Box 478 Farmington, N. M. BT499 Per your request for data concerning soils, present vegetation densities, and reclamation the following information is provided for submission to the Colorado State Mined Land Reclamation Board. It is your stated plan to remove gravel from the open pit site, level with regard to drainage after gravel extraction, and the area left as a building site for a hay barn, equipment storage and livestock feeding area. Therefore, revegetation information is not provided. It is our recommendation, however, that the east and south sides of the pit be graded no steeper than a 2:1 slope to prevent soil and bank sloughing. Also, topsoil removal from the site has not been addressed. It is the stated plan to not re topsoil the area. The topsoil in this area will range from several inches to 5' in depth. Placement of this overburden material must be decided upon. If it is not wanted on the immediate site, hauling of the Overburden to low lying areas is advantageous. A soils boundary map and descriptions of the three present soil types is provided for your use. Present vegetation on the site is as follows: Big sagebrush 30% Western Wheatgrass 20 Indian ricegrass 5 Blue grama 5 Muttongrass 5 Junegrass 5 Needle & thread 5 Total annual production of air dry Pinyon Pine 2 forage = 650# Rocky Mt.
