1951 Map of Lone Mountain

About this map

Lone Mountain dominates the central landscape of this 1951 survey, a prominent elevation in a terrain defined by ridges and drainages within the Missouri River Basin development area. To the south, Countryman Peak serves as another significant high point, overlooking the geographic transition toward Beef Gap. The presence of Sage Hen Springs and the headwaters of Sage Hen Creek in the northern reaches suggests the critical role of reliable water sources in this high-plains environment. This sheet is particularly useful for understanding the historic topographic layout before late-century changes, capturing the relationship between named landmarks like the interestingly titled Pocket Vice and the surrounding township boundaries. The map was produced through multiplex methods by Ryall Engineering Co., reflecting mid-century advancements in aerial photogrammetry for western land management.
