By August 24 they had made such excellent progress as to be nearly at the end of the hitherto explored channel. A southerly wind was helping them along, but about four in the afternoon it began to die away. They were then in Bessel Bay, and in order to see how the ice was ahead, Sir George Nares decided to land and climb to the top of Cape Morton, which is some 2000 feet in height. From the summit a magnificent view was obtained, of which the following description is given by Sir George Nares in his account of the expedition:—

"It was a beautiful morning, with scarcely a cloud in the sky. The cold, sharp wind which had benumbed us at the sea-level was local, for, on the summit of the cape, it was perfectly calm. Sixty miles distant in the south-west were the Victoria and Albert mountains of Grinnel Land, fronted by Hans Island showing clear of Cape Bryan, which had Hannah Island nestling at its base. Farther north was an elevated spur from the main range which, rising between Archer Fjord and Kennedy Channel, formed Daly Promontory. Fronting these mountains, and directly separated from them by an extensive valley extending to the northward from Carl Ritter Bay, was the black buttress-shaped cliff forming Cape Back, the southern extremity of the nearly straight running line of flat-topped coast hills extending twenty miles to Cape Defosse. From that point the coast line became more hilly, and, joining the Daly mountains, extended to Cape Lieber, a bluff headland, with Cape Baird, a low, flat point, jutting out beyond it. Still farther north were the lofty mountains of Grant's Land with steep cliffs about Cape Union, though seventy miles distant distinctly visible, forming the western extremity of Robeson Channel. Nearly due north a slight break in the continuity of the land showed where Robeson Channel opened into the Polar Sea. On the eastern side of the strait, at a distance of forty miles, was Cape Lupton, the notable landmark denominated Polaris Promontory; then came Polaris Bay with the low plains leading to Newman Bay. At my feet lay Cape Tyson and Cape Mary Cleverly on the north shore of Petermann Fjord, rising to an elevation of 1500 feet."

In this district, picturesque and beautiful as portrayed by the explorer's description, the Discovery wintered, while the Alert went on farther North. The spot where the Discovery was left, and which was named Discovery Bay, was a large, well-protected inlet inside an island, the outer point of which formed Cape Bellot. In the summer it was sparsely covered with loose ice, but in the winter, sea, hills, cape, and plains were all covered in the one white garb. As the two vessels entered the bay early on the morning of August 25, what at first were taken to be nine boulders were observed on the shore; but as the vessels swung to their anchors, the boulders were observed to move away. At once the cry of "musk oxen" was raised, and boats were hastily lowered, filled with sportsmen keen for the chase. The oxen, disturbed by the noise, made for the higher ground, where they were followed by the enthusiastic shooting party until every one of the nine was brought to the ground.

The following day, August 26, the ships parted company, the Alert taking with her an officer and a sledge team of men from the Discovery, with the idea of sending them back overland when winter quarters were selected, an idea which had to be abandoned by reason of the impassable nature of the country. On the last day of the month the Alert met a particularly heavy floe, the ice forming it being of the massive character which denoted that its origin was the Polar Sea. Once the grinding mass of hummocks, rising higher than the vessel's decks, threatened to catch her. There would have been no hope of escape if they had, and only by persistently ramming her way through some of the looser ice did she escape in towards the shore. Next day a strong gale sprang up from the south-west, and the Alert went along at ten miles an hour in an open channel between the land and the heavy pack which was drifting about three miles out. By midday they reached latitude 82° 24' N., and the flags were run up to the mastheads amid general rejoicing, for it was the farthest point North to which a ship had yet sailed.

With the channel showing clear ahead of them and the spanking breeze astern, expectation was high on board that they would be able to sail right up to latitude 84°, but within an hour their hopes were suddenly and thoroughly checked. On hauling to the westward they rounded a promontory and found that the land trended away to the west. The wind veered round to the north-west and drove the ice in upon the channel, which gradually became narrower until, when off Cape Sheridan, the main pack was observed to be touching the grounded ice and effectually barring all further progress. The Alert was run close up to the end of the channel, and then, when it was certain that there was no chance of getting through the barrier, she was anchored to a floe which rested aground off the cape. The next day, as the heavy ice of the pack was grinding against the stranded floe, and an opening just large enough for the vessel to get in was observed in the floe, she was warped into the basin.

She was barely inside when a solid hummock crushed against the opening, forming a great barrier between the vessel and the outer moving pack. Had it struck there a few minutes earlier the vessel would have been severely injured by the "nip," but as it was the hummock formed an admirable shelter from the pressure of the pack. This was often so severe that masses over 30,000 tons in weight were broken off and forced up the inclined shore, rising twelve and fourteen feet higher out of the water as they crunched along the ground.

On September 4 new ice formed on the water in which the ship was floating, and from observations taken from high land inshore all doubt was removed as to where they were. They had navigated to the end of Robeson Channel and were now in the Polar Sea. No land could be seen to the north; nothing but a vast wilderness of huge masses of Polar ice, most of which had evidently been frozen for years. At midnight on the same day they saw the last of the sun as it sank below the northern horizon.

Winter was now upon them, and they set to work to make their quarters as comfortable as possible. Snow came down heavily for some days, but not for a week or so was it hard enough to cut into the blocks suitable for building snow houses. When these were built, stores were removed to them and observatories fitted up for recording the various conditions of the atmosphere. On September 14 a severe gale sprang up, which caused the ice to move so much that the thin new ice in the basin was broken up and a boat's crew were drifted away on to a floe-berg 200 yards from the ship, from whence they were only rescued after great difficulty and in a half-frozen condition.

Some days subsequently, while a sledge party was on shore, one man was badly frost-bitten. He did not know it until some time after, but he had tried to thaw his frozen foot-wraps in his sleeping-bag instead of first removing them. The loss of feeling and then of use in his legs crippled him, and when he was brought on board it was seen what was wrong. This is one of the several evils men have to carefully guard against in the excessive cold. So long as they experience the stinging sensation of cold, they are free from a frost-bite; but a man may have his face bitten and not realise it until he is told that he has turned dead white. Circulation has then been arrested, and immediate steps have to be taken to bring it back, or the flesh becomes dead.

The dogs also began to suffer from a disease which sent them into fits, and which puzzled the Eskimo driver and the doctors. Some of them wandered away over the ice and others died, until only fifteen remained out of thirty, and many of those were thin and weakly. Then, as the cold increased, ice formed in the chimneys, and damp settled on the beams and walls between decks every time the cold air was admitted, so that it had to be constantly sponged up, while the officers had to spread waterproof coverings over their beds to protect themselves from it when they slept.
