upriver

The stream becomes shallower as you move upriver.

During the 1800’s, keelboats were used for both upriver and downriver navigation, propelled using either oars or poles, while flatboats could only go downriver.

I read the article "The Emergence of Determiner Clisis in Upriver Halkomelem."

If First Nations interest you, maybe read the article "An Upriver Halkomelem Mink Story: Ethnopoetics and Discourse Analysis."

There's a bridge about a kilometer upriver.

According to the map, there should be a bridge about three miles upriver.
