2021 6-6, TRNP South Achenbach Backpack Trip

The South Achenbach Trail is one of the most remote trails in North Dakota’s Theodore Roosevelt National Park. Jean and I had tried several times previously to do this trip, but each time were defeated by high water in the Little Missouri River. The trail is isolated on the south side of the river, cut off from all the other roads and trails in the North Unit of the park, and requiring a ford of the river just to start.

In planning our Badlands trip for 2021 we noticed right away that it was a very dry year. By spring there had already been three major fires in the area, and we could tell by the stream gauges (~1.5’) that the Little Missouri River was already very low. When we got to the park, the river looked lower than we’d ever seen, and the rangers confirmed that we would be able to safely cross.

We spent our first day helping out the Maah Daah Hey Trail Association with their annual National Trails Day work event by surfacing (hauling and packing in gravel) part of the MDH trail just south of Medora. The next day we drove to the North Unit, arriving as the Visitor Center opened to get our free backcountry permit. We got the permit and an update on conditions (Hot and Breezy) and water (No drinkable water available) and left our car at the trailhead in the Juniper Picnic Area.

It was a short walk to the riverbank where we faced the biggest challenge of the trip. But luckily for us the river was only calf deep and the bottom was sandy and sturdy. The edges were muddy though, and our shoes and clothes were a mess after stomping our gear through the river bottom.

Our ranger had told us to bring a topo map, but we found right away that the trail on the ground didn’t follow the route on the topo maps. We immediately turned south to follow the river downstream through a pleasant open grove of cottonwoods, then across the bottom land to the base of the Achenbach Hills. Marker posts were few and far between, and a maze of bison trails (as is usual in TRNP) made the NPS trail indistinguishable from game trails. But there were just enough posts to get us to the mouth of a small draw then up to a patch of prairie on top of hill 2538’. Once out of the river bottom we enjoyed the best views of the hike across the badlands, at least until we reached the prairie when the wind blasted us. With pretty much nothing between us and the Rocky Mountains, the wind on the prairie tops here howls enough to buffet about even heavily loaded hikers. The trail posts remained far apart, the whole route seemed like a giant game of hide and seek.
The Achenbach Hills.
We lost the wind dropping into Park Corner Gully and began a section where we would traverse along the north face of the Achenbach Hills. Despite the lack of other obvious trail work elsewhere, in one grove we spotted a recently cleared blow down. There were a few shaded sections of thick juniper trees, and in one of those we got the surprise of the trip, another backpacker. This poor guy had started his hike in the same heat that we battled yesterday on our work trip (but without the frequent delivery of water and ice), and had spent the night just across the river from Juniper CG after stocking up with water at the picnic area. We would be the only hikers he would see on the trip.

Next up was the junction with a side trail to Achenbach Spring. I had only hiked this trail previously in 1988, and had no memory of whether or not I had visited the spring on that trip. In any case, the ranger was correct, there was no water to be had. An elaborate set of fencing, water pipe, and water tanks had been thoroughly disrupted by several generations of bison, leaving just a few muddy footprints. I got back to Jean at the junction just in time to save the other hiker the effort of hiking down to the spring.

Beyond the spring we enjoyed some more sheltered walking and long distance views. The descent to the river was broken up by the series of badlands tiers that we’d learned to expect. River views were sparse though, and it appeared there was a substantial growth along the banks that might limit camping opportunities. Our hope was to camp as soon as we hit the river bottom, rather than at the ford, to shave off the distance we would need to carry our packs heavily laden with water.

As soon as we hit the river bottom we ended up in a muddy stretch along a small creek. We reached the ford with no camping spot in sight. We both took long futile bushwhacks through the brush, then I spent a long stretch hiking back to the small patches of grassland above us without finding any good tent sites, though I did spot a long bone and other fossils weathering out of a layer of gumbo. Finally, we gave up searching, and I walked down to the river crossing looking for a spot where I could gather water. Looking further downriver I spotted a few sparse cottonwoods on a little bench above the river. Eureka! Here was a tent spot, cook spot, and nice bluff to watch the river from. We hauled our gear out to the site and made ourselves at home.

Jean then found an old plastic planter that must have washed down the river, just the right size for sitting, or use as a table. Having this simple amenity made the campsite seem more luxurious, especially nice for sitting and watching the river. We got some water from the river, let it settle in a pot and then filtered some for the next day’s hike. We boiled the next potful for dinner, grateful that the low flow in the river gave us some clay in the water, but not the silt that a more vigorously flowing river would have carried. Despite our vigilance watching the river, and a huge number of animal tracks, we only saw one deer come down in the evening to drink.
Our tent site.
With no rain in the forecast, we didn’t use the tent’s rainfly, giving us a fantastic view of the night sky. Our nearest neighbors were likely 5 or 6 miles away in Juniper Campground, or snug somewhere in some remote Badlands ranch. Coyotes howled all through the night.

The next morning, we planned an early getaway as the 90F+ heat was predicted to return by noon (after a forecast high of 77 for our inbound day). We pumped another pot of river water that had settled overnight, and then boiled another for our breakfasts. We would have about three quarts each for the long walk out.
Yummy cooking water.
After packing up, we made one false start to retrieve a precious water bottle that fell out of a pack descending the bluff by our camp. Otherwise, the return hike was the mirror image of our outbound, except for the cooler temperatures of the early morning and a slight change in course to correct a navigation error from the day before. The winds on the prairie were milder. I took a few more GPS waypoints on the return, hoping to strengthen my write-up for the trail in my guidebook. I also confirmed that no traces remained of the old tracks shown on the topo maps, and that the trail was not as mapped at the east end near the Little Missouri River. Even accounting for the need to re-sign the ford every year based on changing conditions in the river bottom, the significant issue remained that the trail is not signed along the mapped route between the river bottom and Point 2538’.

We found a less muddy, knee deep, place to cross the Little Missouri and were back at our car in the Picnic Area shortly after noon, with the heat still tolerable, and at least a splash of water left in our bottles. Jean’s boots had delaminated at some point in the hike, perhaps from the heat in our driving trip. Hiram had a large heel blister, probably a result of not being used to wearing his heavy hiking boots.

This would be our only visit to the North Unit on this trip, so we decided to drive the Scenic Drive, stopping at Riverbend and Oxbow overlooks to take pictures. We first drove the campground with the idea of spending the night, but even with several sites open, the afternoon promised to be too hot for comfortable camping. Driving out we were surprised to see two Texas Longhorn Cattle, part of the park’s demonstration herd. We’d missed the cattle on our last few visits and had begun to wonder if they were still kept in the park. Despite the midday sun we got good pictures from both overlooks. At Oxbow we could see far enough downstream to see the section of river just above our campsite.

Real Texas longhorns.
For the backpack trip I had purchased the latest copy of the TRNP Trails Illustrated map  and had noticed two “changes” to check out on the drive out. The first was a 0.4 mile connector from the Scenic Drive to the FS Wolf Trail. Though we saw no trailhead or parking for the connector, it looked like there was an old two track road in place that might mark the route. The second change was a trail from the prairie edge down to the river bottom just to the east of Oxbow Overlook. We saw no evidence of this trail, which was likely a mis map of an old pre-park route. We confirmed with a ranger at the North Unit VC that both changes were errors.
