A volcanic neck forms when magma solidifies in the vent of a volcano, after the solidification the volcano goes either dormant for an extended period of time or goes extinct. During this period of quiescence the ash around the vent erodes away as well as all the other light material leaving only the spine that was the plug in the vent. This will last the longest as it is very densely solidified magma versus a loose conglomerate of ash on the flanks of the volcano.

What are three features formed by magma?

What type of landform can be created when magma hardens in a volcanoes pipe?
Volcanic Neck The surrounding rock weathers more easily than the magma in the pipe. The resultant structure will first appear as a low flat protrusion which is slightly elevated from its surroundings. With additional weathering of the surrounding rock, the hardened magma may appear as a tower with possible basaltic columnar structure known as a volcanic plug or volcanic neck.
