Hot topic of the news, the erosion is caused mainly by natural processes. In the spring, its effects are monitored with a magnifying glass, especially in the coastal region. At the UNESCO Global Geopark in Percé, this phenomenon is visible everywhere in the territory.
Various warnings are given to hikers every year, since the risks are real. In this article, we understand that nature is not the only person responsible: erosion can also be accentuated by human interventions.
First, here are some examples of erosion causes:
- The action of the waves
- The wind
- Alternating periods of freezing and thawing
- Coastal storms
- Denudation of surfaces
- Structures hindering the natural circulation of sediments on the coast
The action of the waves
In Percé, it's a phenomenon that we know well. The repeated action of the waves, especially during high tides and strong storms, has the effect of digging the beaches and the base of the cliffs, in addition to moving the sediments offshore. The notches created at the base of the cliffs can lead to rock collapses or landslides.
The wind is also an important factor in Percé. Strong winds that blow on sandy beaches for long periods carry large amounts of sand. They can even cause the displacement of certain beaches. In the mountains, it is not uncommon for the wind to drop trees rooted in the cliffs, taking with them part of the soil.
Alternating periods of freezing and thawing
Under the effect of freezing, the water contained in the porous sedimentary rocks and in their cracks expands from the liquid phase to the solid phase. This expansion is likely to cause the fragmentation of the rocks and their detachment from the cliffs.
That's why there are several posters at the Geopark that show you the danger zones. The geosite of the cave is a good example. Each spring, rocks and vegetation are detached from the walls. It is the same for cliffs at the seaside.
In clay zones, the alternation of periods of freezing and thawing can also cause mudslides. This phenomenon can be seen in some caps of red soil at Percé, as at the geosite of Le Havre des pêcheurs.
Wave breaking during coastal storms is a major cause of erosion on the shoreline. The people of Percé know something about it. These waves are particularly devastating during a "storm surge", this severe meteorological depression combined with a high tide and powerful winds pushing the sea towards the coast.
During these events, the sea level becomes abnormally high, generating a temporary flood of the coastal zone (marine submersion). These storms accelerate the erosion of seaside lands and beaches.
Denudation of surfaces
Degradation or destruction of vegetative cover in coastal areas caused by deforestation, vehicular traffic or hiker trampling weakens erosion resistance.
At the seaside, the sediments thus laid bare are more likely to be transported. In addition, the runoff is amplified which favors gullying. In the mountains, mud is a problem.
That's why at the Percé Geopark, visitors are encouraged to stay on marked trails and avoid dirt roads in motor vehicles or off-road vehicles.
Structures hindering the natural circulation of sediments on the coast
The development of a large number of structures on the coastline is an important cause of erosion. Even erosion protection works can sometimes magnify the problem rather than solve it if they are poorly designed, poorly maintained or installed in inappropriate locations.
Rocks and retaining walls are likely to displace and accelerate the problem of erosion on neighboring lands (end effect) or on the beaches in front of the structure.
In Percé, the wall that was installed in the 80 years to support the seaside pedestrian promenade in South Cove, was finally washed away by the sea, after causing heavy damage in the center of the town.
In 2018, thanks to an ambitious beach refilling project whose mission is to protect Percé from erosion, we have been able to solve the problem and give Anse-du-Sud its old-fashioned airs, with the added bonus of pebble beach.

PERCÉ GEOPARC BECOMES UNESCO WORLD GEOPARK
Percé, 17 April 2018 - The Canadian Commission for UNESCO and the Géoparc de Percé are pleased to announce that the latter has just received the prestigious UNESCO Global Geopark label. This label recognizes sites that, like Percé and its magnificent Rock, bear witness to an exceptional geological heritage of international importance. The city of Percé hosts on its territory the first UNESCO World Geopark in Quebec and the third in Canada. The official request for this designation had been filed by the Gaspé organization in 2016.
"We are proud to welcome a new member to our Canadian Network, which already has two UNESCO Global Geoparks, Stonehammer, New Brunswick, and Tumbler Ridge, British Columbia. Spectacular witnesses to the diversity of our natural heritage, Geoparks play a vital role in ensuring the preservation, enhancement and sustainable development of areas of unique geological character. Through their educational mission, the Geoparks ensure an intergenerational transmission of knowledge related to the geological history and heritage of the territory. - Christina Cameron, President, Canadian Commission for UNESCO.
"The organization of the Perce Geopark is honored to receive this designation and to become part of the UNESCO Global Geoparks network. We welcome the news with the desire to share it with the whole community. We want 2018 to further develop the education component, while continuing to promote local sustainable development. - Renaud Camirand, General Manager, Géoparc de Percé.
"It is truly a great honor for Percé to be part of the UNESCO Global Geoparks Network. This prestigious label confirms that the site presents a geological heritage of international interest. I am sure he will make sure that the whole community puts his shoulder to the wheel so that this new status can be proudly displayed. The desire of the Geopark to continue to develop thematic partnerships in the coming years, with different players from Grand Percé, seems very promising for the future. - Cathy Poirier, outgoing president of the Geopark and mayor of Percé.
The UNESCO Global Geopark in Percé is located at the eastern end of the Gaspé Peninsula, in eastern Quebec. Located in the heart of the Appalachians, this great orogenic chain that covers the Atlantic side of the North American continent, Percé witnessed the birth of geology in Canada. It is in this region that Sir William Logan, the first director of the Geological Survey of Canada, began geological mapping of Canada.
The UNESCO Global Geopark of Percé, while committing to protect its territory, wishes to educate and educate visitors about the environment. The territory has a rich historical, geological and cultural heritage: historic buildings, a large network of hiking trails, various sites of geological interest including Percé Rock and Bonaventure Island.
Many artists and artisans actively contribute to the region's reputation and vitality. Located on the traditional territory of the Mi'gmaq people, Percé has witnessed a large part of its history. The Geopark strives to showcase this rich history through its activities and attractions.
The community of Percé is extremely involved in the Geopark, which was born of a local initiative through which local business people have invested in a solidarity cooperative. It is therefore with shared pride and a beautiful vision of the future that the Géoparc de Percé receives the UNESCO Global Geopark label.

