Wasson Bluff (Wasson's Bluff), Parrsboro, Cumberland Co., Nova Scotia, Canada

A shoreline exposure accessible at low tide. The rock alternates between red sandstone and gray to brown Triassic basalt. The sedimentary rocks are famous for containing dinosaur fossils from near the Triassic-Jurrasic boundary (near the time of the extinction). The fossils are protected by law through the Special Places act.
Excellent minerals, particularly vibrantly colored chabazite, have been known for about 150 years. The orange and red chabazites are generally considered some of the finest examples of that mineral in the world.
Note that old references from the 1800s do not use Wasson's Bluff as the name of this locality. Swan's Creek (or some variant of spelling) is used instead, but it is clear from the minerals descriptions that this is the same as what is now Wasson's Bluff.
