Arc Dome

hike | 2024-06-23

Arc Dome was on my to-do list last November, but too much snow and limited time got in the way. This time, I was determined to tackle it and add another ultra-prominent peak to my list. After finally hiking Arc Dome, I can say it’s a fantastic trek with lots of open space and stunning views. The wide landscapes and the feeling of solitude made the hike memorable, proving it was worth every effort.

When I saw the temporary slippery road sign, I didn’t get it at first; later, I spotted millions of crickets covering the road.
The walk starts in the lovely leafy forest.

At the trailhead, I unexpectedly ran into two other peakbaggers, Iris Ma and Tom Grundy. Even though we didn’t know each other, it was amusing to find out we shared the same hobby. They had already hiked to the summit the day before and were now packing up, getting ready to leave. It’s always interesting to see how small the world can feel, even in the vastness of the great outdoors.

The trail is gradual and very well defined.
Looking back at the basin from where I came.
Later, on the plateau, I walk a few kilometers along the old road, with two tracks as evidence.

I start my hike in the cool shade of the forest, enjoying the peaceful surroundings. As I go on, the trail leads me to the bald slopes and a vast plateau, where the path resembles an old road, making it easy to walk. I climb up to the North Arc Dome summit plateau, then descend two hundred meters to a saddle between North Arc Dome and Arc Dome. From the saddle, there’s another three hundred fifty meter ascent to the summit.

I spotted wild horses roaming freely in the distance.

This is also the spot where, after a lengthy walk, I first catch sight of the Arc Dome summit.

Final climb onto the summit slope.
North Arc Dome consists of a vast plateau spanning a few square kilometers, surrounded by valleys.

The summit is marked with a benchmark, offering remote views all around. After savoring a traditional apple, I start down the same path. At the first fork, I turn right, aiming for a loop. The trail is pleasant, with a few short re-ascents of about fifty meters. It then becomes a wide, gradual path with stunning valley views. Lower down, there are a few short, wet sections, but they’re manageable.

The summit is rocky and bare, marked with a benchmark.
On the return journey, I take a detour off-trail to North Arc Dome and admire the nice eastern cliffs.
A green forest lies on the east side of the ridge.

That must be Alkali Flat in the distance.
On the return, I chose a different east trail.
A few patches of snow do not pose a problem.
And a final glimpse of the North Arc Dome summit before I descend.
An easy, gradual trail down gives me the chance to admire the green valley instead of focusing on my steps.

Arc Dome was my last Nevada ultra, leaving no more Nevada ultras for me to climb. Whether that’s good or bad, I can’t say, but it means adjusting my goals. To keep climbing peaks in Nevada (and I definitely want to), I’ll need to lower my prominence criteria to around 1000 meters. With that decision made, I get back in the car and start driving toward my next adventure: Mount San Antonio, near Los Angeles.

And one more Nevada desert-like sunset.

RouteI park at the campground at Stewart Creek Trailhead and meet Iris and Tom, fellow peakbaggers who summited Arc Dome. I start my hike in the leafy forest, gradually ascending to the first plateau. Crossing it on old road tracks, I then face a steeper climb to the second North Arc Dome peak plateau. After crossing this, I descend a couple of hundred meters before making the final ascent to the summit, which is marked with a benchmark and offers nice distant views. On the way back, I choose the east trail to make a loop. There are a few patches of avoidable snow and two short fifty-meter re-ascents. The descent along the green valley is very pleasant. Lower down, it gets a bit wet, but it's not a big issue.
