VA Shenandoah National Park: Nature Diary - October 2020

 From my week roaming the trails of the Northern District of Shenandoah National Park...



I took my phone and a small sketchbook with a tiny watercolor set and pencils/pens. The longer I hike, the smaller (and lighter) my materials become. I carry compact 8 x 21 Pentax binoculars with a close focus setting for observing insects and flowers within half a meter. The birding was great in the thick of fall migration! 


Eastern Towhees in a migration flock at Indian Run Spring.


I witnessed a large flock of migrating Eastern Towhees at Indian Run Spring and found myself surrounded by Wild Turkeys at Snead Farm. Some of my sketched observations were done sitting very close and still near my subject, like the Timber Rattlesnake. I sat with the Towhees at the spring and sketched all their antics in and around the water. The bears, however, were done quickly from memory as there was no time to retrieve my materials from my pack without alerting Amos to their presence and besides, they came and went quickly. 




The fungi were really prevalent this week, despite there not being a lot of rain lately. All the different kinds of fungi represent biodiversity of all those species they depend upon.  The more fungi, the more stable an environment tends to be. It was interesting to think about the past century of Shenandoah National Park as a hundred years of rewilding from when the mountains were heavily logged, cultivated, cleared, and grazed. The presence of many types of fungi represent an environment rich in ecological process and diversity. 

Dyer's Polypore - a great dye for yarn - pick now!


A speaker at the The North American Mycological Association stated in a recent conference that we have only named less that 5% of all fungi on earth! Whoa. I'm not a big consumer of wild mushrooms - I let my cousin Molly handle that - she's an expert. But I did observe how many mushrooms were bitten into, tasted, browsed, chomped on, and chewed through. I noted where entire patches of mushrooms were gobbled up and the ground all around disturbed. I didn't know if SNP is plagued by wild boar, but the amount of ground disturbance to get at those tasty fungi reminded me of hiking the Piedmont in South Carolina where boar are a big problem in some places. This time of year is so important for animals that need to store up body fat for winter so maybe these were bear patches or places where deer have dug.


Clustered Bonnets


I met up with a local hiker who was carrying a basket. She was collecting bracket fungi of different types and showed me a bunch of bright orange-y brown polypore she had pulled off a stump. All of the fungi in her basket were for dying wool. This is time to collect them while the colors are bright. She pointed out a clump of Dyer's Polypore for me to photograph that were too small to collect. She was only collecting a few pounds specimens four or more inches across and just a few pounds.  




Brittlestems


Oyster Mushroom


Spotted Wintergreen, Lands Run Road


The presence of Pines together with Oaks meant the soil was really acidic and this was when I found acres of Spotted Wintergreen, Chimaphila maculata. The flowers are long gone but the creepy eyeballs are everywhere. This was an important plant for indigenous people and still has widespread medicinal use across the Appalachians. The bracket fungi lady also had some of this in her basket.  I didn't take her picture because I wasn't sure of she was permitted to collect in SNP, but she was being very careful about only collecting small amounts of things and only had a few rhizomes of wintergreen in her basket.  Wild collecting is still an important aspect of Appalachia culture and I know it is allowed in many national and state parks with permission. 



Sunroot (Appalachian Jerusalem Artichoke), Dickey Ridge Picnic Area

Another item she had in her basket was very recognizable and she collected it right off the roadside at the Dickey Ridge picnic area. She called it Sunroot - the Appalachian name for Jerusalem Artichoke - which isn't from Jerusalem or even an artichoke. She'd collected only the tubers from the spent plants, however, and not the still-flowering plants. She was going to plant these in her garden, she said. I did that once and now I have Sunroot all over the place, I replied. The tubers of this sunflower are edible but I've never acquired a taste for them. I found them later when I went down to the Visitor's Center to get wifi for a meetint. I also found where she'd dug a few tubers from a frost nipped patch.

American Salmonfly, Lands Run

If you see someone lifting rocks in a stream with a curious coonhound looking on, it's probably me. We found this handsome American Salmonfly, Pteronarcys dorsata, under a stone and I was pretty stoked about it because this is a prime insect indicator of pristine waters. We actually found several  more nearby. A couple of hikers from Columbus, Ohio, soon joined me and they were amazed by all the aquatic life to be found. We were very careful to lift and replace the rocks gently, but the Salmonfly is known for playing possum so I did poke this one and it dramatically flipped off the rock "dead" into the water and floated to the bottom belly-up before scurrying back under its home rock. 

