Athyrium cyclosorum, TrientaUs arctica, Ledum decumbens, 

 Betula rotundifolia, Empetrum nigrum, Vaccinium nliginosum 

 (fruiting freely), Cor?ms suecica (flowering), Vitis-idcea vitis- 

 idcea. And so, if one should take a census of the resurrected

EVENLY BEDDED STRATA OF KATMAI ASH LYING AS THEY FELL 



ON TOP OF A SNOW DRIFT. 



The character of the contact and the absence of ice indicate that the ash~was not 



hot as it fell. The blanketing of the ash prevented melting for five years. 



On Observation Mountain, only seven miles from the crater (June, 1917).
