Arboretum observations: Ness Elementary School second-grader Jace Nassett, center, shows off his newfound treasure of Morgan red maple leaves to classmate Adam Woolbeck, while Preston Bresnee, right, searches the ground at the John A. Finch Arboretum. Warren Hanson’s class spent Tuesday morning working on observational skills, noticing the color and shapes of leaves and tree trunks. Hanson said when the students return to class in Spokane Valley, they will be asked to write a poem about their arboretum visit.
