Having accomplished the object of our visit, at this place, no time was lost in pushing our way into the basin of Lake Superior. The distance to it is computed to be fifteen miles above the Sault. It was nine o'clock of the morning following the day of the treaty, when the men began to take the canoes up the rapids, and transport the provisions and baggage. This occupied nearly the whole of the day. Taking leave of Lieutenant Pierce, who returned with his command, from this point and our hospitable hostess, we proceeded to the head of the portage, long before the canoes and stores all arrived. To while away the time, while the men were thus employed, we tried our skill at rifle shooting. It was six o'clock in the evening before the work of transportation was finished, and the canoes loaded, when we embarked. The view from the head of the portage is imposing. The river spreads out like an arm of the sea. In the distance appear the mountains of Lake Superior.

We proceeded two leagues, and encamped at Point aux Pins, on the Canadian shore. At six o'clock the next morning we were again in our canoes, and crossed the strait, which is here several leagues wide, to the west, or Point Iroquois Cape. In this traverse we first beheld the entrance into Lake Superior. The scene is magnificent, and I could fully subscribe to the remark made by Carver, "that the entrance into Lake Superior affords one of the most pleasing prospects in the world." The morning was clear and pleasant, with a favoring breeze, but a tempest of wind and rain arose, with severe thunder, soon after we had accomplished the passage, which compelled us hastily to land on the Point Iroquois shore. This storm detained us five or six hours before the waters were sufficiently calm to embark. Among the boulders, I picked up a fine specimen of graphic granite, most perfectly characterized. About two o'clock, we entered this great inland sea. How feeble and inadequate are all geographical attempts to describe this vast body of water, with its imposing headlands, shores, and islands. The St. Mary's River passes out between two prominent capes, called Gros Cape and Point Iroquois. The former rises up in elevated barren peaks of sienite and hornblende rock; the latter consists of nearly equally elevated masses of horizontal red sandstone, covered with a dense forest. The line of separation is, perhaps, three leagues, forming a geological gap, through which, at ancient periods, the drift and boulder strata has been forced, with an amazing power. For we find these boulders, of the disrupted sienites, hornblende, trap, and sandstone rocks of these northern latitudes heaped in profusion along the entire shores of the river, and cast out, far and wide, into the basin of Lake Huron.

There is a little island, called Isle des Iroquois, just off the foot of the American cape, which is a noted stopping-place for boat and canoe voyagers. On passing this spot, the lake spreads out like a sea. Towards the north, can be seen on the horizon the blue peaks of distant mountains. Southerly, the Point Iroquois formation of sandstone appears skirting the shore, at several miles distance. At the computed distance of fifteen miles, we passed the mouth of the Taquimenon River. It was already evening when we came here, but we were far out from shore, and the guides thought best to keep on their course a league farther, which brought us, at 11 o'clock at night, into the mouth of the Onzig, or Shelldrake River. At this spot, we found an encampment of Chippewa Indians, who were friendly, and quite profuse in their salutation of bosho. At the moment we were ready to embark, the next morning, a brigade of traders' boats, on the route to Michilimackinac, was descried, coming in to the same point. This interview detained us till 8 o'clock. Within a league, we met eighteen or twenty Chippewa canoes on their journey towards the same point; and at the computed distance of three leagues from the Onzig, we reached, and turned the bleak shores of White-Fish Point, called Namikong [41] by the Indians. Thus far, we had been imbayed in an arm of the lake which embraces Parisian Island, another link of the sandstone formation; but here the lake, stretching westwardly, displays itself in all its magnificence. On the left, spreads a long line of sandy coast; on the right, an illimitable expanse of water, which was bounded only by the horizon. Beyond these features, there is not a prominent object to catch the eye. The magnificence which first pleases, at last tires. The change of course brought the wind ahead, and we were soon compelled to land on these bleak sandy wastes. While thus detained, an express canoe from St. Mary's reached us with letters. A couple of hours were employed in dispatching this canoe on its return; meantime the wind lulled, and we went on ten miles and encamped on the sands.

