With the backdrop of Yosemite National Park, this artwork was inspired by John Muir, one of America’s most famous and influential “Outdoor Enthusiasts”. Born in 1838, he was one of the Fathers of America's National Parks and a truly unique “poetico-trampo-geologist-botanist and ornithologist-naturalist”!

His letters and writing contain such gems as the one inspiring the title of this artwork, "The mountains are calling and I must go, and I will work on while I can, studying incessantly", a true calling.
