Dahlia Shoals
 

Figure 7.2 - Oblique view looking southeast over Ile Aux Gallet with Dahlia Shoal in background. The rougher relief (of cobbles and boulders or outcrop?) occurs in water depths less than 12-15m. Limestone outcrops are reported from Ile Aux Gallet underwater observations(Somers, 1968). In deeper water patches and re-entrants of smoother morphology indicate depositional sites (sand?). Distance across the bottom of image is about 2.1 km.
