1963 Map of Mud Spring

About this map

Mud Spring and Circle Bar Spring provide critical water sources in this dry landscape at the boundary of Petroleum and Musselshell counties. The area is defined by a dendritic drainage network of intermittent streams, where Maginnis Creek and North Maginnis Creek carve through the terrain. Evidence of water management is visible at a reservoir with a Spillway Elevation of 2996, located near the headwaters of Mud Creek. The geography reveals a ranching landscape reliant on named coulees and springs, such as Salt Sage Coulee and Bar Coulee, which dictate the movement and settlement patterns across these central Montana plains during the early 1960s.
