- **Event Name**: Geology of Baltimore
- **Event Start and End Date**: Sun, 19 Apr, 2026 at 11:00 am – Sun, 19 Apr, 2026 at 12:30 pm (-04:00)
- **Event Description**: 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 Sam Glasscock 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 rocks that formed roughly 3.8 billion years ago in Earth’s history and were 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?
