Sir James Clark Ross and his expeditionary fleet sailed along the Ice Wall for a number of months ... he spent the next several years of his life navigating the southern coast vainly in search of a south sea passage to the other side.
"It was ... an obstruction of such character as to leave no doubt in my mind as to our future proceedings, for we might as well sail through the cliffs of Dover as to penetrate such a mass.
"It would be impossible to conceive a more solid-looking mass of ice; not the smallest appearance of any rent or fissure could we discover throughout its whole extent; and the intensely bright sky beyond it, too, plainly indicated the great distance to which it reached southward." —James Clark Ross
