2010 Map of Shamrock

About this map

Sand Arroyo Creek and its various branches, including the West Fork Sand Arroyo Creek, define the drainage patterns of this high plains landscape at the start of the twenty-first century. The area around Shamrock is characterized by a precise rectilinear road grid, reflecting the systematic land division of eastern Colorado. This network includes local thoroughfares such as Shamrock Mile Rd, Hard Money Mile Rd, and Paperbirch Rd, which facilitate movement across the sparse terrain. Water management is a central feature of the local geography, represented by the presence of Simpsons Reservoir and Hoffman Creek. These water bodies and the accompanying drainage ways are the primary landmarks in an otherwise open agricultural or ranching environment, illustrating the critical role of water resources in the development of the region.
