| Deposit | THE LATERITE-SOFT SERPENTINE DEPOSIT COVERS THE CREST OF THE RIDGE, RANGING FROM 250 FEET TO 2,500 IN WIDTH AND AVERAGING ABOUT 1,000. THE DEPOSIT IS VERY IRREGULAR IN TOPOGRAPHY AND OUTLINE AND HAS BEEN CUT OFF ABRUPTLY BY EROSION NEAR THE TOPS OF THE STEEP SLOPES OF THE RIDGE. THE UNDERLYING UNALTERED SERPENTINE OUTCROPS DOWN THE SIDES OF THE RIDGE TO ITS CONTACT WITH THE YOUNGER CRETACEOUS ROCKS. |
