St. Mary Peak
Stevensville, Montana
St. Mary's Peak in late fall
Father Pierre Jean De Smet, S. J., together with his fellow Jesuit Missionaries, Fathers Gregory Mengarini and Nicolas Pointe and three Lay Brothers first entered the Bitterroot Valley on September 24, 1841. The wagon and three carts holding their supplies were the first "vehicles" to enter the area.  They established the first white settlement in what was to become Montana, on the east bank of the Bitterroot river, immediately west of the present town of Stevensville.  The new mission, as well as the river and the tallest mountain peak to the west, were named "St. Mary's".  Fifty years later the name of the river was changed to "Bitterroot" by the Forest Service after the prevalent Bitterroot plant.

St. Mary Peak rises 9300 feet above sea level and over 6000 feet above the valley floor. At its pinnacle is a fire lookout station that offers breathtaking views for miles around. The 4.5 mile hiking trail is considered moderate in difficulty, although there is a 2400' gain from the parking area to the top.

The Salish considered the Peak to be sacred and was a place for a Vision Quest.  Today,  hundreds of hikers visit each summer to view the timeless scene of the Bitterroot Valley first witnessed by the Catholic Missionaries.
