The smallest mountain?

I know the tallest mountain on the planet is Mount Everest, but how tall is the smallest mountain in the world? Does anybody know how tall the SMALLEST mountains is?

..if you measure from base to top rather than from sea level to top, Mauna Kea is actually the tallest. The smallest is the fire ant mound in my back yard.

The Sutter Buttes (also known as the Marysville Buttes or Histum Yani (Maidu) is the smallest mountain range in the world. Sutter Buttes is located in the northern part of California Central Valley, just outside of Marysville, California.

Although, in relative terms, the smallest 'mountain' would have to be in the Maldives, where the highest point is 2.3 meters above sea level...
