After breakfast, we strapped on our packs and recommenced our march, our object being to reach the shore of the lake as soon as possible. If there were any native inhabitants in this region, they would probably be found there; and we would either get them to put us across the lake in their canoes, or else we would skirt along it until we could again take a westerly course.
We soon found that we had got into a region subject to violent volcanic action, and were compelled to turn aside to avoid a wide space full of ponds, the intervals between which were covered with a crust of brimstone. I attempted to reach one of the ponds, but had not gone far when the point of my pole went through the crust, and up bubbled a quantity of black slime. On touching it, and finding it scalding hot, I shouted to my companions, who were behind, not to venture on the treacherous ground. A horror seized me, and every instant I feared that I should break through the surface. Should that take place, what a dreadful fate would be mine! I hastened back, stepping cautiously, as if moving over ice too thin to bear my weight; and very thankful I was when I once more got on hard ground.
Still further on, as we proceeded down the valley, we saw vapour rising from numerous fissures in the hill-sides. Around these vents quantities of sulphur had been deposited. But the most curious objects were basins of all sizes, nearly circular, of which there were great numbers—formed, apparently, by the lime contained in the hot springs. Some of these springs were exhausted; others, as they gushed forth from the mountain-side, were hot enough to boil potatoes. Beautiful as was the appearance of the basins, we were too eager to push forward, to examine them minutely. One was from twelve to twenty feet in diameter, and had a beautifully scalloped border. So perfect was the shading of the scallops, that it looked like a most delicate work of art rather than the production of nature. From the centre spouted up water to the height of seven or eight feet. Farther on was another boiling spring, of far greater dimensions,—a horrible-looking caldron, the water dark and muddy, and in ceaseless agitation.
“Here is a pot suitable for the witches’ caldron in Macbeth,” cried out Manley.
He was rather ahead of me, and on overtaking him I found him standing by the side of a circular basin whose diameter we calculated to be fully twenty feet. The contents consisted of what greatly resembled hasty pudding, or, as Manley said, “a huge caldron of thick mash.” The whole surface was bubbling up every instant, and giving off a thud like the noise produced by the escape of the gas below.
Curious as these sights were, we were still more astonished by the appearance of the side of the mountain, the base of which we passed. All up the slope was seen, as it were, one above another, a succession of large basins or reservoirs. The margins were beautifully scalloped and adorned with natural bead-work of exquisite beauty. In spite of our hurry, we could not resist the temptation of making our way up to them. One of the largest springs we calculated to be fully thirty feet in diameter; and so perfectly transparent was the water, that, as we looked down into it, we could see to the very bottom. Its sides were ornamented with coral-like forms of various shades, from pure white to bright cream-yellow, while the blue sky overhead gave an azure tint to the whole surface which no art could imitate. Over several parts of the rim the water was flowing down into other basins. I climbed up and looked over into one of the pools, which was literally hanging on to the one above it like a bird’s nest to a wall; while beautiful stalactites were suspended below it, caused by the water which flowed over the sides. The temperature of the water when it came out of the side of the mountain was high, but in the course of its passage from pool to pool it became gradually cooler.
“I cannot resist the temptation of taking a bath in one of these beautiful basins,” exclaimed Manley.
Selecting one, I followed his example; and the sergeant was soon sitting in a third, with his head just above the water. Nothing could be more refreshing and invigorating, and when we got out we all agreed that we felt better able to continue our journey.
We found that the clear atmosphere of this region greatly deceived us as to distances, and it was not until the following day that we arrived on the shores of the lake. It was nearly evening when, after having penetrated a thick pine forest, we at length stood on its borders. Few lake-scenes could be more beautiful than that now spread out before us. The southern shore was indented with long narrow inlets, while pine-crowned promontories stretched from the base of the hills on every side. Islands of emerald hue dotted its surface, and round the margin was a sparkling belt of yellow sand. The surface, unruffled by a breath of air, was of a bright green near the shore, shading into a dark ultramarine towards the centre. Whether there were fish, we had yet to discover; but we had no fear of starving, for the whole surface of the lake swarmed with birds—swans, gulls, pelicans, geese, herons, brants, sand-hill cranes, and many varieties of ducks. An island in view was literally white with the numbers of pelicans which had taken up their abode upon it. We had also seen many other birds during the day—eagles, hawks, ravens, ospreys, prairie-chickens, grouse, mocking-birds, and woodpeckers; while we caught sight of several kinds of deer, elk, and mountain sheep. Even buffalo had made their way into the valley. Grizzly bears and panthers, too, we had good reason to fear, abounded, and were likely to be troublesome to us.
We formed our camp on the shore of the lake, where there was fuel in abundance; and taking my gun, in the course of a quarter of an hour I shot geese and ducks enough to give us an ample supper, and breakfast next morning. Manley, who was a good angler, had, in the meantime, been fitting up a rod and line—for he had brought hooks with him; and I found, when I got back, that he and the sergeant had caught a dozen salmon-trout, between a pound and a pound and a half in weight. Their colour was of a light grey above, and a pale yellow below. The dorsal and caudal fins were dark grey, and the others mostly of a brilliant orange or bright yellow.
