You've probably passed this area dozens of times, but didn't realize what is not seen and certainly didn't realize what was here before. Let's use the trail to take a closer look at the ponds, their function, and their artistic embellishments. We'll also talk about the history of the Milwaukee Road, one of the largest rail yards of its time, its thousands of dedicated workers, and the project to honor them. We'll end by enjoying the walking paths, riverside trails, and abundance of native plants on this section of the trail. The walk will be led by Michelle Kramer of Menomonee Valley Partners. Class fee is non-refundable.

Location: Park next to Charter Wire on 36th and Milwaukee Road, just west of the 35th St. Viaduct and Canal Street.
