Figure F1. A. Tectonic setting of Leg 204 in the accretionary complex of the Cascadia subduction zone. The box shows region of Figure F1B. B. Bathymetric map in the region of Hydrate Ridge. The box shows location of Figure F1C. Locations of ODP Site 892, seismic Line L2-89 (shown in Fig. F2), north Hydrate Ridge (NHR), south Hydrate Ridge (SHR), and Southeast Knoll (SEK) are also shown. C. Detailed bathymetric map of the region of Leg 204. Leg 204 sites are shown along with their site numbers (e.g., Site 1244) and precruise designation (e.g., HR1a). Bathymetry from Clague et al. (2001).
