Roseberry Topping & Cliff Rigg Quarry

Tees Valley RIGS

Roseberry Topping is a distinctive, isolated hill that is an erosional outlier of the main escarpment of the Cleveland Hills. It is formed of Lower and Middle Jurassic sedimentary rocks. The succession of softer shales and harder sandstones has resulted in a stepped profile. We will examine this succession as well as the Tertiary Cleveland Dyke intrusion nearby and investigate how these rocks and the late Quaternary glaciation of the area controls the form of the landscape. We will also consider the palaeobotanical interest of Roseberry Topping (the reason for its SSSI status) in the wider context of the Yorkshire fossil flora and current research at nearby sites.

• Roundhay Park - A Walk Back in Time •

Guided walks around the Geology Trail in Roundhay Park are held during the year. Provisional dates are:
  • Wednesday 3th July 2019
  • Saturday 14th September 2019
Meet at the Mansion House Visitors Centre at 1.15 PM for a 1.30 PM start.

The walks are led by the geologist who created the trail and, making regular stops, take about 2.5 hours and cover a distance of around 3 km. They are suitable for people of any age - no previous knowledge is required!

The trail follows paths which can be muddy in wet weather so appropriate footwear is advised.

The walks are free and no booking is required but for further information contact Bill Fraser on 0113 2608764 or email w.fraser@btinternet.com

A booklet, 'Roundhay Park - A Walk Back in Time' (24 pages, full colour) which describes the marked geology trail in Roundhay Park is available. It is a combined effort between LGA members, who provided the idea and the content, and Friends of Roundhay Park, who provided the help on the ground. It can be found in various local outlets for £1.00 or by post. Contact Bill Fraser on 0113 2608764 or email w.fraser@btinternet.com for further details.
