The summit is marked with a cairn, and is next to a radio transmitter and its building.

[1] Black Mixen is the only Nuttall to have a communications mast (a radio transmitter) on its summit.

[2] To the east is Bache Hill, to the south are the Black Mountains, to the west is the Great Rhos plateau.

The summit cairn is probably of Bronze Age date, with most peaks in the area showing similar barrowss.
