Almost a dozen volunteers helped pick up trash, trim the greenery, and fix some of the structures.
They're getting the grounds ready for more than 1,000 fifth graders. On Monday, they will descend on Trumbull Creek from as far as Eureka and Charlo.
Conservation, Forest Service, and timber volunteers are going to teach them about this natural landscape from several points of view.
"I'm actually really excited, like, this is great to be outside with natural resources instead of inside with natural resources is always good," said Kari Musgrove, one of the volunteers.
Next Saturday, May 10 you can catch a show with logging equipment demos and the Forest Service spotted bear ranger district mule pack string at this same spot for free.
