July 18 - The last two days provided more new information about the Holocene history of Makushin. A package of previously unrecognized post-glacial lava flows was found at the head of the valley ending at Bishop Point. Two very young vents - one of which fed a substantial lava flow, were found high above Pt. A lateral blast and debris avalanche package of Holocene age was found at Koriga Point. The antenna mast at the receive site was erected.
Seismologists continue with in-town wiring of seismic components.
Field installation is slowed, at least in part because Andy has the crud. July 17 - This valley which comes to the coast at Bishop Point has long been known to contain Holocene volcanic fragmental debris. Today's reinvestigation found lava flows of Holocene age sandwiched between probable Pleisotocene deposits and the pyroclastic debris. We were also able to recognize several different ages of mid to late Pleistocene flows. This further reinforces the newfound appreciation of the vigorous nature of Makushin volcanism in the last few to several thousand years.
