Where on Earth? - January 2010

Clues for January 2010:
1. Rising more than 200 meters above the surrounding area, this volcano is actually a pile of scoria — a bubbly and glassy volcanic rock that forms when lava ejected from a volcano cools midair.
2. The volcano was originally thought to have formed in about 1850, thanks to “eyewitness accounts” and what turned out to be faulty scientific observations and assumptions. Radiocarbon evidence from surrounding dead trees as well as paleomagnetic evidence has put the eruption in about 1650.
3. Named after one of the four types of volcanoes, this volcano is situated in a national park that also contains the three other types of volcanoes: shield, plug dome and composite.
Name this volcano and its location.

Answer: A more-than-200-meter-high pile of scoria, Cinder Cone in Lassen Volcanic National Park, Calif., derives its name from one of the four types of volcanoes. Initial estimates put the volcano’s birth at about 1850, but radiocarbon as well as paleomagnetic evidence have since shown that the volcano actually formed two centuries earlier in about 1650.
