TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the Canada Base Map from Natural Resources Canada with Toporama contours layered over it — the CanVec topographic data behind the printed NTS sheets, and the mapping used for hiking, hunting, canoe routes and back-country travel. Relief shows shaded relief and hypsometric tints. The search box finds any Canadian town, county or landmark by name, so you are not limited to La Grosse-Roche.
Reading the map like a paper NTS sheet. Click Grid to overlay the UTM grid, labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass — which matters in Canada, where declination runs from about 20 degrees west in Newfoundland to 20 degrees east in the Yukon.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a UTM/MGRS grid reference as well as plain latitude and longitude — the grid reference being what Canadian search and rescue work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.
Map search is available for a limited number of queries per session to manage costs. Be specific — search precisely for best results.

La Grosse-Roche is a hamlet in Marston; Le Granit, Quebec, Canada. It is classified as a small locality. La Grosse-Roche is located at 45.5936°N, 70.9397°W.
La Grosse-Roche stands as a singular marker upon the rugged expanse of Marston, resting near the Montagne de la Croix where the earth rises in firm, granite-strewn shoulders. It lies 5.0 km west-north-west of Lac-Mégantic, QC (from Lac-Mégantic, QC: bearing 296°T), and is situated 15.5 km south-south-west of Lac-Drolet. The land around La Grosse-Roche holds the memory of those who first cleared these slopes, moving stones to coax life from the soil while the distant Rivière Chaudière cut its own path through the lower valley. In the stillness of an afternoon, one might catch the scent of pine carried from the slopes near Lac de l'Orignal, a reminder of the quiet gravity exerted by the wilderness of Parc national du Mont-Mégantic situated further to the southeast. The local economy persists in a quiet dialogue with the geology, where the extraction of granite has long defined the character of the region, turning the very foundation of the hills into the building blocks of distant cities. Life here moves with the sun, tracing the arc of the ridges and the shifting shadows that lengthen across the fields as the day recedes into the cool, clear light of evening.
La Grosse-Roche s’élève avec une solennité minérale dans la lumière déclinante qui caresse les terres de Marston, révélant une topographie où le granit semble dicter le rythme même de l’existence. À quelques lieues de là, la silhouette de la Montagne de la Croix veille sur ce relief accidenté, tandis que les eaux de la Rivière Chaudière cheminent dans une langueur discrète à travers les vallons. La quiétude des lieux se prolonge vers les rives secrètes du Lac de l’Orignal, dont la surface argentée capte les reflets changeants d’un firmament souvent embrumé. L’horizon lointain est marqué par la présence imposante du Parc national du Mont-Mégantic, dont les cimes dessinent une frontière naturelle contre l’immensité céleste. Dans les champs environnants, le travail quotidien des hommes se plie aux exigences d’un sol généreux mais austère, héritage d’une patience paysanne qui n’a rien perdu de sa noblesse. La Grosse-Roche, par sa présence immuable, demeure le pivot silencieux d’un territoire où chaque sentier, chaque pierre et chaque courbe du terrain racontent une histoire de persévérance humaine. Ici, le vent apporte parfois un souffle frais venu des hauteurs, balayant les terres cultivées et rappelant aux habitants que leur quotidien est étroitement lié aux humeurs de cette nature souveraine.

Search Maps opens a second, independent map. It searches OpenStreetMap for any Canadian town, county or landmark by name; offers the Canada Base Map with Toporama contours and shaded relief as base layers; overlays a labelled UTM grid so the map can be read like a printed NTS sheet; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a UTM/MGRS grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
