Hidden Rocks, Jefferson National Forest

When I found this hike I was looking for an enjoyable trail along which I might capture a recording of a stream without any anthropophonous intrusions.

I wanted a trail at a decent remove from denser populations. The weather for the day looked friendlier near the Friendly City than anywhere else within a similar radius, plus, I have some lovely friends in Rockingham County whom I hadn’t seen in some time. The planning process became one of seeing how many wishes I could get from one genie. In the end I scored big – it was a great day, filled with productive recreation, social engagement, and even a little music.

In my search for the ideal hike to match these purposes I stumbled across a Virginia hiking website I’ve had good luck with in the past and found out about Hidden Rocks. From their post I knew they had field tested some conflicting information found online about this hike, so I decided to let them figuratively lead the way. I found their information checked out well, though I was a little too distracted by the imminence of inclement weather and my ancillary task of making a recording to fully evaluate their directions or explore the whole loop they describe. I was also in a bit of a rush when I read their article before heading out, and had no cell service on the trail. But I didn’t get lost! Their coordinates for the trailhead were accurate. I did not find the falls, but I found the rocks (strange, eh – they purport to be hidden…). I did not go far enough to find the second crag, but the first crag is pretty spectacular.

The trail is a bit unkempt and in places quite rocky, but it is well established. We’ve had a lot of rain this spring, so the water seeping from springs onto the trail might be a seasonal feature. It looks like in drier weather there are stepping stones at most of the Rocky Run crossings, but I decided it was safer and simpler to sacrifice the dryness of my feet and just wade through them.

In the most general terms, the beginning of the trail is a lot of gentle ups and downs, followed by a descent to Rocky Run, and a slow ascent hiking alongside it, followed by the only really steep portion at the far end on the way up to the rocks. There is a path around the rock face that takes you up on top where you can look back on the ridge you’ve traversed to get there. There is apparently a loop to be made near the end of the hike, but I didn’t get to try that out (this may be why I missed the falls). Even if you do the loop, though, it’s more like a lasso – you’ll retrace the bulk of the trail back from Rocky Run to the trailhead.

Despite feeling harried by the forecast of thunderstorms and the need to spend the better part of an hour in the recording process, I was able to spend a little bit of time looking for interesting plants. The mountain laurel (Kalmia latifolia) in full bloom made for a glowing presence for a considerable portion of the trail. In one place there was a stand of it in bright sunlight at the end of a tunnel of rhododendron.

I found three different types of ferns, one of which I readily identified, Christmas fern (Polystichum acrostichoides). Christmas fern is easy to recognize by the dark green of its fronds and the stocking shape of its leaflets or pinnae. It is also quite common throughout eastern North America. The other two I will have to look up – they are both familiar, but I have a hard time remembering which is which and what the identifying features are for each.

I found a spotted wintergreen (Chimaphila maculata) growing along the edge of the trail, just about ready to bloom. Spotted wintergreen is not uncommon in the woods in Virginia, but is an endangered species in Canada and considered “exploitably vulnerable” in New York.

There is also rhododendron, in many places arching completely over the trail, enough to make me want to go back in early July when it should be blooming. The folks at Virginiatrailguide.com have identified it as rosebay rhododendron (Rhododendron maximum), and it probably is, but I understand that Catawba rhododendron (R. catawbiense) is also found in Rockingham County, so I am inclined to take this as an opportunity to further rejuvenate my plant identification skills. If I am able to return to the trail while it’s blooming I will post pictures and settle on an ID. I also found a little bit of striped maple (Acer pennsylvanicum), an old favorite of mine.

I’m usually not very good at matching any of the Latin names that rattle around my head with plants I see, but one name that always floats up in search of a match is Dioscorea villosa. I have finally gotten the common name wild yam root to adhere to this binomial, but for once this name popped up at least for something similar if not the real deal. I will be sure to sort that out and post what I find. I also noticed in reviewing the photo that there is some sort of Solomon’s seal right next to it, which I didn’t notice at the time; true or false I can’t tell from the picture.

An early stretch of the trail features a bunch of witch hazel (Hammamelis virginiana); I found some apparently healthy eastern hemlock (Tsuga canadensis) near where I recorded Rocky Run, as well as some type of Vaccinium. The onomastics of witch hazel turns out to be rather interesting, perhaps I will explore that in a future post.

The three remaining plants to ID are the most interesting to me, as they are less common in my experience or altogether unfamiliar. One is what seems pretty clearly to be a type of iris:

Another is quite possibly partridge berry:

And what the last one is I have no idea. It seems to be a stoloniferous low growing evergreen, but even that is intuitive guesswork:

I also found some groovy straightupandicular fungus, which a cursory cruising of one dichotomous key suggests may well be candlesnuff fungus (Xylaria hypoxylon) :

I mentioned making a recording. I was looking for a sound source free from human noise (planes, cars, talking, footfalls, etc.) of which to record a good half hour segment. In the future I plan to make hour long recordings, but this was a first run and there were thunderstorms on the horizon so I halved that for the sake of completion. A little ways after crossing Rocky Run for the second time I ventured a little upstream from the crossing and found a promising stretch with various features to the sound the water makes passing over the thalweg. I put on my headphones and wandered around with my recording gear in search of a sufficiently sublime susurrus. The level of water in the stream made for a sound that glossed over a lot of the features of burbling, sloshing, and percussing I was really listening for. With more time I would have explored further, but given the weather I opted for compromise. I found a small cascade with an alcove of large rocks nearby and pointed the mics away from the source of the sound and into the alcove instead. This allowed more of the percussive and dynamic nature of the sound to emerge. Next time I record a stream I want to get less white noise and more distinct features, but this will do for a start! You can stream (how appropriate) a 30 minute recording of Rocky Run here.

I definitely want to go back to the Hidden Rocks trail for further exploration on a day when I am less pressed for time. I will post further information about the plants and fungi in question as I obtain it. Now it’s time to start choosing the next expedition – I’m thinking Rockbridge or Amherst County or somewhere along the James in the Tidewater. If you have a location in mind that offers both a nice day hike and a lovely soundscape to sample, please let me know!
