Underground mining. Most of the gold was below the surface. The miners first had to thaw the permafrost before they could dig. A fire burning all night was used to soften the ground. This would then thaw to a depth of about 14 inches and the gravel could be removed. The process was repeated until the gold was reached.

Placer gold mining peaked about 1852. By 1860, gravel that would pay to work by these methods was now hard to find and gold production declined. Seeking increased mining efficiency the use of water in motion was further exploited.
mining operation generally is small, the combined acreage nationwide is substantial. Nearly one million acres were affected by sand and gravel mining in the U.S. in a recent 40-year period. Less than a third of these acres were reclaimed. In Minnesota, sand and gravel mining is increasingly viewed as a temporary use

Highlights of Mine Reclamation Efforts Around the World _____ Practices related to reclamation of mining lands have improved significantly in recent years.. Once a mine has been closed, the goal of the mine reclamation plan is to minimize the impact of the mine on the local environment.
Wetland Best Management Practices (BMPs) . In the plains, and some intermountain valleys, gravel mining has altered floodplain soils and hydrology. During earthwork in mining areas, it is possible to encounter acid rock spoils and other materials that are toxic to aquatic ecosystems when mobilized. If you are working in any of these areas, it .
Sand and gravel mining commonly occurs in large open pits. Typically, sand and gravel are relatively dry and removed with bulldozers, front-end loaders, and other conventional construction equipment. However, mining may occur in areas with a high water table. In this case, sands and gravels are removed by a mining method known as dredging.

These management practices can be applied to any surface mining activities that expose large amounts of soil. Cost Sand and gravel pit mining is very expensive so it is best to take into consideration all costs before initiating mining activities.
Practices (BMPs) for all types of nonpoint activities (i.e. farming, forestry, urban development and construction) nonpoint source pollutants can be reduced. Sand and gravel mining operations can potentially cause off-site impacts to water quality if site planning and BMPs are not factored into every aspect of the mining operation.

Gravel Mining gravel mining is legal with the proper permits, but it is not desirable in an Ozark stream. Studies conducted on Ozark streams in 1999 have shown that the hole in a stream caused by gravel removal causes the stream to move gravel from upstream into the hole, eroding the bottom and banks of UPSTREAM neighbors.
