[I am, of course, biased in this regard, but I also like well-presented metrics – and use cases being met are my favourite!]

imagery / photos - aerial - remotesensing sensing - LiDAR - the expression of the Seattle Fault on southern Bainbridge Island
map and model - Fold and thrust belt interpretation superimposed on the aeromagnetic map shown in Figure 4. Interpreted reverse faults bear hachures. Unadorned, solid lines show the positions of other boundaries, many of which we interpret as the boundary between the upper and lower Crescent Formations, especially where they are positioned parallel to and between two reverse faults. All lines closely follow linear maximum gradients identified from the pseudogravity map (Figure 5), however, dotted lines indicate linear features that are less certain. Solid boundaries and reverse faults in the Olympic Mountains (bordering the area marked as mapped upper and lower Crescent Formations) also have geologic mapping support. Labels identify major tectonic elements corresponding to the text and the light brown lines indicate the positions of the geophysical models in Figures 8-10. KA, Kingston arch; SFZ (gray area), Seattle fault zone; SU, Seattle uplift.
graphic / map - hillshade and annotations showing the Seattle Fault Zone, Puget Sound
map and model - Contoured isostatic residual gravity in milligals (mGal) for the Puget Lowland. Contour interval is 5 mGal, and small crosses show location of data points constraining the gravity grid. The bold contour highlights the potential shape of the Seattle basin as discussed in the text. Blue-outlined transparent polygons are waterways. Brown lines show locations of models in Figures 8-10 (A–A′, B–B′, and C–C′, respectively). Thick, gray lines (labeled 1, 2, and 3) show potential locations of the Siletzia eastern boundary from pseudogravity gradient analysis shown in Figure 5 and discussed in the text; the solid line (3) indicates the most likely position. EB, Everett basin; EO, small Eocene basin; HC, Hood Canal; KA, Kingston arch; M, Monroe; MB, Muckleshoot basin; NB, North Bend; OS, metasediments of the Olympic accretionary core; PP, Pulali Point; PS, Puget Sound; RF, Rattlesnake Mountain fault zone; S, Seattle; SB, Seattle basin; SFG, Seattle fault gravity gradient; SU, Seattle uplift; SWIF, Southern Whidbey Island fault; TB, Tacoma basin.

H/T Shawn Willsey
“Hike up scenic Carbon Canyon in the Grand Canyon with geology professor Shawn Willsey to investigate the sexy and magnificent rocks exposed along the Butte Fault. Learn how this fault formed, reversed its direction of movement, and made the East Kaibab Monocline…”

Dr. E.F. -Lalo- Guerrero

I am beyond thrilled to share that I've accepted the position of Hazards Geologist with the #Oregon Department of Geology and Mineral Industries (aka #DOGAMI), based in the #Portland office.

So excited to join a great team and for the opportunity to continue to grow and learn as a research scientist with a focus on furthering #seismichazard and #geologicmapping programs throughout the state.
