1969 Map of Thatcher Hill

About this map

Gentile Valley and the eastern slopes of the Portneuf Range define this Idaho landscape at the intersection of Caribou, Franklin, and Bannock Counties. The Bear River winds through the valley floor, supporting a local community centered around the Thatcher Ch and nearby Thatcher Cem. The map reveals a transition from the agricultural lowlands of Gem Valley to the high, drainage-carved terrain of the west, where named watercourses like Densmore Creek, Smith Creek, and Jacobson Creek descend from the peaks. The infrastructure of the era is captured through a network of secondary roads and more remote access points marked as Trail or Jeep Trail, including a significant route through Mine Hollow. This survey provides a look at the rural Idaho interior before modern development, highlighting the balance between valley settlement and high-altitude ranching or mining access.
