Three constables: engineer Frederick Baddeley; land surveyor Joseph Hamel; and a man known only as Evrington, set out to explore the Gaspé Coast and discover a settlement at Heppell in 1833. In 1830, navigator Joseph Barthe described the Gaspé Coast as a thick, wild and primitive forest, that was impossible to penetrate beyond the Matapedia river.

The Gaspé Coast was a land that was impounded by Lower Canada. 1833 marked a change of events for this virtually unexplored territory. The Kempt Road is completed, and a commission is created by the Canadian government to find any unknown settlements in the region of Québec.

The three constables left Québec on September 1st, on board a schooner named La Lazy ans arrived at Grand-Métis on September 6th. The next day the groupe began their trek towards. Lake Matapedia on the new path that was created to join it with la Baie-des-Chaleurs (loosely translated as "The Bay of Warmth"). Evrington is in charge of maintaining the groups journal. He enters an inscription he finds on the border of the trail, at the end of Lake Matapedia.Written by land surveyor éric J. Fournier it reads: "Road of about 25 miles from here to Pointe-à-Snelles at Grand-Métis".

This trail had been created by Major F. Fournier and his sons in 1839, originally begun by Major A. F. Wolf in 1830. Later on Evrington notes that the two most important tributaries of the Matapedia are the Causapscol and the Kassimaquagan rivers. The name Causapscol is also used for all the and around the junction of the two rivers. Evrington's journal is the oldest known documentation of the mention of the word Causapscol, which later became Causapscal.

"We arrived at the Causapscal river at eleven thirty. We ate dinner, dried and warmed ourselves on the south side of the river (as they were travelling down stream, they were certainly on the land of the Matamajaw). Here we hid provisions that we would collect on our return from Gaspé. We covered a wax bag in birch tree bark and buried it at the foot of a ceder tree. The bag consisted of twenty pounds of lard and sixty pounds of flour. Leaving at one o'clock we began to descend the river, travelling approximately three miles
(most likely at Heppell). Here we discovered a clearing in the woods. When we called out a man appeared. We continued to descend at the rate of five or six miles an hour. At around four o'clock we came across another clearing (this was what is now known as Glen Emma) where a group of lumberjacks had established a camp. They informed us that the land was excellent but that the wood was not very good".

Once the three explorers had descended the river they set out by foot for Restigouche,
arriving there on September eleventh. Thanks to their Amerindian guides, they were able to separate to explore a vaster area of the Gaspé Coast. Records show that they explored three other rivers: The York, the Cascapédia and the Grande-Rivière. Baddeley returned to Restigouche before the his two companions, and tried in vain to hire two Amerindian in order to return to Métis. He says in his journal:
"I am unable to organize a plan to return towards the west, by way of the Causapscol road and the Matapedia river to go to Quebec (He wished to recouperate his provisions). Later the others meet up with him at the Baie-des-Chaleurs and together they travelled by schooner to Québec, arriving on November 1st, 1833.

In 1824 le chemin du Roi (the Kings Road) that follows the St. Laurent river to Métis, is completed. Several years before in 1818 the gouvernment, believing that they would be attacked by the Americans as they were in 1812, decide to explore the Matapedia valley with the possibility of creating a military road there. Land surveyor Joseph Bouchette is put in charge of the project. Another survey is done in 1824 by James Crawford but no decision is made about craeting a trail. In 1829 William McDonald and land surveyor Eric Fournier trace a ninety-eight kilometre road between Métis and Restigouche. Beginning in 1830 the construction takes two years and costs $30 000. The existing name Kempraul comes from the English name Kempt Road.
