… a walk back in time.
Guided walks, led by the geologist, Bill Fraser, who created the trail, will take place on the following dates in 2015;
Thursday 12th March, Saturday 9th May, Thursday 9th July, and Saturday 12th September.
Walks start at the Roundhay Park Mansion, by the cafe entrance, at 1.30 pm. Why not join in – no previous knowledge of geology is assumed. Allow 2 hours and please note paths may be muddy so sensible footwear is advisable.
Trail Guide leaflets, with photographs and descriptions of each site as well as basic background geology can be ordered by adding to your cart. They are also on sale at City Stationers Oakwood price 50p or may be purchased from Bill Fraser at the start of the walk. Further details from Bill Fraser firstname.lastname@example.org

a V shaped valley cut by glacial melt water, reveals shales and sandstones laid down some 300 million years ago when this part of the earths crust was close to the equator. Shales are formed from fine mud particles deposited as horizontal layers in quiet water conditions.
However, at one site a fold in the shales is clear evidence of later lateral compressional forces.
The shale beds in some sites contain both fresh water and marine fossils so there were also periods of sea incursion.
At higher levels shales give way to sandstones and at the highest level in Scout’s Quarry we find coarse millstone grit which contains quite large quartz pebbles. Such deposits are only transported by very fast flowing rivers. The bedding planes define the direction of flow, the sediments being derived from the erosion of mountain range to the north.
