Calf Top is a mountain in the western part of the Yorkshire Dales, England. It is located in the county of Cumbria, although Lancashire and North Yorkshire are not far away. Calf Top is a dominating profile in the view from many of the smaller hills to its west, such as Lambrigg Fell and Hutton Roof Crags.

Calf Top is separated from its neighbours, Great Coum and Aye Gill Pike by the deep trench of Barbondale, meaning that although it is lower than most of the hills in its region, it has high

Status as a mountain

The height was formerly shown on

Deweys who all agreed that the hill should retain its current status as a member of Dewey's list of hills at least 500 metres but less than 609.6 metres high.^[4]

Current OS maps show the height rounded to 610 metres.

The Ordnance Survey recalculated the height of the mountain in 2016 when the authoritative definition of the

Ordnance Datum Newlyn, was transitioned from the OSGM02 geoid model to the OSGM05 version, causing a general upwards shift of 25mm in orthometric heights.^[5] This resulted in a height of 609.606 metres, thus updating the status of Calf Top from hill to mountain.^[6]^[7]
