Mildred E. Grierson Memorial Wildlife Sanctuary

Find nesting ducks at a 5-acre spring-fed marsh pond.

This preserve features a 5-acre spring-fed marsh pond, unusual for its alkaline waters, which is a nesting site for ducks. A 13-acre dense hardwood forest dominated by black birch thrives nearby. Preserve can be accessed from the orange trail of the Marian Yarrow Preserve or from Todd Road. Stanley O. Grierson donated the Mildred E. Grierson Memorial Wildlife Sanctuary in 1973 in memory of his mother.
