step - steptoe
Yes, that's a real word...

(other than the British TV show 'Steptoe & Son', which 'Sandford & Son' was based on... lol)
steptoe, also called Dagala, a hill or mountain that projects like an island above a surrounding lava field. This landform, a type of kipuka, is named after Steptoe Butte, a quartzite protrusion above the Columbia Plateau lava flows near Colfax, Washington, U.S.
