PTGE meaning in General ?

Portage or portaging (Canada: ; US: ) is the practice of carrying water craft or cargo over land, either around an obstacle in a river, or between two bodies of water. A path where items are regularly carried between bodies of water is also called a portage. The term comes from French, where porter means "to carry," as in "portable". In Canada, the term "carrying-place" was sometimes used.

Early French explorers in New France and French Louisiana encountered many rapids and cascades. The Native Americans carried their canoes over land to avoid river obstacles.

Over time, important portages were sometimes provided with canals with locks, and even portage railways. Primitive portaging generally involves carrying the vessel and its contents across the portage in multiple trips. Small canoes can be portaged by carrying them inverted over one's shoulders and the center strut may be designed in the style of a yoke to facilitate this. Historically, voyageurs often employed tump lines on their heads to carry loads on their backs.

Portages can be many kilometers in length, such as the 19-kilometre (12 mi) Methye Portage and the 8.5-mile (13.7 km) Grand Portage (both in North America) often covering hilly or difficult terrain. Some portages involve very little elevation change, such as the very short Mavis Grind in Shetland, which crosses an isthmus.
