Bismarck Lake Loop and Walker Lake


Despite a predicted 60% chance of rain, we set out on 27 July 2013 to make a loop hike around Bismarck Lake. To do this we planned to start at the Bismarck Lake Trailhead, hike on that trail past the lake and join with the AZ Trail. We would then follow the AZ Trail north until we came to an old road that would take us to Little Spring. From Little Spring, we planned to bushwhack our way back across a ridge that separated it from Bismarck Lake.

We left Cottonwood a bit after 0700, but I had to stop for gas and it was about 0730 when we left Cornville after picking Lila up there. We took I-17 to Flagstaff, continued straight on Milton when the freeway ended, passed under the railroad overpass, took the sharp right turn and turned left onto US Hwy 180 (Humphreys Street). We drove 12.2 miles from the end of I-17, passing the turnoff to Snowbowl along the way, to turn right onto FR 151 just after passing mile marker 235. About 6.4 miles along FR 151, we came to the Bismarck Lake turnoff. We turned right onto that road and drove 0.6 miles to the Bismark Trailhead. We donned our gear and paused for a group photograph.

We found an informative sign, providing distances and other pertinent information, posted at the beginning of the trail.

A short distance ahead we started to see pinedrop plants (rightalong the way. This plant lives in a parasitic relationship with, and derives all its carbon from, a fungus which itself colonizes a host plant's roots.

The trail rose at a gentle slope along an old road, now blocked by a fence and several mounds of earth to prevent vehicular traffic. It passed at first through a heavily forested area and then skirted a verdant meadow with a few trees scattered about.

The meadow is shown in the following photograph (below) taken on the way back down the trail.

There were several flowers scattered alongside the trail. Predominate among these were blue to purple flowers that I at first took to all be lupines. However, I later found that they were mostly loco weed.

Above, the leaves of the lupine are arranged around the stem in clusters while the locoweed has a fern-like arrangement.

About eight-tenths of a mile from the trailhead, we arrived at a fork in the trail. By bearing left, we could go directly to Bismarck Lake, continuing straight ahead would take us to the Arizona Trail. We continued straight and were soon at another sign. Both signs are shown below.

Bismarck Lake is 0.2 miles to the left
We arrived at the Arizona Trail
We turned north on the Arizona Trail, going toward Forest Road 418, and were soon traveling through a cool forested area along the bottom slope of Humphreys Mountain just outside the Kachina Wilderness area.

Lila had recently hiked this section of trail and had noted a hand-written sign pointing out the way to Little Spring. That observation led to this hike and our plan to loop around Bismarck Lake. However, when I laid out the hike and plotted a proposed GPS track, I used the route of an old road shown on my map that left the Arizona Trail at a closer spot. When we came to the old road, we had not reached the sign Lila had seen, so we continued along the trail for a short distance farther before stopping for a snack and to decide whether to return to our plotted track. One member of the group went ahead for about another quarter of a mile and returned to say that he had not reached the sign. Also, it was now threatening to rain, so we decided to return to the plotted track.

Shortly after we started down the old road, the rain started to fall and we stopped to don ponchos.

In our ponchos we were indeed a colorful lot.
Now protected from the rain, we continued on our way along the well-defined trail. The rain was intermittent and between showers the butterflies came out to play on the locoweed (left) growing in the old roadbed.

A little over half a mile from the Arizona Trail we came to a junction with what was once FR 418B, but was now long unused as a road. We turned west on it and continued toward Little Spring. Then, about 0.5 miles ahead we turned off of old 418B and followed another road for about 100 yards to arrive at Little Spring.

From here we intended to bushwhack our way back to Bismarck Lake. However, we noted a fairly well-worn trail leading up the mountain in the general direction we wished to go and decided to give it a try. As we started up the trail, I saw a beautiful berry-laden bush (right) growing alongside the trail. Luckily, no one tried eating the berries, as I later learned it was poisonous red baneberry, sometimes called snakeberry.1

The trail we were following led sharply up the mountain for a distance before leveling off a bit. Not far from Little Spring, we found an ancient tree with many dead branches. An attached Forest Service sign (left) proclaimed it to be a Wildlife Tree, not to be cut.

The trail became a bit obscure at one point where it detoured around a fallen tree. Other than that one spot, it was clear and easy to follow. Additionally, a quick peek at my GPS showed that we were following closely along the track I had plotted to guide what we had thought would be a bushwhacking trip from Little Spring to Bismarck Lake.

Along the way we saw numerous old carvings, such as were left by Basque sheepherders, on the aspen trees. One tree had both what appeared to be a cross and a spaceship (or rocket).

Once we had topped the ridge, the trail sloped gently down and the going was easy.

We stopped at the lake for lunch and, having long since removed them, now used our ponchos to protect us from the wet grass. We had a great view across the lake to the cloud-shrouded slopes of Mount Humphreys.

From here it was just a mile back to the trailhead and we were soon approaching the end of this trail.

Approaching the Lake Bismarck Trailhead
Our track is shown in red on the included map (below). The dark green track is the road from FR 151 to the Bismarck Lake Trailhead. The light green track shows the continuation of FR 151 toward its junction with FR 418. A section of the Arizona Trail is shown in yellow.

The Bismarck Lake Loop hike was exactly 5.0 miles according to my GPS. That is the trailhead to trailhead distance and excludes the extra distance we hiked on the Arizona Trail before turning back to follow our plotted track. The elevation gain was 555 feet and the maximum elevation was 8875 feet.

Bismark Lake Loop
Having finished the Bismarck Lake Loop in good time, we decided that we would drive the short distance, only 3.1 miles, to Walker Lake and do that hike too. We would then return to US 180 by way of the north end of the FR 151 loop.

To reach the Walker Lake Trailhead, we returned to FR 151 and drove north, passing the Little Spring settlement on the way, until we reached FR 418. We turned right (east) on FR 418 and drove about 0.2 miles to the first road on the left. According to my map the road is numbered 9004S. It turns to the right after almost 0.3 miles and continues for just over another tenth of a mile, for a total of 0.4 miles from FR 418. I later checked the Coconino National Forest Motor Vehicle Use Map and found that this road is not listed. However, it appears to be well-used.

After traveling 0.4 miles from FR 418 we came to the Walker Lake Trailhead. From here the road is definitely closed to all vehicular traffic.

It is just a short hike up the gently-sloping old road to the rim of the volcanic crater in which the lake is located. I was hiking ahead of the others and, just as I rounded a curve where the road turns to cross the rim of the crater, a large doe jumped up right in front of me. She, even more startled than I, lost no time in departing the area. By the time I had traversed the few remaining yards to the rim, she was just a fleeting figure far down the old road that once led down to the lake.

If you look very carefully, you can see the deer between the two dead trees
As shown below, the lake is laid out with a mixture of woods and grassland as a backdrop.

Walker Lake
The Hochderffer Fire of 1996 swept down into the bowl on the western slope and destroyed the forest in patches.

The included map (below) shows the short Walker Lake hike in blue. The green track is the route we drove to the trailhead. The magenta track is part FR 151 leading to US 180, only about two miles away.

This hike, as shown on the map, is only 0.6 miles round trip. The elevation gain is 140 feet and the highest elevation is 8345 feet.
