Clarification The first time I tried to reconcile this article with GoogleEarth imagery I thought the article had serious errors But then I realized there are 2 Mount Jefferson s in Montana and the one this article refers to is the SOUTHERN one near the Idaho Wyoming corners I also found at least 2 other creeks with similar or identical names the most prominent one being 160 km 100mi ENE near Red Lodge MT which has a road lake named for it I don t know how to clarify the article without introducing original research but it needs to be fixed The coordiates which I initially overlooked appear to be reasonably accurate but not conspicuous enough within the article
