Episode summary introduction: In this episode of Backyard Geology, Serena takes you to Hamilton, ON to look at the sedimentary structure that locals call “The Mountain”. The Niagara Escarpment is a steep cliff face that bisects southern Ontario. The cliff face is home to scenic hiking trails and countless waterfalls. For geologists, the Escarpment showcases over 100m of relatively undisturbed sedimentary rock beds, hosting fossils from an ancient tropical sea that once existed on the edge of Laurentia.

Host Information: Serena is a Canadian graduate student currently studying geochemistry at the University of British Columbia in Vancouver. Her research focuses on isotopic analysis of Hawaiian volcanos to understand the dynamic and complicated evolution of the Hawaiian mantle plume. She completed her undergraduate degree at McMaster University in Hamilton, Ontario, where the exposed sedimentary rocks of the Niagara Escarpment and enthusiastic professors quickly fostered a love for all things geology. Like other member of the Geology Podcast Network, Serena loves to talk rocks and is invested in sharing her love for our planet through podcasts, educational programs for kids, and even museum exhibits. Despite heavy seasonal rains in Vancouver, she is an avid cyclist, which unfortunately does not bode well with inevitable stop for round hounding, but is an excellent way to thoroughly explore the Earth and all its glorious geologic features.
