at Eagle river, as well as picked up all the information I could about other portions of the mineral district, both off and on shore. The object I had in view when visiting it, was to find out, as near as I could, the naked facts in relation to it. The distance of the lake-shore traversed by my part to La Pointe was about five hundred miles – consuming near four weeks’ time to traverse it. I have still before me a journey of three or four hundred miles before I reach the Mississippi river, by the way of the Brulé and St. Croix rivers. I know the public mind has been recently much excited in relation to the mineral region of country of Lake Superior, and that a great many stories are in circulation about it. I know, also, that what is said and published about it, will be read with more or less interest, especially by parties who have embarked in any of the speculations which have been got up about it. It is due to truth and candor, however, for me to declare it as my opinion, that the whole country has been overrated. That copper is found scattered over the country equal in extent to the trap-rock hills and conglomerate ledges, either in its native state, or in the form of a black oxide, as a green silicate, and, perhaps, in some other forms, cannot be denied;- but the difficulty, so far, seems to be that the copper ores are too much diffused, and that no veins such as geologist would term permanent have yet positively been discovered.

The richest copper ore yet found is that raised from a vein of black oxide, at Copper harbor, worked by the Pittsburg company, which yields about seventy per cent. of pure copper. But this conglomerate cementation of trap-rock, flint, pebbles, &c., and sand, brought together in a fused black mass, (as is supposed, by the overflowings of the trap, of which the hills are composed near this place,) is exceedingly hard and difficult to blast. An opinion seems to prevail among many respectable geologist, that metallic veins found in conglomerate are never thought to be very permanent. Doctor Pettit, however, informed me that he had traced the vein for near a mile through the conglomerate, and into the hill of trap, across a small lake in the rear of Fort Wilkins. The direction of the vein is from northwest to southeast through the conglomerate, while the course of the lake-shore and hills at this place varies little from north and south. Should the doctor succeed in opening a permanent vein in the hill of trap opposite, of which he is sanguine, it is probable this mine will turn out to be exceedingly valuable. As to these matters, however, time alone, with further explorations, must determine. The doctor assured me that he was at present paying his way, in merely sinking shafts over the vein preparatory to mining operations; which he considered a circumstance favorable to the mine, as this is not of common occurrence.

The mines at Copper harbor and Eagle river are the only two as yet sufficiently broached to enable one to form any tolerably accurate opinion as to their value or prospects.

Other companies are about commencing operations, or talk of doing so – such as a New York, or rather Albany company, calling themselves “The New York and Lake Superior Mining Company,” under the direction of Mr. Larned, of Albany, in whose service Dr. Euhts has been employed as geologist. They have made locations at various points – at Dead river, Agate harbor, and at Montreal river. I believe they have commenced mining to some extent at Agate harbor.

One or two other Boston companies, besides that operating at Eagle river, have been formed with the design of operating at other points. Mr. Bernard, formerly of St. Louis, is at the head of one of them. Besides these, there is a kind of Detroit company, organized, it is said, for operating on the Ontonagon river. It has its head, I believe, in Detroit, and its tail almost everywhere. I have not heard of their success in digging, thus far; though they say they have found some valuable mines. Time must determine that. I wish it may be so.

From Copper harbor, I paid a visit to Eagle river – a small stream inaccessible to any craft larger than a moderate-sized Mackinac boat. There is only the open lake for a roadstead off its mouth, and no harbor nearer than Eagle harbor, some few miles to the east of it. In passing west from Copper harbor along the northern shore of Keweena point, the coast, almost from the extremity of Keweena point, to near Eagle river, is an iron-bound coast, presenting huge, longitudinal, black, irregular-shaped masses of trap-conglomerate, often rising up ten or fifteen feet high above water, at some distance from the main shore, leaving small sounds behind them, with bays, to which there are entrances through broken continuities of the advanced breakwater-like ledges. Copper harbor is thus formed by Porter’s island, on which the agency has been so injudiciously placed, and which is nothing but a conglomerate island of this character; with its sides next the lake raised by Nature, so as to afford a barrier against the waves that beat against it from without. The surface of the island over the conglomerate is made up of a mass of pebbles and fragmentary rock, mixed with a small portion of earth, wholly or quite incapable of cultivation. Fort Wilkins is located about two miles from the agency, on the main land, between which and the fort communication in winter is difficult, if not impossible. Of the inexcusable blunder made in putting this garrison on its present badly-selected site, I shall have occasion to speak hereafter.

