When Olivia is describing to Peter the wall of missing persons behind him, the "mind's eye" visual shows a wall of missing persons fliers, one of which states "LAST SEEN JUNE 12 2033". The current year is 2036 and they have been frozen in amber for 21 years since 2015, so the wall being recalled and described was from 2015 or earlier, making the 2033 date nonsensical.
On a tape Walter give a location of 49 degrees 20 minutes 2 seconds north by 79 degrees 12 minutes 32 second west is in Pennsylvania but these coordinates are in northern Quebec Canada.
When the team is watching the video tape, Walter gives the coordinates as 49° 20' 2" North 79° 12' 32" West. Olivia repeats the location as 41° 20' 2" North 79° 12' 32" West. Etta asks, "Are you sure?" Peter responds, "She's sure." Also, Walter's location would put them in Canada.
