Nab Scar is a Lake District fell of 450 m in Westmorland and Furness. It barely stands apart: the summit is only 2 m above the col joining it to higher ground.
Only two Wainwrights have less drop. It sits below Heron Pike (Rydal), only 1.1 km to the north and 162 m higher. Its key col leads to Fairfield, not to its nearest higher summit, Heron Pike (Rydal). It is 201 m below the average height of the 103 register hills in Westmorland and Furness. The database describes the top as a large cairn beyond wall.