STRONG ACHALANDING IN PERCÉ GEOPARC
AN AFFLUENCE THAT REVERSES THE FORECAST
Percé, 3 august 2017 - The Percé Geopark knows a much higher traffic than could have been imagined since the very beginning of the tourist season. For the first 10 days of the construction holiday only, there are 6 times more customers than 2016. The 1er last August, the Geopark had already welcomed more than twice as many visitors as for the whole year 2016.
"We had been confident in our forecasts, since two major attractions (the suspended glass platform and the zip line) were added to the overall offer of the Geopark. But even in our wildest hopes, we would not have imagined such a large traffic, "explains the president of the board of directors of the Geopark, Cathy Poirier.
Measures have been put in place to maintain a quality service for the flow of tourists wishing to take advantage of the attractions of the Geopark: hiring additional staff, extending the opening hours, opening an overflow parking, adding a second shuttle, additional display at the reception and an information booth outside the pavilion.
In this wave of popularity of the Geopark, the team does not neglect any effort to meet the demand. Highlighting the extraordinary work of the Geopark employees, who first and foremost prioritize the safety of all, Ms. Poirier approaches the second half of the season with great optimism: "We are having a memorable season. We sincerely thank the people who visit us and make the success of the Geopark. We understand that some irritants such as wait times can be sometimes uncomfortable for some, but rest assured that we work tirelessly to provide the best possible service to as many people as possible! Concludes the president.

The Geopark of Percé launches its summer season 2017 under the sign of the novelty
The Geopark of Percé launches its summer season 2017 under the sign of the novelty
Percé, 23 juin 2017 - The Géoparc of Percé inaugurates the 23 June the 2017 summer season under the sign of the novelty. First, let's emphasize that it's in the evening (at 21h30) that a brand new outdoor multimedia projection, developed during the last year by the Geopark, will be unveiled in collaboration with the Micmac Nation of Gespeg. The designer of Tektonik, XYZ Cultural Technology, realized this magnificent transposition of the Micmac Creation Legend of the world. The free screening entitled "It's 21 hours in Percé" tells the story of Glouskap, the very first Micmac.
"The Micmac Nation of Gespeg, which I proudly represent, is honored to join in the success of this collaborative project that we celebrate together today, which confirms that when Aboriginal and non-Aboriginal communities join forces, we are able to accomplish great and beautiful things, "said the head of the Gespeg Micmac Nation, Manon Jeannotte.
The evening of 23 June will also be the unveiling of the commemorative plaque of the founding members of the Geopark of Percé. Installed in the reception area of the Experiential Pavilion, it symbolizes the foolproof will of a group of Perce business people who dared to dream of a great unifying project. It is set up prominently so that we can remember that it is thanks to the unwavering support of local businesses and organizations that the cooperative has successfully completed the Geopark project.
In addition, the unveiling of a spectacular work of art on the site of the Experiential Pavilion will allow visitors to (re) discover the artist Ludovic Boney, Lévis. The contemplative aspect of the work entitled "A glitch, an apple, a culture" is against the current of contemporary frenzy. It is part of a reflection where time can be perceived at the rate of nature, that is to say, slow, calm and transcendent.
A new historical interpretation trail is also featured at the Geopark this year. Twelve interpretive panels tell anecdotes and facts that have marked the course of the village's history. For example, we learn that summer 68 in the summer 70, Plume Latraverse played at Percé at Georges and Denise Caron. He frequented with his band of "Bad companions" the bar The fisherman's hold of the Hotel-Motel Manoir Percé. His song "Gaspoésie" was born from this time.
Burst: The shuttle Geopark is in operation as of June 23. It allows the transport of people to the site of the suspended glass platform from 9h to 18h. Towards the end of July, the zip line will also be open to the public: chills guaranteed on 230 meters. On the campsite, a new service building has been installed for more comfort. This building will delight campers 4 seasons. Finally, the Caisse Desjardins du Littoral Gaspésien announced the financial support of 50 000 $.
DATE: 23 JUNE 2016 - from 19h30 to 21h30
LOCATION: PERCÉ GEOPARC EXPERIENCE PAVILION - 180, WEST 132 ROAD, PIERCED
