MONKTON — In the woods of the Willowell Foundation land in Monkton, artist Marela Zacarías is leading the local community in turning 1,024 square feet of reconstructed silo into a permanent sculptural mural installation. Zacarías’s project, called “Azimuth,” is part of a series of artist residencies at Willowell that interpret both pre-Columbian design motifs and Vermont’s natural environment. According to Zacarías, “Azimuth” “is meant to work as a meditation on transformation and an offering to nature.”
