The geosites of the Littoral

L1. Barachois de Malbaie

Location: Barachois.

Geoposition of the site: 48 ° 36 '21.0' 'N 64 ° 18' 01.0 '' O.

Accessibility: On the 132 road towards Gaspé on 10 kilometers. Point of view: easy, three hiking trails of varying lengths give access.

Unique character: Barachois.

Among the interests: The barachois of La Malbaie is unquestionably the largest wetland on the Gaspé Peninsula. With a total area of ​​1 100 hectares, it has the longest coastline in the Gaspé region (5,8 km). The latter is known for its ecological wealth: it hosts more than 200 bird species and more than 25 species of fish, many of which are in a precarious situation (CNC, 2015). In general, the Gaspésian barachois do not have more than 1 000 years (Renaud, 2000, Dionne, 2004, Quintin, 2010). This particular dynamic makes it a rich and complex environment from a geomorphological and ecological point of view.

interpretation: Guided activity.


L2. Fossilized wood

Location: Between the fishermen's haven and Coin-du-Banc beach.

Geoposition of the site: 48 ° 33 '06.0' 'N 64 ° 17' 15.5 '' O.

Accessibility: easy, by the beach of Coin-du-Banc, easy access at low tide.

Unique character: Ancient wood fossilized in the conglomerate.

Among the interests: Fossilized wood The calcined state of tree trunks is evidence of climatic aridification that was traumatic for the ecosystems of the time.

interpretation: Guided activities.


L3. Fishermen's haven

Location: Chemin-des-Pêcheurs crossing the road 132 west to 6 km from the village center.

Geoposition of the site: 48 ° 32'46.66 "N 64 ° 16'13.25" elevation 0 m.

Accessibility: easy, by the fishermen's beach, easy access at low tide.

Unique character: The youngest sedimentary rock unit in the Gaspé Peninsula.

Among the interests: Site very accessible to observe the rocks of the basin of Cannes-de-Roches near Percé. This lower Carboniferous basin includes the La Coulée, Bonaventure and Pointe Sawyer formations. There is also, above the gray coal beds of the Pointe Sawyer Formation, the red-brown sandstones of the Chemin des Pêcheurs Formation (lower to middle Serpukhovian), the youngest sedimentary rock unit in the Gaspé Peninsula. .

interpretation: Guided hike in a vehicle.


L4. The Peak of Dawn

Location: Tourist stop on the road 132 west 2 km from the village center.

Geoposition of the site: 48 ° 32'10.69 "N 64 ° 14'16.45" O elevation 127 m.

Accessibility: easy.

Unique character: Structure in bloom.

Interests for the Geopark: The peak of Aurora offers on the sea a spectacular spectacular cliff (the Wall) noticed by the geologist William Logan in 1843. This structural complexity is linked to a compressive deviation of the Perce fault. These faults are part of what is called a "flowering structure", and the vastness of the rocky outcrop of this cliff offers a rare opportunity to observe this type of structure, which is generally only observable in seismic sections.

interpretation: Guided hike in a vehicle.


L5. Cap Barre - The Three Sisters

Location: North of the Anse du Nord, located between Cape Barré and the peak of Aurora.

Geoposition of the site: 48 ° 31'53.48 "N 64 ° 12'58.91" O elevation 36 m.

Accessibility: Ideally by the sea, with boat.

Unique character: Fault hooks.

Among the interests: Rocky outcrops of the Forillon Formation (Lower Devonian), and therefore similar in composition to Percé Rock. Easier to access than the latter, it allows direct observation of this limestone franc and fossiliferous. The Three Sisters form three prominent headlands in the landscape of Percé. They are formed by large fault-type bundles (sudden curvature of the layers in contact with a fault) separated from each other by a breach of sandy fault that erodes more rapidly than limestone, hence these steep reliefs.

interpretation: Guided activity.


L6. Cape of Mont-Joli

Location: At the southern end of Anse du Nord.

Geoposition of the site: 48°31’28.50″N 64°12’18.64″O élévation 9m.

Accessibility: easy, pricing for access to the promontory. From the beach of the North Cove, view of the cape.

Unique character: Fault contact.

Among the interests: Mount Joli is physically connected to Percé Rock by a tombolo (accumulation of coarse sediments behind the rock, where the deviated waves on each side of the latter meet), however they do not belong to the same rock formation.

interpretation: Guided activity in a vehicle.


L7. Cape Cannon

Location: At the eastern end of the South Cove.

Geoposition of the site: 48°31’21.08″N 64°12’30.30″O élévation 12m.

Accessibility: Visible from the wharf and the sea. Danger of scree.

Unique character: Cambrian rocks not affected by the Taconic orogeny (collision of microcontinents).

Among the interests: Canon Head is located in the heart of Percé and consists of rocks of the Murphy Creek Formation (Upper Cambrian, 489 Ma - 501 Ma), which was not affected by the Middle Ordovician Taconic Orogeny, unlike rocks of the same age throughout the rest of the Gaspé Peninsula. That is to say, during collisions of micro-continents with the heart of the current American continent, the rocks have not been deformed.


L8. LEROY fault

Location: Beach in the heart of the village.

Geoposition of the site: 48 ° 30 '49.6' 'N 64 ° 13' 10.6 '' O.

Accessibility: Easy, sandy beach and pebbles.

Unique character: Normal fault.

Among the interests: On this site, we see that the different rock layers have been displaced by a normal fault (name given because of the direction of sliding). This displacement is visible thanks to the double line of limestone that has been separated by the fault.


L9. Cape Blanc

Location: At the southern margin of Percé, on an exit of the road 132 west.

Geoposition of the site: 48 ° 30'4.99 "N 64 ° 13'6.35" O elevation 11 m.

Accessibility: easy, 100 m trail from the lighthouse campsite.

Unique character: Double discordance - overlapping shears.

Among the interests: This majestic cape, with lighthouse and white cliffs, defines the southeastern tip of the bay of Percé. The northeastern side of the cape, at the Surprise Coast, offers the best view of Percé Rock and Bonaventure Island. On the southwestern cliff, the cap brings the White-Head (Upper Ordovician to Lower Silurian) and Cape of Hope (Middle to Upper Visean, Lower Carboniferous) formations into fault contact. A rough fault gap and a brittle training crease developed in the Cape d'Espoir formation can be observed in the coastal cliff.

interpretation: Guided hike in a vehicle.
