About this map

The TTT Ranch occupies a central position in this corner of Johnson County, situated where the South Fork Powder River joins the main course of the Powder River. Surveyed in the late 1950s and field-checked in 1961, the landscape reflects a ranching economy supported by complex water management, including the Tisdale Ditch and numerous reservoirs like King Res. The presence of scattered Claypits and a Drill Hole suggests early industrial interest in the area's mineral resources, while the network of unpaved routes such as Bear Lone Road and Arminto Road 10 Mi. provided essential connectivity for remote holdings.

Erosion has carved deep landmarks across the terrain, from the dramatic Posey Canyon to named drainages like Telephone Draw and Frewens Draw. These features, combined with the presence of multiple Spring and Well locations, illustrate how vital permanent water sources were for sustaining livestock in the high plains. The transition between the township lines of T. 42 N. and T. 41 N. helps researchers pinpoint exact historic land parcels within this vast drainage basin.
