Sinai occupies a quiet expanse of the high plains where the horizon stretches wide enough to swallow the sun each evening in a slow, bruised wash of violet and gold. It lies 12.9 miles west-southwest of Brookings, SD (from Brookings, SD: bearing 249°T), and is situated 7.9 miles southwest of Volga. The land here is defined by its flatness, a vast, open prairie that breathes with the changing seasons, marked primarily by the Brookings County Waterfowl Production Area that sits directly upon the landscape like a sanctuary for the wild. Only a mile away, the surface of Bolstad Slough mirrors the shifting clouds, providing a cool, still counterpoint to the endless grasses that ripple under the constant, restless wind. On the clearest days, one might imagine the distant, hazy suggestion of The Coteaus rising far to the west, though the immediate world remains one of earth and sky, unburdened by the clutter of larger, louder places.
History in Sinai suggests a deliberate, sturdy endurance, born from the persistent labor of those who first broke the sod to find a living in the soil. The economy remains tethered to the rhythm of the harvest and the stewardship of the surrounding fields, where the patterns of agriculture dictate the pace of every day. While Battle Creek flows nine miles distant, the influence of the region is felt less in the rush of water and more in the steady, quiet work of the people who maintain the grain elevators and the local roads. Life here moves with a measured gravity, a reflection of a landscape that demands patience and rewards the observant eye with the subtle, shifting colors of the prairie grass as the light wanes.
