Environmental Factors

Exposed mine tailings - 'slickens'

Exposed mine tailings - 'slickens' with high metals concentrations and acidic soils.

Environmental factors shape the landscape and habitats of Grant-Kohrs Ranch National Historic Site and the Deer Lodge Valley. Long before humans arrived geological processes, weather, and fire shaped this environment. More recently, natural processes have been affected by human activity. The valley has experienced many impacts including mining, ranching, and the development of towns and cities.

Several environmental factors are being monitored by National Park Service staff and researchers from other agencies or universities. The goal of montoring is to gather information for its use in science-based decision making and to ultimately preserve the park's resources.

Two cowboys on their horses.

Crusty old cowboys were mainly an invention of movies. Most cowboys were young, some only eleven or twelve. By the time they were in their mid-20s, most had taken up ranching on their own or found a less strenuous way of life. Yet, some kept cowboying as long as they could stay in the saddle.
