The name of the river comes from the abundance of cow-parsnip (Heracleum lanatum) growing on its banks.” <(a title="Wikipedia" href="https://en.wikipedia.org/wiki/John_Macoun">John Macoun, quoted in the report of N.B. Gauvreau, CE, 1891).
R.M. Patterson mentions the “almost tropical growth of the giant cow parsnip from which the river gets is name.” He found this growing up to 7-feet high and says “the din of the rain on the huge leaves was like the rush of a tremendous wind”.
This plant is sometimes called “Indian Rhubarb” since the native Americans eat the petioles or leaf-stalks.
