There were numerous large cracks and several slumps. All cracks observed were on the noth facing slope. <br />Large displacements and large crack widths may be attributed to the steep slopes where most cracks exist <br /> <br />New Cracks 2009 <br /> <br />site # <br />Azimuth 61312009 <br />Min Len th Max Width IN Max Displacement IN Direction of Dis lacement Photo # Notes <br />acks <br />, observed <br /> <br /> <br />ite # <br />Azimuth <br />Min Len th Max Width IN 11/1012009 & 111171 <br />Max Displacement IN Direction of Displacement 2009 <br />Photo # <br />Notes <br />1-09 <br />2-09 <br />[ 50 <br />335 >200 <br />50 36 <br />12 36 <br />24 down to the north <br />down to the east 201-203 <br />200 & 204 <br />propagates from 01-09 <br />3-09 330 >150 24 60 down to the east 205 & 206 - <br />4-09 <br />00 <br />5-09 315 <br />70 50 <br />>100 8 <br />36 9 <br />36 down to the east <br />down to the north 207 <br />208 - <br />ma bean extension of of-09 <br />06-09 209 soil separated from a large rock <br />07-09 <br />08-09 <br />09-09 <br />5 <br />330 <br /> <br />30 <br />12 <br />5 <br />6 <br />none - <br />down to the west 210 & 211 <br />212 & 213 <br />214 <br />215 hillside is slumping <br />crack runs perpend to to <br />en-echelon cracks on a historic slum 'n area <br />photo of slumping area west of 12-09 <br />10-09 <br />11-09 <br />12-09 <br />13-09 315 <br />various <br />330 <br />290 100 <br /> <br />300 <br />250 2'-12' <br /> <br />9 <br />48 1 <br />none <br />none <br />none down to the north 216 & 217 <br />218 <br />219 <br />220 cracks in sandstone outcrop - perpendicular cracks are smaller <br />cracks and slumping <br />crack in oaks <br />la a crack>10' dee <br />14-09 310 170 4 none - 223 - <br />15-09 <br />16-09 <br />17-09 60 <br />70 <br />90 >50 <br />>100 <br />40 24 <br />8 <br />3 72 <br />none <br />none down to the north <br />- 224 & 225 <br />226 & 227 <br />228 large crack - art of 13-09? <br />crack and rock fall on a steep slope <br />small cracks <br /> <br /> <br /> <br /> <br />•
