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.

Look at the addition added on to the Kohrs house in 1890.

The Kohrs were optimists. When the 1890 brick addition was built onto their home, they had the house wired for electricity, even though it wasn’t available at that time. They got electricity a mere two years later.
