Mesas and Buttes
Mesas are broad flat topped mountains with at least one steep side. Buttes are smaller flat topped mountains or hills with steep slopes on all sides.

Spires (also towers, needles, and balanced rock) are slender isolated columns of rock, that form as the erosional remnant of a butte.