The next morning, we were again in motion at five o'clock. Twelve miles coasting along this unvaried shore, brought us to the mouth of a stream called Neezhoda, Seepe, [42] or Twin River, which is imprecisely called Two-Hearted River by the traders. The peculiarity of this stream consists in the union of two separate rivers, near the point of its outlet. Seven leagues beyond this spot brought us to the inlet called Grande Marais. Immediately west of this begins an elevated naked coast of sand-dunes, called Gitche Nägow, [43] or La Grande Sables. To comprehend the geology of this coast, it is necessary to state that it consists of several heavy strata of the drift era, reaching a height of two or three hundred feet, with a precipitous front on the lake. The sands driven up by the lake are blown over these heights, forming a heavy deposit. It is this sandy deposit, falling down the face of the precipice, that appears to convert the whole formation into dunes, whereon the sandy coating rests, like a veil, over the pebble and clay-drift. Their desert and Sahara-like appearance is quite impressive to the travellers who visit these coasts in boats or canoes. The number of rapacious birds which are observed about these heights, adds to the interest of the prospect. Dr. Wolcott, and some other members of the party who ascended the formation, reported a small lake on this elevation. The sands were observed, in some places, to be deposited over its vegetation so as to arrest its growth. The largest trees were often half buried and destroyed. Not less than nine miles of the coast, agreeably to voyageur estimates, are thus characterized by dunes.

I found the sandstone formation of Cape Iroquois to reappear at the western termination of these heights on the open shores of the lake, where I noticed imbedded nodules of granular gypsum. At this point, known to our men as La Pointe des Grandes Sables, we pitched our tents, at nightfall, under a very threatening state of the atmosphere. The winds soon blew furiously, followed by a heavy rain-storm—and sharp thunder and lightning ensued. Our line of tents stood on a gently rising beach, within fifty yards of the margin of the lake, where they were prostrated during the night by the violence of the waves. The rain still continued at early daylight, the waves dashing in long swells upon the shore. At sunrise the tempest abated, and by eight o'clock the atmosphere assumed a calm and delightful aspect. It was eleven o'clock, however, before the waves sufficiently subsided to permit embarkation. Indeed, a perfect calm now ensued. This calm proved very favorable—as we discovered on proceeding three leagues—to our passing the elevated coast of precipitous rock, called Ishpäbecä, [44] and Pictured Rocks. This coast, which extends twelve miles, consists of a gray sandstone, forming a series of perpendicular façades, which have been fretted, by the action of the waves, into the rude architecture of pillared masses, and open, cavernous arches. These caverns present their dark mouths to observation as the voyager passes. At one spot a small stream throws itself from the cliffs into the lake at one leap. In some instances the cliffs assume a castellated appearance. At the spot called the Doric Rock, near the commencement of these picturesque precipices, a vast entablature rests on two immense rude pillars of the water-worn mass. At a point called Le Portail, the vast wall of rock had been so completely excavated and undermined by the lake, that a series of heavy strata of rock rested solely on a single pillar standing in the lake. The day was fine as we passed these geological ruins, and we sat silently gazing on the changing panorama. At one or two points there are small streams which break the line of rock into quadrangles. A species of dark red clay overlies this formation, which has been carried by the rains over the face of the cliffs, where, uniting with the atmospheric sand and dust, it gives the whole line a pictorial appearance. We almost held our breath in passing the coast; and when, at night, we compared our observations around the camp-fire, there was no one who could recall such a scene of simple novelty and grandeur in any other part of the world; and all agreed that, if a storm should have arisen while we were passing, inevitable destruction must have been our lot. We came to Grand Island at a seasonable hour in the evening, and encamped on the margin of its deep and land-locked harbor. Our camp was soon filled with Chippewas from a neighboring village. They honored us in the evening by a dance. Among these dancers, we were impressed with the bearing of a young and graceful warrior, who was the survivor of a self-devoted war-party of thirteen men, who, having marched against their ancient enemies the Sioux, found themselves surrounded in the plain by superior numbers, and determined to sell their lives at the dearest rate. To this end, they dug holes in the earth, each of which thus becoming a fortification for its inmate, who dared their adversaries till overpowered by numbers. One person was selected to return with the news of this heroic sacrifice; this person had but recently returned, and it was from his lips that we heard the tragic story.

