Join local Eagle Scout Sean Gallacher for a geocaching exploration of Redmond’s Historic Core and other historic sites from 10 a.m. to noon July 26. The event will start at the Old Redmond Schoolhouse Community Center (16600 N.E. 80th St.), a historic landmark.

At this free, family friendly event, participants will visit many locations in Redmond’s Historic Core while using their personal geocaching devices, such as a GPS device or GPS-enabled cellphone to locate hidden treasures and information.

At 10 a.m., Tom Hitzroth, chair of Redmond’s Landmark Commission and local historian, will kick off the event by sharing events from Redmond’s rich history before participants select their own routes to locate geocaches. At 11:50 a.m., participants will return to the community center to be entered in a drawing for an event prize.

For people new to geocaching, participants will locate geocaches using coordinates. At each location, participants will search for a container or access virtual information that describes the historic significance of the site. “Geocachers” often log their find at the site and in their personal log. Some geocaches also include small prizes that participants take and swap. GPS-enabled cellphone users should select and preload a geocaching application in advance.

Parking is available at the community center and on the street. An overflow parking lot is located on Northeast 80th Street, one block west of the community center.

This event will help Gallacher complete his leadership goal as a scout by providing him the opportunity to lead a team of volunteers and coordinate a community event.
