EXHIBIT B - SITE DESCRIPTION <br />1. Location and General Land Use Information <br />The Yule Quarry is located south of Marble, CO a distance of 2.6 miles. <br />The additional affected land (-2.3 acres) to be encompassed in this amendment is located in the <br />following: <br />• Two patented federal mining claims, one lode and one placer <br />• 0.919 acres in the Historic Mill Site leased from the Town of Marble <br />The location of the lands to be added at the quarry site is shown on Maps C-2 and C-3. <br />Prior to disturbance, the area consisted of high mountain forest on steep slopes at an elevation of 9300 <br />feet. Most of the current estimated disturbed area of 3.6 acres at the mine was historically disturbed well <br />before the initiation of reclamation laws in 1977. <br />2. Site Geology <br />The marble at Yule Quarry is an exceptionally high quality (>99% calcite) metamorphic deposit of the <br />Leadville Limestone of the Mississippi Age. Formed by contact metamorphism during the Tertiary <br />period, it occurs as a massive bed (>200 feet thick) that outcrops along the Yule Creek. The marble <br />formation is located below the Pennsylvanian Molas Formation and above the Dyer Dolomite Member. i <br />3. Hydrology <br />The affected area drains exclusively into Yule Creek through a small tributary located as shown on Map <br />C-2. This tributary is an ephemeral stream that only flows during spring snowmelt and summer <br />thundershowers. Its drainage area is less than 10 acres. Yule Creek joins the Crystal River near the town <br />of Marble approximately 2.5 miles north of the quarry. The closest standing water is located at beaver <br />ponds approximately 1 mile north of the quarry. In the area near the quarry, Yule Creek is a rapidly <br />' Colorado Yule Marble - Building Stone of the Lincoln Memorial U.S. Geological Survey Bulletin #2162, c.1998 <br />Yule Quarry April 10 7