My mineralogical searches along the shores this day rewarded me with several water-worn fragments of agate, carnelian, zeolite, and prase, which gave me the first intimation of our approach to the trap and amygdaloidal strata, known to be so abundant in their mineral affluence in this quarter.

We left Grand Island the next morning at six o'clock, and passing through a group of sandstone islands, some of which had had their horizontality disturbed, we came to the mouth of Laughing-fish River, where a curious flux and reflux of water is maintained. From this place, a line of sandstone coast was passed, northwardly, till reaching its terminus on the bay of Chocolate River. This is a large and deep bay, which it would have required a day's travel to circumnavigate. To avoid this, the men held their way directly across it, steering N. 70° W., which, at the end of three leagues, brought us to Granite Point. Here we first struck the old crystalline rocks or primitive formation. This formation stretches from the north shores of the Gitche Sebeeng, [45] or Chocolate River, to Huron Bay, and gives the traveller a view of rough conical peaks. These characterize the coast for a couple of days' travel. They are noted for immense bodies of iron ore, which is chiefly in the condition of iron glance. [46] At Presque Isle, it assumes the form of a chromate of iron in connection with serpentine rock. We encamped on level ground on a sandstone formation, in the rear of Granite Point, and had an opportunity of observing the remarkable manner in which the horizontal sandstone rests upon and against the granitical, or, more truly, sienitic eminences. These sandstone strata lap on the shoulders of the primitive or crystalline rocks, preserving their horizontal aspect, and forming distinct cliffs along parts of the coast. This sandstone appears, from its texture and position, to be the "old red sandstone" of geologists.

The next morning (23d) we quitted our encampment at an early hour, in a haze, and urged our way, with some fluctuations of weather, an estimated distance of eleven leagues. This brought us, at four o'clock in the afternoon, to Huron River. Sitting in the canoe, in a confined position, makes one glad at every opportunity to stretch his limbs, and we embraced the occasion to bathe in the Huron. The shore consists of a sandy plain, where my attention was called to the Kinnikenik, a plant much used by the Indians for smoking. It is the uva ursi. I had seen it once before, on the expedition, at Point aux Barques.

We inspected here, with much attention, an Indian grave, as well from the care with which it was made, as the hieroglyphics cut on the head-posts. The grave was neatly covered with bark, bent over poles, and made roof-shaped. A pine stake was placed at the head. Between this and the head of the grave, there was placed a smooth tablet of cedar wood, with hieroglyphics. Mr. Riley, our interpreter, explained these. The figure of a bear denoted the chief or clan. This is the device called a Totem. Seven red strokes denoted his scalp honors in Indian heraldry, or that he had been seven times in battle. Other marks were not understood or interpreted. A paling of saplings inclosed the space.

On the following morning, our camp was astir at the customary early hour, when we proceeded to Point aux Beignes, a distance of six miles. Attaining this point, we entered Keweena Bay, coasting up its shores for an estimated distance of three leagues. We were then opposite the mouth of Portage River, but separated from it a distance of twelve miles. I was seated in Lieutenant Mackay's canoe. The whole squadron of five canoes unhesitatingly put out. The wind was adverse; before much progress had been made in crossing, three of our flotilla, after struggling against the billows, put back; but we followed the headmost one, which bore the Governor's flag, and, seizing hold of the paddles to relieve the men, we succeeded in gaining the river. The other canoes came up the next morning, at seven o'clock, when we all proceeded to cross the Portage Lake, and up an inlet, which soon exhibited a rank growth of aquatic plants, and terminated, after following a very narrow channel, in a quagmire. We had, in fact, reached the commencement of the Keweena Portage.

Before quitting this spot, it may be well to say, that the geology of the country had again changed. Portage Lake lies, in fact, in the direction of the great copper-bearing trap dyke. This dyke, estimating from the end of the peninsula, extends nearly southwest and northeast, probably seventy miles, with a breadth of ten miles. It is overlaid by rubblestone and amygdaloid, which latter, by disintegration, yields the agates, carnelians, and other silicious, and some sparry crystalline minerals, for which the central shores of Lake Superior are remarkable. Nearly every part of this broad and extensive dyke which has been examined, yields veins, and masses of native copper, or copper ores.

