Birmingham’s Erratic Boulders: Heritage of the Ice Age

BCGS has been a partner in a project with Herefordshire & Worcestershire Earth Heritage Trust, the Lapworth Museum of Geology and Birmingham Open Spaces Forum which was funded by the National Lottery Heritage Fund. We have helped to produce 8 trails of walks and/or cycle rides linking many glacial erratic boulders in south-west Birmingham and north-east Worcestershire with Trail 8 almost entirely in Dudley MBC. The project has its own website:

Wren’s Nest Nature Reserve:

Wren’s Nest Hill was declared a National Nature Reserve in 1956 (the first in the U.K. for geology). The establishment of the Reserve was in recognition of the exceptional, international importance of the site as a source of Silurian (Wenlock) age fossils.
