Northumberland Wildlife Trust’s 50th anniversary Rock Festival has featured many geological gems over the course of the last year and now 50 of them have made it into a new book.

With uncertainty surrounding music festival this summer and Glastonbury cancelled for the second year running, Northumberland Wildlife Trust has launched its very own Rock Festival.

Fifty years ago, in 1971, there were two amazing launches - the first Creme Eggs rolled off the Cadbury production line and Northumberland Wildlife Trust began.
