Geology Walk - Sedimentary Rocks
A 1.5 hour guided walk to learn about the geology of sedimentary rocks like limestone
Adult tickets $12
Two adult tickets $20
Youth ticket $6 (7-14 years)
Child ticket $0 (0-6 years)
Come explore sedimentary geology to learn how sediments tell us about Earth history, what fossils you can find in Kingston, and what is limestone anyway!
This is our 3rd annual geology walk but it’s different. This year we are focusing on sedimentary geology - that’s rocks made from eroded bits of other rocks (like limestone). We will also touch on the geology of sediments before they turn into rocks. We will also bring our rock and mineral collection for you to explore and learn from.
Date: August 16, 2025
Time: 10-11:30 am
Location: O’Connor Park at Old Quarry Road
Take your walk to the next level with an add-on additional educational resource of a pocket nature booklet on sedimentary geology, a geology kit, and/or rock samples.
All blue marble nature resources will be available for purchase during the guided walk.

What to expect when you’re exploring
Interested in joining one of the guided walking with blue marble events in Kingston, but not sure what to expect?
During these walks blue marble cofounders Cindy and Tara will entertain you with nature knowledge and activities. Each walk has a theme that will complement the location and season. But don’t expect to only learn about the walks theme.
For example, our walk on May 23, 2023 we explored the theme of birds at Lemoine point. Yes we talked about birds, bird behaviour, bird identification, bird habitat, and bird migration. But we also talked about native, non-native, and invasive species, different ecosystems, healthy forests, geology, zebra muscles, ticks, no mow May, and more.
Will we repeat some info? Yes, because some facts are too cool not to share with everyone.
Have your own nature questions? We encourage participation during our walks. Ask us questions and we will answer to the best of our ability!
Meet your guide
Tara is one of those people you find sharing knowledge of the natural world at unsuspecting times and who has a natural curiosity about the Earth. It was a childhood in the beauty of the 1000 Islands and Frontenac Provincial Park that sparked Tara's love for rocks and water and which flamed her desire for environmental knowledge to answer why things are the way they are. This desire led her to a career as a hydrogeologist, working with groundwater and geology in research, consulting, and conservation within Ontario. Tara spent 13 years learning about and working in environmental sciences, and is now ready to take what she has absorbed to inspire others within Ontario to reconnect with nature and develop their own undying curiosity for everything environmental.
During the walk you can ask Tara about anything, but she gets particularly excited about rocks, water, and turtles!
