Big nit': I'm not the only one who has observed the rise of the buildings of the Mauna Kea Astronomy Education Center, and the question being asked is, "How is it that the buildings represent pyroclastic cones such as those of the Pacific Rim if our astronomic facilities are established on a shield volcano, one among three?" Since switching to a dome-architecture seems out of the question at this time, perhaps we should minimize our embarrassment by referring to them as cinder cones.
