2022 Map of Shamrock
USGS Topo · Published 2022About this map
Shamrock serves as the primary named point on this high-plains landscape in eastern Adams County. The terrain is defined by the drainage patterns of Sand Arroyo Creek and its various tributaries, including W Fork San Arroyo Cr and Hoffman Cr, which carve through the undulating topography. In an area where water management is critical to the agricultural and ranching lifestyle, Simpsons Reservoir stands out as a key landmark in the northern portion of the quadrangle.
