Caswell-Massey created the Yellowstone Forever Collection featuring living floral scents from Yellowstone National Park, in partnership with Yellowstone Forever, the official non-profit partner of Yellowstone National Park. Yellowstone Forever’s mission is engagement and support through education and fundraising for the park to ensure Yellowstone remains an incredible resource for generations to come.
Mammoth is derived from living floral captures near Mammoth Hot Springs, including evening primrose and evening star lilies that only grow in this region of the park, blooming at night in early spring when the snow begins to melt. Mammoth’s thermal features make it one of the first areas in Yellowstone to thaw in the Spring. This fragrance captures the spring thaw with fresh citrus and aromatic notes of sage, mountain haygrass, cedar and earthy undertones. This woody aromatic fragrance features top notes of mountain hay-grass and citrus; middle notes of sagebrush and cedar and a base note of wet fertile earth.
