This field trip will investigate interacting hazards on Mount Hood, a ‘Very High Threat’ volcano in the Cascades arc. We expect to host a team of ~25 scientists spanning career stages and disciplines, who will apply traditional field techniques, aerial drone surveys, and geophysics, to collect new data and discuss outstanding science questions. Primary field targets where we aim to collect new data include (1) a near-summit pyroclastic surge deposit from the Timberline eruption, (2) sediment aggradation and fluvial dynamics in the White River associated with recent eruption deposits (including remobilization of volcanic sediment by atmospheric rivers), and (3) characterizing evidence of geologically recent active faulting recorded by near-surface soils. Potential additional targets, pending interest and time, are (4) debris flows and landslides in the Columbia river gorge, (5) regional magmatic uplift of the Cascade arc front, and (6) monogenetic volcanic processes. The trip will be organized with office days to enable processing and analysis of data. It will involve projects that all participants can contribute to, with the goal of developing research products, new ideas, and new collaborations. We will be collecting field data as a group in collaboration with StraboSpot, an NSF-funded open source framework for collecting, storing, and sharing field data. We will provide training on use of this application as part of the trip.
Dates: Activities span July 20-29, 2026, with travel days before and after. We will be staying at the Mt Hood Resort in Government Camp, Oregon. Participants are required to attend a virtual pre-trip planning/onboarding meeting.
