Abstracted geological map of approximate Icelandic glacier catchments and associated features present in 21st century. Glaciers shown are generally more than 5 km² (1.9 sq mi), noting that size varies from year to year and this is not original mapping work but rather uses several recent works but Openstreetmap mappings mainly as of 2024. Please refer to original sources for more accurate mappings. As six named glaciers disappeared during the second half of the 20th century the existence of a glacier on this mapping is no guarantee you will find ice at a given position if you visit Iceland at the time of reading an article that uses this data. It was developed from mappings initially used in articles on Öræfajökull, Esjufjöll, and Snæfell but based on Sigurðsson and Williams as the definite reference of named glaciers. This source is recommended for more details on historic names and names of smaller glaciers. The data will provide default glacial geological mapping for any article with suitable switching logic if emphasised as desired and allows mouse over functionality such as name of a feature.

The data is original, as a compromise representation, and for glacial features has been checked against at least two or three other mapping representations/abstractions:
