When magma has solidified in a volcanoes vent it is known as a volcanic plug. In some cases when there is a plug present in a stratovolcano, it can lead to very large explosive eruptions as pressure builds within the volcano.
Hardened magma in a volcano's pipe that remains when softer rock around it has worn away is called the volcanic neck.

In a volcano's pipe, magma can solidify and form a structure known as a volcanic neck or plug. Over time, erosion and weathering can wear away the surrounding rock, exposing this hardened magma. The volcanic neck is often more resistant to erosion than the surrounding material, leading to its prominent elevation once the softer rock has been removed. Examples include prominent formations like Shiprock in New Mexico.

a volcanic neck forms when magma hardens in a volcano's pipe and is later exposed.

volcanic neck
A volcanic neck is eventually exposed by erosion of the surrounding softer rock.
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.
Mount St. Helens is a stratovolcano, which means it is composed of layers of hardened lava, ash, and volcanic rock. Inside the volcano, there is a conduit or pipe that allows magma to rise to the surface during eruptions. The magma chamber is the reservoir of molten rock beneath the volcano where magma accumulates before being erupted.
