Both have secondary <br />accumulations of carbonates. Bowbac occurs over soft weathered shales, siltstones and sandstones. Bowdish occurs over hard <br />Sandstone <br />MAP UNIT: 98E - Darvey - Barx complex, 0 to 3 percent slopes <br />MAP UNIT: 98E - Darvey - Barx complex, 0 to 3 percent slopes <br />(Revised June 2008) Attachment 2.04.9-9-5
