One of these places is Sarmiento Shoal that juts out into the Atlantic for miles from Cape Virgins, the Argentine headland, 135 feet high, that marks the beginning of the eastern end. It really is no more dangerous to cross, for example, than the shoals of Nantucket. The fleet came down to the shoal about noon. There is one place where there are nine fathoms of water and it has a width of only four or five miles. The task is to fix the place of crossing from bearings and then to cross it. When the exact spot was reached a fierce black cloud came up and obscured things. With it came a strong southwest wind that made things choppy. Over the narrow part of the shoal the ships headed. Once or twice, perhaps because the looks of the water or the lead may have given warning, the flagship made short turns. But in half an hour it was over and the fleet turned to the northwest, past Dungeness light, five miles below Cape Virgins, and marking the real entrance to the strait, which is now under the entire jurisdiction of Chile. From the mast of the Chilean signal station there fluttered flags which said, in the language of the international code: "Enter Chilean waters; welcome distinguished American seamen; pleasant voyage." The fleet voted the sentiment all right, even if the verbiage was somewhat unusual. There was a quick run up into the broad waters of Possession Bay, close to the entrance of the First Narrows. There are two narrows on the run to Punta Arenas and here is where the tide runs strongest in the strait. If the tide is against you it is better to anchor and wait for the turn. There is a good anchorage in the bay and about 4 o'clock of the afternoon of January 31 the mudhooks were dropped in a boiling sheet of water that in its actions resembled the lower part of Chesapeake Bay in a storm. At daylight the next morning the fleet was under way again with a favorable tide. The First Narrows are ten miles long, two wide and have water forty fathoms deep. There was no trouble in just skimming right along. Then the ships entered another big bay, Philip Bay, and after about twenty-five miles of deep water came to the Second Narrows, twelve miles long. This passage also has a swift tide, but the waterway is about three miles wide and very deep, and no one had any concern about getting through. It was as easy as rolling down hill. Then came the waters of Broad Reach, the wide sheet of water that stretches clear down to Punta Arenas. At the very beginning there is one of the two really difficult places in the strait to navigate. The reach has extensive shoals. Santa Magdalena Island, with a lighthouse on it, faces an oncoming ship and there are two channels, one to the north and the other to the south. Small vessels usually take the north passage, called Queen's Channel, but larger ones take the other, known as New Channel. There are two buoys which indicate dangerous places from tide rips and shoals.
