About this map

St Peter stands as a focal point in this high-plains landscape where the southern reaches of the Sullivan Valley meet the rising slopes of Telegraph Mountain. This 1983 survey illustrates a transition from established mission life to the open ranching country defined by the Birdtail Divide. The presence of Sullivan School and the Cem near the St Peter Mission Road suggests a community structure built around education and faith in a territory otherwise dominated by prominent landforms like Lionhead Butte and Haystack Butte. The drainage patterns of Mission Creek and Sullivan Creek reveal the essential water sources that dictate movement and settlement in this portion of Cascade County. A network of unimproved roads and fence lines, meticulously recorded, provides a clear view of the rural property boundaries and infrastructure serving the local agricultural economy during the late twentieth century.
