Mount Nystrom is located in the southern portion of the Wind River Range and right on the Continental Divide. It is one of the most easily accessible 12,000 foot peaks in the entire range; with round trip hiking distances ranging from 10-14 miles. Unlike many parts of the Wind River Range, Mount Nystroms’ slopes are gentle and there are no glaciers on this mountain. Nonetheless, Mount Nystrom is a worthy destination and because of its prominence views are excellent. If you are looking to avoid crowds, Mount Nystrom is a good choice; the Sweetwater River trailhead has some of the least used trails in the range.

The route from the Sweetwater River trailhead to the summit is scenic, passing through a forest that was burnt down years ago, which is now coming back to life; to the mellow southwest ridge of Mount Nystrom with great views. An area plentiful with wildlife; many deer and elk were seen on the way to the summit.

From the summit of Mount Nystrom, you will have excellent views of the Wind River Range to the north and east. Looking north you will have good views of Temple Peak, East Temple Peak and Wind River Peak will be the three most noticeable peaks. Looking east you will see Atlantic and West Atlantic peaks, in the very southern tip of the range. On a clear day, looking west you will be able to see the “flat topped” Wyoming range about 75 miles away.

Mount Nystrom has 1816’ feet of prominence and comes in at #44 for Wyoming peaks with the most prominence. Click here for Wyoming’s top 100 peaks with the most prominence.

*Added by jimmyjay
-Nystrom was named in 1877 by F.M. Endlich (on the Hayden Survey) for his wife's family.
-Nystrom is geographically of interest because at this point the Continental Divide leaves the crest of the range, entering the Great Divide Desert while the crest of the range skews into the Sweetwater drainage.

Getting There

Passenger cars will be able to make it to the Sweetwater Guard Station, which is 2 miles from the trailhead, the next 2 miles is very rough and most people will not want to drive their cars all the way to the trailhead, however, I was able to drive my Mazda within a ½ mile from the trailhead with no problems (didn’t even scrape), the next half mile had some large rocks that even some high clearance vehicles will hit.

When To Climb

The best time to visit the peak would be mid June-September during a normal snow year. Snow on the southwest ridge will melt off rather quickly because of its direction. However, snow may linger on the summit ridge; there are several bumps which you will go over near the summit.

The southwest ridge isn’t steep enough to require ice axe or crampons (unless under icy conditions) and avalanche danger would be almost zero on this slope, it would make a good winter hike, but the approach could be much longer.

The Sweetwater campground is located by the Sweetwater Guard Station, right before the road turns rough for the last 2 miles to the trailhead. This campground is small and busy for being in such a remote location, with nightly fees.

If you are looking for primitive camping, there are many nice spots, I found a nice one up the road towards the trailhead, right before I couldn’t go any further, there was a pullout to the right which extends 50 yards from the trailhead road and ends at a camp spot right above the Sweetwater River. There are a few other primitive camping spots that exist below this one and by the trailhead there are several spots next to the river.