The word was, when we had pushed our canoes into the quagmire, that each of the gentlemen of the party was to carry his own personal baggage across the portage. This was an awkward business for most of us. The distance was but two thousand yards, but little over a mile, across elevated open grounds. I strapped my trunk to my shoulders, and walked myself out of breath in getting clear of the brushy part of the way, till reaching the end of the first pause, or resting-place. Here I met the Governor (Cass), who facetiously said: "You see I am carrying two pieces," alluding to his canoe slippers, which he held in his hands. "A piece," in the trade, is the back load of the engagee.

On reaching the termination of the second "pause," or rest, we found ourselves on a very elevated part of the shore of Lake Superior. The view was limitless, the horizon only bounding the prospect. The waves rolled in long and furious swells from the west. To embark was impossible, if we had had our baggage all brought up, which was not the case. The day was quite spent before the transportation was completed. This delay gave us an opportunity to ramble about, and examine the shore. In a boulder of serpentine rock, I found an imbedded mass of native copper, of two pounds' weight. On breaking the stone, it proved to be bound together by thin filaments of this metal. Small water-worn fragments of chalcedony, agate, carnelian, and other species of the quartz family were found strewn along the beach, together with fragments of zeolite. Masses of the two former minerals were also found imbedded in amygdaloid and trap-rock, thus denoting the parent beds of rock. In the zeal which these little discoveries excited on the subject of mineralogy, the Chippewa, Ottowa, and Shawnee Indians attached to the expedition participated, and as soon as they were made acquainted with the objects sought, they became successful explorers. They had noticed my devotion to the topic, from the time of our passing the Islands of Shawangunk, Michilimackinac, and Flat-rock Point, in the basin of Lake Huron, where organic forms were chiselled from the rock; and bestowed on me the name of Paguäbëkiegä. [47]

It turned out the next morning, that the whole of the baggage and provisions had not been brought up, nor any of the canoes. This work was early commenced by the men. About half the day was employed in the necessary toil. When it was concluded, the wind on the lake had become too high, blowing in an adverse direction, to permit embarkation. Nothing remained but to submit to the increased delay, during which we made ourselves as familiar with the neighboring parts of the lake shore as possible. During the time the expedition remained encamped at the portage, I made a short excursion up the peninsula northeastwardly, accompanied by Captain Douglass, Mr. Trowbridge, and some other persons. The results of this trip are sufficiently comprehended in what has already been stated respecting the geology and mineralogy of this prominent peninsula.

On the following morning (27th) the wind proved fair, and the day was one of the finest we had yet encountered on this fretful inland sea. We embarked at half-past four A. M., every heart feeling rejoiced to speed on our course. The prominent headlands, west of this point, are capped, as those on its south-eastern border, with red sandstone. The wind proved full and adequate to bear us on, without endangering our safety, which enabled the steersmen to hold out boldly, from point to point. We had not proceeded far beyond the cliffs west of the portage, when the dim blue outlines of the Okaug or Porcupine Mountains [48] burst on our view. [49] Their prominent outline seemed to stretch on the line of the horizon directly across our track. The atmosphere was quite transparent, and they must have been seen at the distance of sixty miles. Captain Douglass thought, from the curve of the earth, that they could not be less than eighteen hundred feet in height. We successively passed the entrance of Little Salmon-Trout, Graverod, Misery, and Firesteel Rivers, at the latter of which a landing was made; when we again resumed our course, and entered the Ontonagon River, at half-past three in the afternoon. A large body of water enters the lake at the spot, but its mouth is filled up very much by sands. One of those curious refluxes is seen here, of which a prior instance has been noticed, in which its waters, having been impeded and dammed up by gales of wind, react, at their cessation, with unusual force. The name of the River Ontonagon [50] is, indeed, due to these refluxes, the prized dish of an Indian female having, agreeably to tradition, been carried out of the river into the lake.

Captain Douglass made observations for the latitude of the place, and determined it to be in north latitude 46° 52´ 2´´. The stationary distances of the route are given in the subjoined list, in which it may be observed that they are probably exaggerated about one-third by the voyagers and northwest traders, who always pride themselves on going great distances; but they denote very well, in all cases, the relative distances.
