161 August 17. Hawkes Bay, north Shore. The crest projects in about 200 yards northwest along the crust upon more eastward and fairly tumbled dolomite dipping 15°N. 70W. The dip steepens to vertical in the next 200 yards and the strata in along the edge of a little core about ½ mile SSW. of the Whale Factory. At about 200 yards to the west side of this core where the rocks are again upturned, here the dolomite is in beds 2 to 6 inches thick and one layer shows small sun-cracking. The dip is 8 N. 45°W. Out-dip of beds 176-177°. At about 200 yards further the strata dip 5 S. 40 E. Here they are light dove colored dolomite in heavy beds interbedded with fintle, red and chalky beds. This is near the whale factory, and the exposure continues to the same and for about ½ nautical league. At about ¼ mile or a little less further the dip undulates from northward to southeast. The beds are light dove colored dolomite in fairly heavy beds some of which are durmerically and full of Cryptozoon. Many of the layers are sun-cracked. A few feet below the Cryptozoon, are thin bedded chalky layers full of ripple marks and sun-cracks. Below there are 3 feet of birdlike fine grained sandstone like the lower part of the Buckmantown near near Port an Port. Beyond this the strata abruptly bend up to a dip probably due to a fault which is focussed by loose material. It is probably a very small fault since similar small sandstones occur just beyond this line, and below about 8 feet of this comes once thin bedded chalky and much sun-cracked beds in 2 feet alternating with
