No it is not an extinct volcano. The presidential range of the NH's White Mountains were created due to intense pressure due to the shifting of continental plates millions of years ago. And then later sculpted by sheets of ice and glaciers. Though most of the White Mountains of NH consist of a non-volcanic "igneous granite," Mount Washington and the majority of the presidential range is made mostly from metamorphic rocks such as schist and gneiss and other minerals. There are however areas of a more volcanic igneous rock "not a volcano" in parts of the NH region extending all the way up through Montreal Quebec Canada". See Monterigian Hills" Which were created by crystallized or hardened magma that forced it's way up through the sedimentary rock. "A product of volcanic activity deep in the earths crust" that show themselves as singular "buttes" in areas where there shouldn't be hills of any type. Mount Pawtuckaway in Southern NH is an example of this. This is where magma didn't quite make it through the surface of the earth but cooled and formed a very resilient Igneous rock which over the course of millions of years shows itself as a singular hill or mountain while the less robust "sedimentary rock" disappears around it do to natural erosion.
