On a sunny, if breezy, afternoon we were joined by expert Andrew Mathieson to explore the geology of Troopers Hill.
Unfortunately due to the work in progress on the chimney we were unable to examine its Pennant sandstone closely but we were able to look at the many natural outcrops of the sandstone and the exposed faces of the quarry as we walked down the hill.
Andrew explained how the nature of the rock changed as we moved down the hill and we saw siltstones and mudstones. At the bottom of the hill stands the second chimney and here Andrew described the different depths at which coal seams had been recorded.
Moving back up on to the hill we heard about the fireclay mining before returning to the chimney to look at the view and talk about the geological history of Bristol as a whole.
