Mauna Kea's great height and the steepness of its flanks provide a better view and a shorter hike than the adjacent Mauna Loa. By examining data from the two volcanoes, Mr. Jones and his team suggested an alternative: The chemical signature, along with this double-track volcanism as it’s called, occurred three million years ago when the plates above the hot spot shifted direction, moving north. “Mauna Kea” spelled as two words refers to any white mountain—it is a common noun (vs. the proper noun) [].
