There will be a Night Hike through Sodalis Nature Preserve on July 26, but reservations are required for this free nature program.

The Night Hike will be 8 p.m., starting in the parking lot of Sodalis Nature Preserve, 819 Ely St.

Participants will learn about the Sodalis success story, the endangered Indiana bat and the other plants and animals that make their home at Sodalis. Interpretive guide Gale Rublee takes participants around the 2 1/2 mile paved loop making seasonal observations, telling about the bats and playing a “Bat & Moth” game at the amphitheater, exploring some of the gated mine entrances then ending at the stone fireplace with a final story.

Rublee had been a volunteer teacher naturalist at Shaw Nature Reserve in St. Louis for 13 years. She is a storyteller, actor and coordinator for the Bluff City Theater Youth Education Theater Initiative (YETI).  She is also an outdoor educator at Gardner Camp in Hull, Ill.
