| Shi Shi Beach, Clallam Bay Washington |
This week I traveled to Shi Shi Beach in Clallam Bay
Washington where the Juan de Fuca and North American Plate converge. Here you
can see the results of the Juan de Fuca plate being pushed underneath the
continental landmass of the North American plate in a reverse fault. The forces
happening at this margin are compressive as we can see anticlines formed into
the ridge just off the beach shoreline. For the majority of this ridgeline, the
fault is dominated in the structure. The fault has faces that were not a form
of heat and pressure, but more of breaking and jutting upwards over the
converging plate. The surrounding hills seem to have been formed through
pressure forcing the rock to fold and rise higher in the air over long periods
of time.
