A large iron ring hangs from a wall, set in place many decades ago. And right below, there’s a big stone step. Look closely to see a peephole near the top. Who was spying? Join geologist Kathleen Marasco to find the answer on this walk near the Inner Harbor. We will share the stories of rocks from many of our largest buildings and monuments, and you’ll discover how far away these beautiful slabs of stone traveled to find a home here in Baltimore.
On this 1.25-mile walk, view structures built with igneous, sedimentary, and metamorphic rock formed roughly 3.8 billion years ago in Earth’s history and erected during the last 200 years of American history. Who knew you could see ancient fossils, touch a stone almost as old as the Earth, and get a feel for Italy all in downtown Baltimore?
Our trip leader, Kathleen Marasco, holds a Bachelor’s degree in Environmental Geology and a Master’s in Secondary Science Education. The tour should take approximately 1.5 hours to complete.
