Olympic Mountain Formation

Processes 1. Subduction of Juan de Fuca Plate 2. Accretionary Wedge of Mudstones, limestone, sandstones and conglomerates 3. Obduction of oceanic crust 4. Rising of sediments through oceanic crust (the pimple hypothesis)

1. Subduction of Juan de Fuca Plate 2. Accretionary Wedge of Mudstones, limestone, land sediments

3. Obduction of oceanic crust Some Oceanic Crust Lifted OVER Accretionary Sediments Oceanic Crust

4. Rising of sediments through oceanic crust (the pimple hypothesis) Oceanic Crust Accretionary Sediments are less Dense and rise up through Basaltic Oceanic Crust Basaltic Crust erodes, now only located as a donut around east and North edges
