River Description
The West Rosebud is usually divided into two distinct sections by local paddlers. The short but fun Upper run is about two and a half miles long and contains almost continuous whitewater. The longer Lower run is more than 10 miles long, with most of that distance in a wilderness setting. Although this lower stretch begins with the two most difficult rapids on the river and ends with a mile of fun Class IV, it has long sections of scenic flat water. In combination, the West Rosebud offers a unique opportunity for a full range of creeking conditions during warm summer days.
The put-in for the Upper run is easy and beautiful--just slide into Emerald Lake and enjoy the spectacular view of the still snow-covered peaks of the Beartooth Mountains while the slowest member of the party is still struggling with boating gear. The West Rosebud ramps down quickly from the outlet of Emerald Lake. The first half-mile of the run drops at an average rate of about 150 fpm through two rapids. The first rapid, Spillway, tends to be rocky at almost any level as the river widens and sweeps around a right turn visible from the road on the way to the put-in. A big eddy on the left turn near the bottom of the rapid also marks the beginning of the more difficult second rapid, Triple Tongue. At higher water levels, this rapid can become pushy.
After a half mile of fast and increasingly interesting water, the river enters the second steep section. This stretch, over a mile long, contains the best rapids on the Upper run. The first horizon line leads to an island and marks Snake, where the line is usually down the left channel. The hardest rapid on this run, Stump, is also marked by a horizon line and deserves a scout the first time down. At higher water levels (above 2.5 on the bridge gage), this rapid is a class V with three large, offset holes. Snag is not far below, again marked by an island, and usually run down the narrower right channel. Finally, Goat Boy is a long rapid w

Trip Reports
Log in to add a reportI would disagree with this comment... just ran it yesterday at similar flows. Info listed in the river description is accurate. Drops are worth scouting... if you have never seen/run them. Goat Boy has a pin spot on river left that unscouted is not good. If you go with someone that knows the river well, then I could see not having to scout. Boogie though is an under statement. I would give it IV+/V- at flows above 600 cfs... it would be a mistake to go into this run thinking you were getting a simple class IV boogie.
We paddled this in June 2002 at 660cfs. We put in on Emerald Lk. and took out at Pine Grove Campground. The average gradient is near 150fpm with the beginning a little bit steeper. There are no significant individual drops, just 2.something miles of non-stop class III-IV boogie water. The water quality was beautiful when we were there, and the scenery at the put-in was great. It's in the guidebook, 'Montana Surf'.
