Marvel Comics' third teaser of the day asks "Who found Captain America on ice before the Avengers," with an ensuing story promised to begin in March 2019.
Of course, in comic books Captain America's frozen body was found (and worshipped) by a group of Inuit people. The anti-hero Namor wandered in and, not knowing it was Captain America, broke open the ice in an effort to break the group's "idol." Namor didn't realize his World War 2 ally was inside the ice however, and threw him into the ocean where he is ultimately found by the Avengers.
Presumably however this will be retconned as "Marvel history is destroyed."
