Big River Journey Field Trip

The various stations for Big River Journey are shown below. Each shift lasts approximately 5.5 hours, but that varies depending on station and date. This field trip runs on volunteer power, we couldn’t do it without all of your help!

Crime Lab

Volunteers will help facilitate student learning through problem solving - students will figure out how pollution got into the river (the answer? Storm drains!) and what they can do to prevent this river crime in the future.

Ecosystem Ottersystem

Assist a park ranger in engaging students as they learn about river otters and the importance of flooding to maintain a functioning ecosystem.


Geology Station

Assist a park ranger with the presentation of the "Mystery of the Disappearing Waterfall,” an interactive activity about the movement of the falls on the Mississippi River over the centuries.

Birds Station

Volunteers help students use binocular and spot birds along the river. No experience is necessary, but an enthusiasm for birds and a willingness to facilitate student learning is a must.


Fort Snelling Water Quality Lab

Work with River Educators to help students assess water quality at the confluence of the Minnesota & Mississippi rivers. Students will use turbidity tubes and test tubes to measure pollutants and compare two key watersheds. This is a NEW station for fall 2019!

Roving Monitor

Volunteers assist during station transitions, facilitate safe boarding and unloading of the boat, and other miscellaneous duties as assigned. In the event of a staffing shortage at one of stations, the roving monitor will likely be asked to assist at a designated station for the day.
