A decade later, in 1919, Chase was one of the founders of the Woodstock Artists' Association, along with Andrew Dasburg, Carl Eric Lindin, Henry Lee McFee, and his former teacher John Carlson.
Among Chase's most important legacies were his students, including many who became renowned painters themselves: Elizabeth Saltonstall, Isabelle Hollister Tuttle, Ruth Haviland Sutton, Emily Hoffmeier and Anne Ramsdell Congdon.
Chase encouraged open-air painting classes, weather permitting, otherwise utilizing wharf cottages along the waterfront, reminiscent of his own tutelage back in the mountain shanties of Woodstock.
Back in Woodstock, he taught and helped to promote such future notables as Harvey Fite, Anton Refregier and Marko Vukovic.
Clearly influenced in his youth by American Impressionism and Post-Impressionism, he became more faithful to nature as his style matured, many of his later landscapes evoking a spiritual kinship with earlier Hudson River School masters like Albert Bierstadt, Thomas Cole and Frederic Edwin Church.
