The Ridges Sanctuary in Baileys Harbor continues its Thursday lecture series and hosts a different type of “ladies’ night” this week.

The “Lake Lessons” Thursday speaker series held at Baileys Harbor Town Hall offers a program on June 26 on the historical archaeology of Rock Island and the Door Peninsula with Heather Walder, an archeologist and Ph.D. candidate at University of Wisconsin-Madison.

Archaeologists study glass beads to trace the movement of people and goods over time. In her dissertation research, Walder analyzed fur trade-era glass trade beads in order to understand technological innovation, population movement and social change during the 17th and 18th centuries in the Upper Great Lakes region.

For this lecture, Walder will discuss the historical settlement of people throughout the Door Peninsula and their relationship to the Upper Great Lakes region. This presentation coincides with the installation of a new exhibit on Rock Island which highlights findings from Walder’s research.

“Lake Lessons” programs take place at 7 p.m. Thursdays at Baileys Harbor Town Hall, 2392 County F, just west of Wisconsin 57. Admission is free, but donations are welcome.

Mothers and daughters — or grandmothers and granddaughters, too — can spend the night under the stars at The Ridges on an overnight females-only camping adventure June 27 and 28.
The camp-out, designed for girls ages 6 to 10 accompanied by a female adult, includes a night hike, campfire, breakfast and a morning bird hike. Participants should bring their own tents and camping supplies; marshmallows, cold breakfast and good times are provided.
Campers should meet at 7 p.m. June 27 in the Marshall Cabin at The Ridges. The event runs until about 8:30 a.m. June 28. The program fee is $30 per family for Ridges members, $40 per family for nonmembers. Space is limited and advance registrations are required.

Founded in 1937 as the first land trust in the state, The Ridges Sanctuary is at 8288 County Q, just east of Wisconsin 57, Baileys Harbor. To sign up for events or for more information, call (920) 839-2802 or visit
