<br /> <br /> <br />1 <br />i <br /> <br /> <br />ridge that separates Dowe Flats from the town of Lyons. The <br />hogback ridge is normally a monocline formed by the uplift of the <br />Front Range, but in this area it appears as the eastern limb of a <br />doubly plunging anticline with an axis approximately located on the <br />eastern edge of the Lyons town limits. <br />On the northern side of Dowe Flats in the vicinity of Dowe <br />Pass, the regional hogback has been offset by a major northwest <br />tending high angle fault with a trace along the Little Thompson <br />River. This fault is one of the many large faults that have offset <br />the hogback. The southwest side containing Dowe Flats is the <br />downthrown block, with displacement estimated at 600 feet (Hunter <br />1997). <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />1 <br />1 <br />LJ <br />Rabbit Mountain is a large, southward plunging anticline that <br />forms the ridge east of Dowe Flats. It has a steeply dipping <br />eastern limb and a gently dipping Western limb, a structural style <br />opposite to the general trend of folding along the Front Range. In <br />addition, several smaller faults and canoe folds overprinted on <br />this anticline distort and disrupt the bedding to produce further <br />structural complexity. <br />Dowe Flats itself is underlain by a southward plunging <br />syncline. This syncline is nearly symmetrical with no significant <br />folding and faulting at the south end of Dowe Flats. Its northern <br />boundary is the extremely complex Dowe Pass area, an intensely <br />folded area containing numerous anticlines and synclines along with <br />some faulting. <br />Two faults are shown within the eastern portion of portion of <br />Dowe flats by Mailed (1962). One high angle northeast tending <br />fault is located in the northwestern quadrant of Section 15. The <br />other fault is located in the eastern half of Section 15 and trends <br />northwest. Both faults are inferred and are and are shown with <br />very small offsets. However, documentation of evidence for these <br />49 <br /> <br />
