Today's best geology spot is High Force in the North Pennines, where the River Tees falls 21-22m over a vertical rock face into a plunge pool. High Force is formed of 2 distinct rock types: a dolerite igneous intrusion & a unit of interbedded fossiliferous limestones & mudstones

@BritGeoSurvey Did a field trip there with the OU back in the 90s. It was in flood and the noise was deafening. Amazing place
