Fire and Water: Recent mafic volcanism of the central Oregon Cascades

COGS Central oregon field trip.png

This is a Central Oregon Geoscience Society field trip.

This field trip will explore recent mafic volcanism in the McKenzie Pass and Santiam Pass areas, with a focus on the Sand Mountain volcanic field. We will look at recent lava flows and tephra deposits, and at rivers, lakes, and groundwater that have been shaped by volcanic activity. We will also discuss hazards associated with mafic volcanic activity, including forest fires, disruption of water routes, and damage to infrastructure, agriculture, and tourism. 

Our sister club Central Oregon Geoscience Society (COGS) has extended an invitation for this field trip to GSOC members. This offers a great opportunity for meeting fellow geology enthusiasts and for building ties between our two organizations. More information and registration on the COGS website.
