Explore Crissy Field Marsh the best way possible, from the inside! Participants will have the rare opportunity to put on hip-waders, tromp into the marsh to collect mud samples, and bring their findings back to our Urban Ecology Lab for a closer look under the microscope. This program is for all those envious adults who watched their child participate in this program in the past and said "I wish I could have done that when I was a kid!"