~ National Park Service

In travelling up the coast from Sault Ste. Marie, the first 50 or 100 miles, the shore of Lake Superior exhibits, for much of the distance, a white sandy beach, with a growth of pines, silver fir, birch, &c., in the rear. This beach is strewed in places with much whitened and abraded drift-wood, thrown high on the banks by heavy waves in storms, and the action of ice in winter. This drift-wood is met with, at places, from one end of the lake to the other, which we found very convenient for firewood at our encampments. The sand on the southern shore terminates, in a measure, at Grand Sables, which are immense naked pure sand-hills, rising in an almost perpendicular form next to the lake, of from 200 to 300 feet high. Passing this section, we come to white sand-stone in the Pictured Rocks. Leaving these, we make the red sand-stone promontories and shore, at various points from this section, to the extreme end of the lake. It never afterwards wholly disappears. Between promontories of red stone are headlands, &c., standing out often in long, high irregular cliffs, with traverses of from 6, 7, to 8 miles from one to the other, while a kind of rounded bay stretches away inland, having often a sandy beach at its base, with pines growing in the forest in the rear. Into these bays, small rivers, nearly or quite shut in summer with sand, enter the lake.

The first trap-rock we met with, was near Dead river, and at some few points west of it. We then saw no more of it immediately on the coast, till we made the southern shore of Keweena point. All around the coast by the Anse, around Keweena bay, we found nothing but alternations of sand beaches and sand-stone cliffs and points. The inland, distant, and high hills about Huron river, no doubt, are mainly composed of trap-rock.

Going west from Eagle river, we soon after lost both conglomerate and trap-rock, and found, in their stead, our old companions – red sand-stone shores, cliffs, and promontories, alternating with sandy or gravelly beaches.

The trap-rock east and west of the Portage river rises with, and follows, the range of high hills running, at most points irregularly, from northeast to southwest, parallel with the lake shore. It is said to appear in the Porcupine mountain, which runs parallel with Iron river, and at right angles to the lake shore. This mountain is so named by the Indians, who conceived its principal ridge bore a likeness to a porcupine; but, to my fancy, it bears a better resemblance to a huge hog, with its snout stuck down at the lake-shore, and its back and tail running into the interior. This river and mountain are found about twenty miles west of the Ontonagon river, which is said to be the largest stream that empties into the lake. The site for a farm, or the location of an agency, at its mouth, is very beautiful, and admirably suited for either purpose. The soil is good; the river safe for the entrance and secure anchorage of schooners, and navigable to large barges and keel-boats for twelve miles above its mouth. The trap range, believed to be as rich in copper ores as any part of Lake Superior, crosses this river near its forks, about fifteen miles above its mouth. The government have organized a mineral agency at its mouth, and appointed Major Campbell as agent to reside at it; than whom, a better selection could not have been made.

The nearest approach the trap-rock hills make to the lake-shore, beyond the Porcupine mountain, is on the Montreal river, a short distance above the falls. Beyond Montreal river, to La Pointe, we found red-clay cliffs, based on red sand-stone, to occur. Indeed, this combination frequently occurred at various sections of the coast – beginning, first, some miles west of the Portage.

From Copper harbor to Agate harbor is called 7 miles; to Eagle river, 20 miles; to the Portage, 40 miles; to the Ontonagon, 80 miles; to La Pointe, from Copper harbor, 170 miles. From the latter place to the river Brulé is about 70 miles; up which we expect to ascend for 75 miles, make a portage of three miles to the St. Croix river, and descend that for 300 miles to the Mississippi river.

