Special Earth Day activities can be found at Wallowology in Joseph on Friday, April 22, from 10 a.m.-3 p.m.

JOSEPH — Wallowology, which runs a natural history discovery center in downtown Joseph, has planned two days of events in honor of Earth Day.

On Friday, April 22 — the official Earth Day — visitors to the center, 508 N. Main St., can help plant in the new garden, explore exhibits, listen to stories and take part in other family-oriented Earth Day activities. The center is open 10 a.m.-3 p.m.

Events continue on Saturday, April 23.

At 9 a.m., Wallowology is organizing an Earth Day service project to clean up baling twine found on the roadsides and in fields. This will help protect osprey from getting tangled in the twine, according to Wallowology.

To participate, meet at the center in downtown Joseph at 9 a.m. to pick up a route map and twine collection bags. Groups will head out by car to collect and then return to the center to celebrate their hard work. No registration is required.

For those who want a different type of adventure, naturalist Judy Swank will lead a hike up the East Moraine beginning at 9 a.m.

Participants will learn about local ecology during the two-hour hike at a family-friendly pace. Meet at the roadside trailhead between mile markers 4 and 5 on the Wallowa Lake Highway (used to be “green gate”). This hike is free, and no registration is required.
