PhD student David Farsky, working with Dr. Michael Rowe, completed some fieldwork last weekend. David sampled basaltic scoria from the 1886 Tarawera eruption, basaltic tephra from an older eruption underlying the Rotoiti ignimbrite, pumice from the Rotoiti ignimbrite, and pumice from the Kaharoa ignimbrite. The pictures with the geothermal lakes and springs show Jimmy, another PhD student, who is looking into the surface expression of the geothermal activity.
