TUPPER LAKE — Even with gray skies outside, the atmosphere inside the L.P. Quinn Elementary School couldn’t have been brighter as Friday’s Adirondack Day festivities carried on throughout the morning and afternoon.

This was the 20th anniversary of the event in Tupper Lake, and this year’s theme was “Adirondack Nights.”

Children from pre-K through grade 5 participated in a wide variety of activities, including watching an African music performance by the Badenyah Drum and Dance troop, building houses for bats, running obstacle courses, making terrariums, mushroom growing, debating about wolf species reintroduction, a puppet show, a nighttime sensory room and an owl animal encounter.

In an email, teacher, science curriculum coordinator and Adirondack Day coordinator Bridget Brown said that the day, which began in 2004 “to celebrate this beautiful place we call home,” also serves to honor the memories of physical education teacher Alice Grulich and her husband, Paul, who died in a plane crash the same year as the first Adirondack Day. The Grulich Garden, of which they are eponymous, is always involved in the day’s celebrations.
