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.

Fox one of the ranches saddle horses.

Like your fingernails a horse’s hoof keeps growing. If it doesn’t wear down naturally, it is necessary to trim it. If it gets worn down faster than it can grow, it needs an iron shoe to protect it. In trail-driving days, cowboys often left their horses unshod unless they got sore-footed.
