sandstone intervening between the typical Eden shales and overlying 

 San Timoteo. A similar indurated sandstone may be seen both a quar- 

 ter of a mile to the south, capping an end of one of the typically low- 

 lying blue ridges, and again above the blue Eden shales in the Rabbit 

 Grade cut. The aspect of unconformity between the two San Timoteo 

 formations has been generally heightened by faulting. The normal 

 southwest dip of the southern limb occurs with certain interruptions 

 throughout the area to the west and south of the mountain. The 

 most noticeable interruption to this even trend away from the moun- 

 tain schists is along the short northeast- and southwest-dipping fold 

 occurring a sixth of a mile to the mountain 's south. The same fold is 

 limited eastward by a projecting spur of the mountain metamorphics. 

 Beyond the spur sedimentary deposits again occur, here lying steeply 

 inclined toward mounds of the complex, which have been faulted down. 

 These mounds are separated from the monadnoek by a small intervening 

 valley. Eden-like deposits also extend over the central and south- 

 western portions of the mountain proper. An especially fine series 

 of finely laminated beds lines the sides of an interesting and peculiar 

 little valley that has been worn deep into the metamorphic limestone 

 of the upper area. 



The topography of the Badlands in the Eden locality differs from 

 that farther west in the east and west versus north and south align- 

 ment of its caiions and ridges, through the Eden mountain mass 

 having so far acted as an effective l:iar to southward erosion. From 

 the north a view of the Eden region shows a long reach of brush 

 grown slopes and ridges, and a tumbled brush-grown upland. From 

 the south the view is of a schistose wall rising in rocky skyline from 

 a low table land of sedimentary hillocks. 



The denuded Eden scarp and the broken strata immediately to its 

 south suggest a continuance near the mountain and valley inter- 

 section of the fault line, marked a short distance to the east in the 

 high hanging and slicken-sided face of Claremont. The continuity 

 of the same fault line westward is moreover suggested by the long 

 line of springs in Reche Caiion and the steepness of the strata of the 

 Moreno-San Timoteo edge.
