The Friends of the Dundee Natural Areas’ annual Moonlight Walk will return Friday, July 19, at Jelke Creek Bird Sanctuary on Boncosky Road in Sleepy Hollow.

The event will feature a presentation from astronomer Andrew Rosado of the Northwest Suburban Astronomy Club. He will set up a telescope to share in-depth moon viewing. New for this year, Friends volunteer Don Purn will discuss the insects he attracts with a black light.

Friends of Dundee Natural Areas board members will lead the group on a moderate informative hike of Jelke’s trails. Bring a flashlight, bug spray, water, binoculars and folding chairs. Long sleeves and pants are recommended, flip-flops are discouraged.

This event is free and open to the public, but donations will be accepted. For more information, visit friendsofdundeenaturalareas.com/events.
