2022 Triangle of Doom Take Two



Friends of the Pleistocene
Pacific Cell
2022 Field Conference
Announcement Number One

The conveners of the 2022 Pacific Cell Friends of the Pleistocene Field Trip announce the dates for the 2022 event.

Please set your email vacation announcements now for the weekend of 26-28 August 2022 as you may be away from the office, in the field, exploring fascinating new interpretations of Quaternary old to modern evidences of tectonic, hydrologic, and anthropogenic process in the region of the Mendocino triple junction (A.K.A., the Triangle of Doom; Hemphill-Haley et al., 2006).

This trip will be a 2 ½ day excursion in southern and central Humboldt County, California.

On Friday 26 August, at the coast near Petrolia, CA, we will learn about the first peoples of the region, the tectonic setting, recent geodetic work, and evidence for prehistoric to historic earthquakes.
On Saturday 27 August, near Hydesville and Shively, CA, we will review fluvial terrace mapping in the Van Duzen and Eel River valleys and how those terraces have been offset during earthquakes.
On Sunday 28 August, at the headlands of Table Bluff, west of Loleta, CA, we will hear about recent work around Humboldt Bay that includes evidence for coseismic subsidence, prehistoric human occupation, and the challenges that we face to construct modern infrastructure in an active tectonic and tsunamigenic setting.
