Dating the landing was again Fisher's detective work, based on Hall's own log. Lieutenant Basil Hall was part of this first landing party upon it, probably under the command of Lieutenant Richard Israel Alleyn, Endymion'''s First Lieutenant. The landing appears to have begun most casually. To quote Hall's own book, "As we had nothing better on our hands, it was resolved to make an exploring expedition to visit this little islet. Two boats were accordingly manned for the purpose; ... the artists prepared their sketch books and the geologists their hammers, for a grand scientific field day." Whilst indicating the impromptu nature of the landing, this also signifies that science was a deliberate aim from the first. The sea on this "fine autumnal morning" was unusually smooth, but a swell of many feet made landing difficult and required a great deal of confidence when leaping ashore. Observations and measurements were made until a fog was observed. Concern over the Endymions continuing visibility caused them to begin their return. The increasing swell made embarking difficult and it took half an hour to gain the boats. By this time Endymion was lost in the fog. One of the party was landed back on the rock, in an attempt to scale it in search of a fog-free look-out. His first view was of an approaching fog bank, which in this area could last for some days. The ship was sighted though, and after another delay to retrieve their "shivering scout" they rowed off in chase. Unfortunately the ship didn't see them before the fog returned and they were forced to return yet again to Rockall. At this point planning began for a long stay on the island, despite their lack of provisions or fresh water. It was resolved to abandon the heavier of the two boats and to drag the other ashore to improvise an overnight shelter. Fortunately they were saved by the fog suddenly rising, revealing the ship once more. On finally returning to the ship, some five or six hours after the fog, it was almost dark. Although Hall wasn't alone in landing party, and unlikely to have been either its commander or the "shivering scout", he's known for having been the only person to publish a written account of it. The 1955 landing thus named the big ledge near the top, where they erected their flagpole, "Hall's Ledge" after the
