Currently, Jill is working closer to home on an important conservation project focused on freshwater mussels in Ottawa’s rivers.

Jill’s dedication to understanding and protecting these vital freshwater habitats is an extension of her passion for environmental stewardship, which has fueled her global expeditions and work. But also has made her realize there’s a lot to uncover right at home, making this one of her favorite cave explorations yet. When not on expeditions at home and abroad, she’s also touring her latest film globally called, Diving Into the Darkness: Never Cave into Fear, which is set for streaming in 2025.