Going back to Eagle river, at the time of our visit, we found at the mine Mr. Henshaw, Mr. Williams, and Dr. Jackson of Boston, and Dr. Houghton of Michigan, who was passing from Copper harbor to meet his men at his principal camp on Portage river, which he expected to reach that night. The doctor is making a rapid and thorough survey of the country. This work he is conducting in a duplicate manner, under the authority of the United States government. It is both a topographical and geological survey. All his surveyors carry sacks, into which they put pieces of rock broken from every prominent mass they see, and carry into camp at night, for the doctor’s examination, from which he selects specimens for future use. The doctor, from possessing extraordinary strength of constitution, can undergo exposure and fatigue sufficient to break down some of the hardiest men that can be found in the West. He wears his beard as long as a Dunkard’s; has a coat and patched pants made of bed ticking; wears a flat-browned ash-colored, wool hat, and a piece of small hemp cord off a guard chain; and, with two half-breed Indians and a small dog as companions, embarks in a small bark, moving and travelling along the lake shore with great celerity.

We all sat down to dinner together, by invitation of Mr. Williams, and ate heartily of good, wholesome fare.

After dinner we paid a visit to the shafts at the mine, sunk to a considerable depth in two or three places. Only a few men were at work on one of the shafts; the others seemed to be employed on the saw-mill erecting near the mouth of the river. Others were at work in cutting timbers, &c.

They had also a crushing-mill in a state of forwardness, near the mine.

It is what has been said, and put forth about the value of this mineral deposite, which has done more to incite and feed the copper fever than all other things put together.

Professor Charles Thomas Jackson. 
~ Contributions to the History of American Geology, plate 11, opposite page 290.

Dr. Jackson was up here last year, and has this year come up again in the service of the company. Without going very far to explore the country elsewhere, he has certainly been heard to make some very extravagant declarations about this mine,- such as that he “considered it worth a million of dollars;” that some of the ore raised was “worth $2,000 or $3,000 per ton!” So extravagant have been the talk and calculations about this mine, that shares (in its brief lease) have been sold, it is said, for $500 per share! – or more, perhaps!! No doubt, many members of the company are sincere, and actually believe the mine to be immensely valuable. Mr. Williams and General Wilson, both stockholders, strike a trade between themselves. One agrees or offers to give the other $36,000 for his interest, which the other consents to take. This transaction, under some mysterious arrangement, appears in the newspapers, and is widely copied.

Without wishing to give an opinion as to the value and permanency of this mine, (in which many persons have become, probably, seriously involved,) even were I as well qualified to do so as some others, I can only state what are the views of some scientific and practical gentlemen with whom I fell in while in the country, who were from the eastern cities, and carefully examined the famous Eagle river silver and copper mine. I do not allude to Dr. Houghton; for he declines to give an opinion to any one about any part of the country.

They say this mine is a deposite mine of native silver and copper in pure trap-rock, and no vein at all; that it presents the appearance of these metals being mingled broadcast in the mass of trap-rock; that, in sinking a shaft, the constant danger is, that while a few successive blasts may bring up very rich specimens of the metals, the succeeding blast or stroke of the pick-axe may bring up nothing but plain rock. In other words, that, in all such deposite mines, including deposition of diffused particles of native meteals, there is no certainly their PERMANENT character. How far this mine will extend through the trap, or how long it will hold out, is a matter of uncertainty. Indeed, time alone will show.

It is said metallic veins are most apt to be found in a permanent form where the mountain limestone and trap come in contact.

I have no prejudice against the country, or any parties whatever. I sincerely wish the whole mineral district, and the Eagle mine in particular, were as rich as it has been represented to be. I should like to see such vast mineral wealth as it has been held forth to be, added to the resources of the country.

Unless Dr. Pettit has succeeded in fixing the vein of black oxide in the side of the mountain or hill, it is believed by good judges that no permanent vein has yet been discovered, as far as has come to their knowledge, in the country!! That much of the conglomerate and trap-rock sections of the country, however, presents strong indications and widely diffused appearances of silver and copper ores, cannot be denied; and from the great number of active persons engaged in making explorations, it is possible, if not probable, that valuable veins may be discovered in some portions of the country.

