This year’s Earth Day celebrations at the Big Bear Discovery Center on Saturday include something for the entire family. The new mobile Forest Explorer van will be visiting, with interactive displays showing a healthy forest, as well as information for homeowners on how to thin trees in their yards and help to make neighborhoods firesafe. A group of youth volunteers, including a local homeschool group will be offering ongoing solar oven demonstrations and crafts between 10:00 am and 2:00 pm, and an adult volunteer will tell stories at 12:30 pm. The regularly scheduled nature walks will are leaving the bronze grizzly in front of the Discovery Center at 1:00 and 2:00 pm and the Adventure Outpost store will be open for browsing between activities. The Big Bear Discovery Center is on the north side of the lake at 40971 North Shore Drive, in Fawnskin. Call 909-866-3437 for additional information.
