摘要

In 1995, the U.S. Bureau of Mines and the U.S.D.A. Forest Service, Alaska Region, Chugach NationalForest entered into an three year Interagency Agreement to survey mineral materials on the Forest.Following closure of the Bureau of Mines and transfer of Alaska personnel in 1996, the work proceededunder the auspices of the Bureau of Land Management. Field work was conducted in 1996 with 27 sitesbeing examined and 67 sand and gravel and rock samples taken. Ground penetrating radar surveys wereconducted at twelve sites to determine depths to the water table and/or bedrock.Results of the study indicate that common variety mineral materials of high quality are not abundanton the Forest. Twenty percent of the sand and gravel samples tested are suitable for use in asphalt,whereas none of the samples were found to meet the criteria for base course. All of the rock samplestaken met the criteria for asphalt and 60% met the criteria for base course.There are significant resources remaining on Forest land, especially if the material is to be used asborrow or fill. To properly exploit these resources, a pit management program is needed.
