The aim of this day is to visit a series of locations in Saddleworth and Marsden that display strata from the lower Kinderscout age rocks (Shale Grit and Kinderscout Grits) to the stratigraphically-younger Marsdenian rocks in the area (Marsden Shales, Midgeley Grit). These locations allow a visitor to see how the sedimentary system evolved at this time, displaying a range of strata from distal marine, pro-delta, delta front and delta top environments.
