It lies 18.6 miles south of West Des Moines, IA (from West Des Moines, IA: bearing 183°T), and is situated 9.6 miles west-south-west of Indianola. The terrain here is a gentle, undulating prairie, softened by decades of cultivation and the occasional stand of mature oak and walnut trees that break the horizon. Creeks, narrow and often veiled by overhanging branches, carve shallow paths through the earth, their murmuring a constant, low hum beneath the vast, open sky. In the late afternoon, the sun casts long, golden shadows across the fields of corn and soybeans, imbuing the landscape with a quiet, almost sacred luminescence. The story of St. Marys is one of quiet persistence, deeply entwined with the agricultural rhythms that have shaped this corner of Iowa. Settled by hardy pioneers drawn to the fertile soil, the community has long depended on the bounty of the land, its economy rooted in farming and the services that support it. While no grand monuments mark its past, the sturdy, unpretentious architecture of its homes and businesses speaks of a practical, enduring spirit. Local traditions, though subtle, are woven into the fabric of everyday life, evident in the shared meals at the community hall and the careful tending of gardens that spill over with summer blooms.
