Looking into the new tephra cone with Cone D, mantled thickly by debris, behind it. Tulik in the far distance outside the caldera. We estimated the new cone to rise about 800-900 feet from the old lake level out of the photo to the left. The crater is about 2500 feet across The bottom of the crater is filling with fine debris raining in down the very steep crater walls; on the 10th, we looked in and saw an accumulation of gray lithic blocks probably ballistics similar to what we found on the rim (all old dense lavas). The steaming was from a diffuse area on the crater floor with a few more strongly steaming jets; we could usually smell very faint H2S if flying close to the rim.
