• 52+30 to 57+7o Primarily fill on colluvial <br />materials; crosses three minor <br />drainages. Any minor cuts will <br />be in colluvium. <br />57+70 to 60+60 Cuts may be into primarily <br />weathered sandstone. Dip of <br />sandstone to east at probably <br /><7°. Cut slopes as shallow as <br />3:1 can be steepened to as much <br />as 1.5:1 to 1:1 to reduce <br />erosion. <br />60+60 to 62+70 Fill at head of drainage; <br />probably will not need a culvert. <br />62+70 to 64+80 Shallow cut; probably all in <br />colluvium. <br />64+80 to 71+00 Shallow cuts and minor fills, all <br />on or in colluvium. <br />71+00 to 79+30 Shallow fill in alluvial valley <br />eroded by tributary of Scotchmans <br />Gulch; culvert needed. <br />• 79+30 to 85+20 Cut through ridge; TH-4 on <br />alignment on crest of ridge. <br />Based on TH-4 log, cut should <br />encounter claystone to road grade <br />and possibly below. Cut slopes <br />of ~3:1 could be steepened to <br />1.5:1 to 1:1 to reduce erosion. <br />85+20 to 98+00 Major fill; crosses large <br />drainage basin of Scotchmans <br />Gulch; will require a culvert. <br />From ~90+0o to 110+00 alignment <br />is along what may be crest of <br />Fish Creek anticline; however, <br />this should not present any <br />adverse conditions. <br />98+00 to 106+70 Major cut with TH-5 at deepest <br />part. Test hole shows almost all <br />of cut to be in claystone. <br />Strong likelihood that sandstone <br />will be encountered in cut; <br />bedrock should dip 3°-10° W; <br />assume an average of about 7°. <br />Cut slopes of 2.5:1 to 3:1 could <br />be steepened to 1.5:1 to 1:1 to <br />• reduce erosion. <br />21 <br />
