In the spring of '98 on a warm clear day after the roads opened up in the B-root we drove up to St. Mary's TH and hiked up the peak. Ate some lunch at the summit, then skiied down the middle of the huge bowl behind St. Mary's across a partially frozen tairn. Continuing north into the Kootenai drainage we found natural half pipe for another 1000' vert. Finally, after some sketchy turns on wet snow on rock we began a heinous down shwack to the creek. About 3500' of hero corn in all. After an extreme log crossing across a roaring creek with tele boots on we hiked out the canyon past the sport routes to a stashed truck.
One of the best days of many I had in the B-root.
