The summit, known as Garrowby Hill, lies about five miles (eight kilometres) north of Pocklington.

Topography detailed from LIDAR info, in the database of British Hills, gives the summit as 247.9 metres (813 ft) on the tumulus north of the A166 road just to the east of the 246-metre (807 ft) OS map height given for the triangulation pillar that is within the reservoir.

The British artist David Hockney painted the view from the summit in 1998.

Around 10 am on 7 February 1944[4] a Halifax MkV DK192 (OO-N) from 1663 HCU based at RAF Rufforth[5] crashed on Garrowby Hill.

[6] As well as the 7 aircrew who were on a training flight, a passing lorry driver was also killed.
