1967 Map of Allen

Tracing the northern portion of the map, the Old Indian Treaty Boundary cuts across the terrain, a significant historical marker separating tribal lands. Cultural sites such as Greenleaf Cem, Tea Cem, and the youth camp at Camp Sasakwa are scattered throughout the wooded draws and ridges between Little River and the Canadian. The topography is defined by prominent elevations like Little River Hill and Osage Hill, overlooking the river bottoms and the resource-rich plains of the Bilby area.
