Natural wonders of the American West have been preserved for future generations in the National Parks system. Two such wonders are Utah's Zion and Arches National Parks, which feature wonderfully different attractions. Maggio hiked both in 2015: the scorching hot Devils Garden in Arches and the narrow ridge trail to Angels Landing in Zion, a trek not for the faint of heart. The two movements are his musical distillation of these incredible experiences. Dedicated to the RoseWind Duo (Clifford Leaman, saxophones, Scott Herring, marimba), who have made video performances available on YouTube: Devils Garden / Angels Landing.