To find such out, however, if they exist, unless by accident, must be the work of time and labor – perhaps of years – as the interior is exceedingly difficult, or rather almost impossible, to examine, on account of the impenetrable nature of the woods.

During our long and tedious journey, we were favored with a good deal of fine weather. We however experienced, first and last, five or six thunderstorms, and some tolerably severe gales.

Coasting for such a great length, and camping out at night, was not without some trials and odd incidents – mixed with some considerable hardships.

On the night before we reached La Pointe, we camped on a rough pebbly beach, some six or eight miles east of Montreal river, under the lea of some high clay cliffs. We kindled our fire on what appeared to be a clear bed of rather large and rounded stones, at the mouth of a gorge in the cliffs.

Next morning early, the fire was rekindled at the same spot, although some rain had falled in the night it being still cloudy, and heavy thunder rolling, indicating an approaching storm. I had placed some potatoes in the fire to roast, while some of the voyageurs were getting other things ready for breakfast; but before we could get anything done, the rain down upon us in torrents. We soon discovered that we had kindled our fire in the bed of a wet weather creek. The water rapidly rose, put out the fire, and washed away my potatoes.

We had then to kindle a new fire at a higher place, which was commenced at the end of a small crooked log. One of the voyageurs had set the frying-pan on the fire with an Indian pone or cake an inch thick, and large enough to cover the bottom it. The under side had begun to bake; another hand had mixed the coffee, and set the coffee-pot on to boil; while a third had been nursing a pot boiling with pork and potatoes, which, as we were detained by rain, the voyageurs thought best to prepare for two meals. One of the part, unfortunately, not observing the connexion between the crooked pole, and the fire at the end of it, jumped with his whole weight on it, which caused it suddenly to turn. In its movement, it turned the frying-pan completely over on the sand, with its contents, which became plastered to the dirt. The coffee-pot was also trounced bottom upwards, and emptied its contents on the sand. The pot of potatoes and pork, not to be outdone, turned over directly into the fire, and very nearly extinguished it. We had, in a measure, to commence operations anew, it being nearly 10 o’clock before we could get breakfast. When near the Madelaine islands, (on the largest of which La Pointe is situated,) the following night, our pilot, amidst the darkness of the evening, got bewildered for a time, when we thought best to land and camp; which, luckily for us, was at a spot within sight of La Pointe. Many trifling incidents of this character befell us in our long journey.

At the mouth of the Montreal river, we fell in with a party of seventeen Indians, composed of old Martin and his band, on their way to La Pointe, to be present at the payment expected to take place about the 15th of August.

They had their faces gaudily painted with red and blue stripes, with the exception of one or two, who had theirs painted quite black, and were said to be in mourning on account of deceased friends. They had come from Pelican lake (or, as the French named it, Lac du Flambeau,) being near the headwaters of the Wisconsin river, and one hundred and fifty miles distant. They had with them their wives; children, dogs, and all, walked the whole way. They told our pilot, Jean Baptiste, himself three parts Indian, that they were hungry, and had no canoe with which to get on to La Pointe. We gave them some corn meal, and received some fish from them for a second supply. For the Indians, if they have anything they think you want, never offer generally to sell it to you, till they have first begged all they can; then they will produce their fish, &c., offering to trade; for which they expect an additional supply of the article you have been giving them. Baptiste distributed among them a few twists of tobacco, which seemed very acceptable. Old Martin presented Baptiste with a fine specimen of native copper which he had picked up somewhere on his way – probably on the headwaters of the Montreal river. He desired us to take one of his men with us to La Pointe, in order that he might carry a canoe back to the party, to enable them to reach La Pointe the next day, which we accordingly complied with. We dropped him, however, at his own request, on the point of land some miles south of La Pointe, where he said he had an Indian acquaintance, who hailed him from shore.

Having reached La Pointe, we were prepared to rest a few days, before commencing our voyage to the Mississippi river.

Of things hereabouts, and in general, I will discourse in my next.

In great haste I am,

Very respectfully,

Your obedient servant,

MORGAN.
