to reach and explore the supposed land mass. On 21 April, the members of the expedition did, in fact, see what appeared to be a huge island on the north-western horizon. As MacMillan later said, "Hills, valleys, snow-capped peaks extending through at least one hundred and twenty degrees of the horizon". Piugaattoq, a member of the expedition and an Inuit hunter with 20 years of experience of the area, explained that it was just an illusion. He called it poo-jok, which means 'mist'. However, MacMillan insisted that they press on, even though it was late in the season and the sea ice was breaking up. For five days they went on, following the mirage. Finally, on 27 April, after they had covered some of dangerous sea ice, MacMillan was forced to admit that Piugaattoq was right—the land that they had sighted was in fact a mirage (probably a Fata Morgana). Later, MacMillan wrote: The expedition collected interesting samples, but is still considered to be a failure and a very expensive mistake. The final cost was $100,000 (equivalent to $ in ). Hy Brasil Hy Brasil is an island that was said to appear once every few years off the coast of Co. Kerry, Ireland. Hy Brasil has been drawn on ancient maps as a perfectly circular island with a river running directly through it. Lake Ontario Lake Ontario is said to be famous for mirages, with opposite shorelines becoming clearly visible during the events. In July 1866, mirages of boats and islands were seen from Kingston, Ontario. Here the described mirages of vessels "could only be seen with the aid of a telescope". It is often the case when observing a Fata Morgana that one needs to use a telescope or binoculars to really make out the mirage. The "cloud" that the article mentions a few times probably refers to a duct. On 25 August 1894, Scientific American described a "remarkable mirage" seen by the citizens of Buffalo, New York. This description might refer to looming owing to inversion rather than to an actual mirage. McMurdo Sound and Antarctica From McMurdo Station in Antarctica, Fata Morganas are often seen during the Antarctic spring and summer, across McMurdo Sound. An Antarctic Fata Morgana, seen from a C-47 transport flight, was recounted: UFOs Fata Morgana mirages may continue to trick some observers and are still sometimes mistaken for otherworldly objects such as
