Stationary time capsules have been termed "messages in a bottle", such as a 1935 message in a lemonade bottle correctly portending difficult times, which was found in 2016 by masons restoring damaged Portland stone at Southampton Guildhall. A geologist left a bottled message in 1959 in a cairn on isolated Ward Hunt Island (Canada, 83°N latitude), allowing its finders in 2013 to determine that a nearby glacier had retreated over 200 feet in the intervening 54 years. More durable examples of time capsules are the Westinghouse Time Capsules of the 1939 and 1964 New York World's Fairs, intended to be opened 5,000 years after their creation.
