The Whitman Mission, 328 Whitman Mission Road, has two events this weekend.
Master fabric artist Susan Swayne will demonstrate weaving from 1-4 p.m. Saturday. There will be a loom available for visitors to try weaving.
On Sunday a new event, Stinky Soil & Solar Power, will be held. There will be a behind-the-scenes tour of the park's solar and composting facilities, as well as hands-on activities.
Visitors can plant native rye grass using park compost, learn about worm composting, observe a solar-powered toy car and try cooking in a solar oven.
The mission currently composts nearly 90 percent of its waste and uses solar panels for 30 percent of its energy needs. In 2006, the mission became the first site to win three top awards from the Environmental Protection Agency in a single year. In 2007, Whitman Mission won the top environmental awards from the National Park Service, the Department of the Interior and from Washington State.
Whitman Mission is 7 miles west of Walla Walla off Highway 12. Take the Spalding exit. Spalding is a short road that ends at old Highway 12. Turn right onto the highway and follow the signs. For information, call 522-6357.
