Loved the dramatic picture of Curtain Falls Randy!  db is correct, it's truely easy place to recognize.  See attached picture from "The Voyaguer Highway, Grace Lee Nute, MN Hist Society, 1944 describes:

"David Thompson's journal, July 18th 1797; He "very near upset" in a strong Current' just before reaching the portage at Curtain Falls, which he descrbes as about two hundred yards in length on the right-hand side of his route.  The unloading was "very bad" and the bank was steep.  He gives the height of the falls as twenty feet.  At nine thirty he and his people encamped for the night."
