JEFFERSON — At Hidden Valley Nature Center’s open house at 10 a.m.-4 p.m. Sunday, Oct. 2, there will be something for everyone.

Recent rains have resulted in one of the best mushroom seasons in decades. Starting at 2:30 p.m., Roger Monthey, from the U.S. Forest Service, will lead a mushroom walk in search of edible and medicinal mushrooms, as well as those you should avoid.

From 11 a.m. to 1 p.m., John Pranio and Toki Oshima will sing and play a variety of instruments. Their music is eclectic, including contradance music, old-time country songs, swing and country blues.

Kids time is 1-3 p.m. Author Coreysha Stone and Megan Welch will lead kids on an exploration of the forest. Stone will read from her book “Let’s Go For a Woods Walk,” followed by a sensory hike, where the focus will be on animal tracking, trees and the predator-prey relationship.

Registered Maine Master Fishing Guide Sean McCormick will be on hand to teach how to tie and use your own flies. He also will give a fly-casting demonstration and visitors can try their hand (with their own rods) at nearby Little Dyer Pond.

All day the timber framing class will be preparing for the final assembly of the building its members have been constructing for the previous three days. By the end of the day, the building will be up.

Kirk Niese will lead a walk on the Working Forest at HVNC. He will introduce participants to the most prevalent, commercially valuable trees in Maine and their historical-current uses. The principles of low-impact logging, how to calculate a cord of wood or the number of board feet of lumber vs. saw logs, and how forests act as carbon sinks will be covered.

Maine Master Naturalist students Chuck Dinsmore and Bambi Jones will help folks learn to identify trees using a handy key.
