dredging streambeds may be an effective technique for mining salt

In order to make maximum use of pre-mining planning, as a tool for resolving a conflict over the company's proposed operation, more » an extensive cooperative planning effort was initiated. The aggregate deposit is located in a highly visible site just off the Denver-Boulder Turnpike at the entrance to the city from Denver, and adjacent to a residential portion of the city.

The site contains a deposit of high-quality sand and gravel considered to be one of the best and largest known deposits of aggregate materials in the Front Range area. This case study details reclamation planning for the Flatiron Companies' South Boulder Creek Park Project in Boulder, Colorado. Foliar deficiencies in phosphorus, potassium and several micronutrients suggest that availability of nutrients and potential mineralization explain the observed differences in site productivity. Soil profile development below the surface soil was nonexistent on all sites and differences in soil texture and color did not adequately explain observed differences in site productivity. more » These values indicate that growth on many mined lands is comparable to growth on adjacent non-mined lands.
