Sepulcher Mountain Trail Description (1K3) - Moderate Traffic

Compared to the other peaks in the Gallatin Range it's easy to overlook this nondescript mountain at the northern edge of the park, but don't be fooled by appearances, Sepulcher Mountain has some of the best views in Yellowstone.

From the Glen Creek Trailhead the trail heads northwest for 1.8 miles along the Fawn Pass Trail over fields of sagebrush mixed with a wide variety of unique and colorful wildflowers. As the trail crosses the open expanse of Gardners Hole, expect extraordinary views of Electric Peak, the Gallatin Range and of course Sepulcher Mountain. The first 1.8 miles is an easy walk all the way to the Fawn and Snow Pass junctions where you can choose a few alternate hikes (see below). We've seen bighorn sheep on the slopes of Terrace Mountain which is on your right as you walk the first few miles of the Glen Creek Trail. Bison, elk and grizzly bears are also common in this area as well.

After reaching the Snow Pass Junction the trail continues toward Sepulcher Mountain climbing through a small notch on the Sportsman Lake Trail. You'll begin gaining a little elevation as the trail climbs this narrow section to the junction with the Sepulcher Mountain Trail. Glen Creek will be on your left as you work your way up this easy grade. Moose often frequent this area so be on the lookout and you may catch a glimpse of these solitary animals grazing in the wetlands that border this small creek.

At 2.5 miles the Sepulcher Mountain Trail enters from the right and the steady climb to the summit begins. It's another 2.5 miles to the top of Sepulcher from this location but there are plenty of great views to soak up as you begin zigzagging your way to the top on a beautiful open hillside. Electric Peak will be visible to the left and the peaks of the Gallatin Range stretch to the southern horizon.

Just before reaching the summit the trail enters a wooded section for the last 0.4 miles as you make your way up the final ridge to the top of Sepulcher. Upon reaching the summit the best views are to the north and northeast with Electric Peak standing at 10,928 feet just across the valley. The massive Absaroka Beartooth Wilderness is visible to the northeast and the pyramid shaped summit of Emigrant Peak can be seen overshadowing the distant hills.

From the summit you'll begin descending the northeast side of Sepulcher to a beautiful rocky point that lies about 0.4 miles further along this loop. At this overlook there are a number of dramatic vantage points that look down on the town of Gardiner and the Yellowstone River as it exits the park and makes its way through the beautiful valley below. If you hike Sepulcher as an out and back make sure you visit this overlook as well before you begin your descent back to the Glen Creek Trailhead. It's well worth the extra 0.8 of a mile it takes to reach the overlook at this craggy point.

If you continue this hike as a loop you'll double back toward Sepulcher briefly before connecting once again with the main trail which begins descending on the left. You'll follow the edge of a cliff for a short distance through gnarled and broken trees as the trail drops steeply toward the junction with the Clagett Butte Trail. Over the next 3.2 miles the hike passes through a dense stand of pines, open hillsides and large areas that contain extensive deadfall. At 7.8 miles there is a great view of Mammoth Hot Springs set against the barren hillside of Mount Everts. The trail continues downhill, twisting and turning toward its lowest point at the junction with the Clagett Butte Trail at around 9 miles. Heading right you'll begin ascending again through a pine forest that offers a brief bit of shade until it reaches a flat meadow at 9.3 miles. The Trans Line cuts through this field and will be visible intermittently for the remainder of the hike. On the opposite side of this meadow the trail drops yet again to meet the junction with Snow Pass before climbing a short steep section over the pass. NOTE: During the winter this is a very popular ski trail that starts at the parking lot located at the Upper Terraces.

After climbing over Snow Pass the remainder of the hike covers gently rolling terrain until you reach the junction with the Fawn Pass Trail. Turn left and it's now an easy 1.8 mile trip back to the Glen Creek Trailhead as you cross the open terrain of Gardners Hole one last time.

ALTERNATE HIKES:
The Fawn Pass Trail will take you to four beautiful campsites (one is stock only) along the Gardner River and eventually all the way to Fawn Pass. A great hike if you want a really long day hike (10.3 miles one-way to the top of the pass).

You can take the Snow Pass Trail toward Mammoth Hot Springs (downhill) and then ascend back up through the Hoodoos, past Golden Gate and back to the Glen Creek Trailhead for a nice 6.3 mile loop.

Tip: Try to to arrive at the trailhead early if you plan to hike Sepulcher Mountain. This can be a busy area and the parking lot can fill quickly.

WARNING: The weather in Yellowstone can change rapidly at any time of the year. During the summer months afternoon thunderstorms are very common and there is no quick way down from the summit of Bunsen Peak if the weather turns bad. Temperatures can drop significantly within minutes and at elevation the wind will almost always be a factor even on the nicest of days. Start your hike early and be off the mountain by mid afternoon.
