Perce', Quebec, August 6 1929, Tuesday Started our tope 8A.M. tr investigate the Priests road tr locate on Clarke's Map of 1917 the various geological formations, and tr take dips and strikes. Crossing the front - Tron au chat - one soon saw that all of Clarke's Hog is Ordovician like Perce' Rock. It stands very vertical = dip 75° S-E, strike N.85° W, and is cut by pink orthal. jdg mns near at right angles to the strike. Where the Ordovian comes to the Priests road the dip is 70° S.E. and strike N. 70° W. This strike leads into Tron au Chat puleh where the Ordovician is outcrop by the Bonarentine. The Ordovician or the road crosses a wide gneis. In the gutter saw a little fluctuated Ord. outcrop. Then follows the Bonarentine crop, about as Clarke has it, only it appears to be continuous with the Bonarentine of the Pic d'auron and in the criele. It appears to lie nearly horizontal, and mostly the pettles are of the Ordovician. At the Grand Coupe the Bonarentine trace of St. Anne comes down all the way to the stream. here crossing the road and even below. How the strata appear to be horizontal all the way to the top. At the mouth of this brook in the Richmondian and I judge it comes up all the crees, and is outcrop by the Bon- arentine and notes Clarke has it north a litt of the Heldetley in 2 morg; his notes should come up to enclose by the Bonar.
