The tourists were camping on the ice when the frozen sheet -- three times the size of New York City 's Central Park -- broke free early Tuesday , carried off by the tide . `` Ice breaking off is a very common thing at this time of year , '' Canadian air force spokesman Steven Neta said . The floe drifted two miles away from land and appeared to start to crumble , Neta said . Had it fallen apart , the three rubber rafts were more than large enough to hold the whole group . The cold also was not too harsh . Even that far north , daytime highs in June often rise well above freezing . More than 220 rescued from ice floes off Latvian coast .
