Since 2015, The Crossing has held a residency at the Warren Miller Performing Arts Center in Big Sky, Montana. Collaborating with John Zirkle, Executive Director of WMPAC, the residency has been a kind of think tank for new choral music, ranging from the creation of new works and film projects to composer and conductor education initiatives offering coaching from world-renowned composers and Donald Nally. Guest composer mentors have included Gavin Bryars, Gabriel Jackson, and Ted Hearne, while composers creating new work include Shara Nova and Michael Gordon. Shara's most recent work for The Crossing, Titration, premiered in Big Sky August 2022 and went on to the Ventura Festival, NPR's Tiny Desk, and a recording and performance in Philadelphia. 

The Crossing has established many friendships in Big Sky made through their "Community Sing," collaborations with Bozeman's professional choir Roots in the Sky (led by Andrew Major, former Fellow of the Big Sky Composer Initiative) and through John Zirkle's visionary work with Barbara Rowley and Taylor Middleton, on whose farm they workshopped Ted Hearne's Farming, as well as with Jill and Loren Bough, on whose ranch at the Smith River The Crossing filmed To the West, based on music of Michael Gordon developed at WMPAC. Additional adventures have included projects with Story Mill and Tinworks in Bozeman, performances in Fort Benton and at Montana State University, outdoor performances of The Forest at Jack Creek Preserve, and a concert on the top of a mountain at Cache Creek Outfitters of works by Ayanna Woods, Gavin Bryars, and David Lang whose in nature was developed in collaboration with John Zirkle and WMPAC as one of The Crossing's first pandemic works.
