Gascons Formation 
Logan described this long series of muddy, fine-grained sandstones 
under the numbers 3 to 7 of his sections in “ Geology of Canada”, giving 
them a thickness of 1,750 feet. The formation may be seen from Anse-^-la- 
Barbe and Gascons east to Anse-^-la-Yieille, and in scattering places back 
in the land. Throughout, the strata are marked by gastropod trails and 
especially by the worm-burrows known as cauda-galli or Taonurus . There 
are also scattering corals which are most common toward the top of the 
formation, or east of Chouinard brook. About Anse-&-la-Barbe the top 
of the Gascons formation is exposed and some fine cephalopods were 
collected (Phragmoceras, Cyrtoceras, Orthoceras, and Gomphoceras subgracile). 
On the west side of McGinnis cove is a fine exposure of the Bouleaux 
formation. It passes downward into the Gascons formation, but of this 
little is to be seen, since all the low land here is covered by fill detritus 
accumulated when the sea-level stood higher than it does now. The Gascons 
formation underlies all the lower land of this cove, and to the southeast 
is in fault relation against the lower pink limestone of the West Point 
formation. 
Another fine exposure of the Gascons formation is all along the sea- 
shore of Port Daniel Centre and outward toward West point. Here nearly 
everywhere it weathers red, but within, the strata are green. One descends 
in the strata of the syncline going northeast from West point toward little 
Ruisseau Castilloux, but long before reaching it the lower strata of this 
formation are marked by a zone 35 feet thick of thin-bedded limestones 
which are repeated along the beach in one minor and one prominent 
compound anticline. Then there is a zone with Monograptus that further 
helps to fix the structure and thickness. All the strata are closely appressed 
and as a rule stand nearly vertical. Other than Taonurus and gastropod 
trails, fossils are scarce. 
More of the detail of these strata will now be given, descending in 
the synclinal series, but it should be stated that there is no break in the 
sedimentation at either end of the Gascons sandstones; the boundaries 
are arbitrarily drawn and mainly on the basis of the lithology.

Bouleaux formation above 
Red-weathering, muddy, very fine-grained sandstone exposed in a small 
cove a little east of the home of John Beebe, less than one-half mile north 
of West Point light. Dip 50 degrees south 10 degrees west 170 
Same kind of strata replete with Taonurus burrows from cove point to cliff 
ladder up to second house, and on northwestward to another little cove 
point. Dip varying from 60 degrees to 40 degrees toward the south. 
Occasional Orthoceras are seen 300 
Same strata with Taonurus to a place where the beds are much twisted. 
Strike of strata and beach nearly alike. Average dip about 40 degrees 
toward the southeast 145 
Area of twisted and sheared strata, due either to a small anticline or a turn 
in the strike. Thickness unknown but estimated at 100 
Red-weathering, muddy sandstones, as before with Taonurus . Dip 70 
degrees south 10 degrees west 380 
Monograptus cf. clintonensis zone to waterfall 100 
Muddy sandstone as before, but west of brook 175 
A closed and faulted anticline consisting of thin-bedded, blue, impure, and 
unfossiliferous limestones, alternating with shales, on either side of a 
central sandstone bounded by slip faults cutting out about 16 feet of 
strata. Strata about vertical. Here 34 feet thick, but should be 60
