They were protected from melting by their location in the polar latitudes and by the high altitude of the ice deposited during the Ice Age.

The altitude of the ice is an important factor since the atmosphere cools at an average of 3.6°F per 1,000 feet (6°C per 1,000 m).

Another useful technique is to identify events which are seen in other types of climate records, such as historical, tree ring and sedimentary records.

These all have independent methods of dating, and so the timing of a major climate shift or volcanic eruption can be used to synchronise the age scales.

Many cores however come from regions where the yearly snowfall accumulation is too small for the annual layers to be distinguished, and other methods of dating must be used.
