The Leonard facies in the Denver hills consists of a series of ls tongues which tend to become thinner to the S.W. and break up into a number of thin units by additional shale tongues. The structural problems are big especially in the area south of Sullivan Pass, between Durgout Mts. and the Altada Ridge. Of course it is all covered but there is still a real problem to figure out. Kings map is wonderful, but he isnt very consistent about his boundary between the Word and Capitan - his Leonard + Word also have problems - the carbonate sed which he places in the Leonard in the west is about the right height for his 1st Wnd limestone in the east. I.E. It seems the Word Leonard boundary is also inconsistent. The base of the Wnd in the west seems to be about the 3rd ls. of the central Mts. In Section 12 his unit is greatly thinned and may represent the key between the Lockney facies to the east and the bas to the west.
