96 J. S. Diller — Our Youngest Volcano. 



largest trees near the cinder cone are not less than 200 years 

 old, so that the eruption at the cinder cone must have occurred 

 a little more than 200 years ago. 



On the whole, it would seem probable, therefore, that our 

 youngest volcano south of Alaska is not the cinder cone ten 

 miles northeast of Lassen peak as once supposed,, but is most 

 likely to prove to be mount Baker, in Washington.
