Welcome to the Ice Age Coast
The Yorkshire Type Erratics Collection
at the University of Hull
Geologists have been studying the erratics of Holderness for many years. The Hull Geological Society published its first Boulder Survey in 1893. There has never been a reference collection of the erratics that can been used by scientists for comparison with their own research. This project aims to start a collection at the Geology Department at the University of Hull, which can fulfill that role.
Geologists can visit the collection (by appointment), use the catalogue and request to view images of the specimens.
There are some limitations to this work, though. Of necessity the specimens in the collection cannot be too large, so rocks which exhibit large features may not be able to represented fully. There is a natural tendency for the geologists to collect the rocks they recognise. It is therefore not a randomized sample of rocks and will be enriched in the less common rock types.
The groups of rocks in the collection are -
Specimens from the Basement Till
Specimens from the Skipsea Till
Specimens from the Withernsea Till
Specimens collected off the beaches
Specimens which are not glacial erratics (man made, building stones or introduced by man for sea defenses)
Specimens collected from the source areas of the erratics
The Lewis Penny Collection at the University of Hull, also contains erratics and other Quaternary specimens collected by Lewis Penny and his research students.
The specimens were photographed dry against a pale blue card background in dull daylight.

I wish to thank Anne Horne and Susan Lee for help with the fieldwork.
