The lower bed, known as the Palisades coal, outcrops at water level 
near the mouth of the Hogback Canyon of Grand River, about 1' 
miles above Palisades (PL VII). Thence the coal bed rises rapidly 
above the valley and can be traced westward along the base of the 
Book Cliffs for several miles. At the Palisade mine (Xo. 6) the coal 
is about 150 feet above the valley, at the Garfield mine (Xo. 7) 800 
feet, and at the old Book Cliff mine (Xo. 9) about 1/200 feet.