Caddisfly, larvae encased, Lands Run

More rock lifting revealed entire Caddisfly towns, but I don't know which species these were. Very, very tiny. Amos and I had bushwacked to the headwaters of Lands Run about a quarter mile up the mountain before it tumbles through and over greenstone cliffs into the ravine below.  There had been little rain this week so the headwaters was more like a seepage with some small puddles and that's where we found these tiny constructions. Lands Run would be a great little creek to follow from its headwaters near Skyline Drive to its joining with Gooney Run in the valley and then with the South Fork of the Shenandoah. Of course, flipping rocks the whole way...

Timber Rattlesnake, Overall Run Trail

This was one of the best sightings of a Timber Rattler,  Crotalus horridus, that I had all week (2 more but crossing the road at night). It was just shy of  three feet and while the air was still cool in the early morning it was sitting on the warm, rugged trail to soak up some heat. I asked Amos to lie down and be quiet (treat involved) while I sat down on the trail to study it. We visited for a while. This is when my close focus Pentax binocs are great. I was able to study its scales and eyes and flicking tongue from eight feet away while it was gentle and calm, even turning towards me to "taste" my space. Only three full buttons on its tail so a younger one. 



My sit-down-and-visit-awhile approach to snake observation has worked well since I was a kid. I've "visited" with Hognose, Eastern Kings, Pygmy Rattlers, Copperheads, Black Rat Snakes, Pine Snakes, and Mud Snakes over the years and have had the opportunity to really do some nice life sketches. (The only snake that doesn't permit portrait-making is the Northern Watersnake which thinks the fast moving pencil or pen is worth a strike.)  All snakes know when harm or calm is present and how they react to us is entirely dependent upon our reaction to them. A guy from New York came down the trail and saw me sitting there with the snake and soon he was sitting too. "This is absolutely amazing!" he said. "What a beautiful, beautiful creature!" (Dave M. - he was your stunt double.)  After a half hour the Rattler slowly moved to the side of the trail and curled up under a log invisible to any more hikers coming this way. We all said our goodbyes and continued on with our hike to the falls. 


Hickory Tussock Moth (cat), Overall Run 

I know that these guys will give an itchy prickly rash if handled, so I just took its picture and let it go on its way. It'll become the Hickory Tiger Moth, Lophocampa caryae. Interestingly,  this was the only moth I saw flying in the cool mountain air for the entire week and I came across the caterpillars on every day's hike. 

Northern Two-Lined Salamander, Overall Run headwaters

Amos and I had a lot of fun lifting rocks in the headwaters section of Overall Run to look for "sally" before our steep climb down into the ravine. This Northern Two-Lined Salamander, Eurycea bislineata, squirmed out of a rock-covered puddle and ventured on across some gravel to a pile of leaves where it not only blended in instantly but it chose the yellow Tulip Poplar and Maple leaves to hide under rather than the brown and red leaves nearby. These guys love Appalachian springs and headwaters - anywhere there are tiny pools and rocks. The males have tiny teeth to nip the females with to encourage mating. They do migrate in breeding season, but not very far, so are basically homebodies. We saw a Red-Backed Sally too, but I didn't capture the picture before Amos stuck his nose under my phone to sniff at him. So I have a picture of Amos' nose instead. 

Greenstone quarry, Lands Run Road

I love geology so this week was a great chance to get to experience hiking through ancient lava fields that are known collectively as the Catoctin Lava Formation, a widespread area that runs from north of Gettysburg, PA, to Lexington, VA. This formation is the result of the tearing apart of the old continent Rodinian and the opening of the Iapetus Ocean (the ocean that came before the Atlantic and the break up of Pangea). The tearing of the crustal plates ripped open the valley floors and flooded the area with  molten material. The rift valleys were buried under 1,500 feet of lava and now we hike through its weathered remains in SNP. 


Greenstone, Lands Run Road quarry
\
Metamorphosed basalts became greenstone which was used by settlers and farmers extensively for building stone fences, roads, bridges, and foundations. Some historic homes still standing outside the park are built entirely of Greenstone and have withstood centuries of time. It's a mountainous landscape entirely born of fire but with uplift and weathering is at the mercy of climate and water. 

Overall Run Falls runs through a thick bed of Greenstone.


Lands Run Falls, incised lava bed creek.


Columnar jointing, Compton Peak - Catoctin lava formation.

The most amazing encounters I had with the local geology was hiking to and observing cool formations of columnar jointing. Basalt has this crazy way of crystalizing as it cools which results in six-sided columns. This is the same rock type that forms the Devil's Tower in Wyoming and the Sheepeater Cliff in Yellowstone. The formations in SNP however are millions of years older and have weathered a lot so that what you see are large boulder fields of crazy blocks and columns scattered all around. 

Fort Windham Rocks - Catoctin lava formation

The formation at Compton's Peak was a difficult climb down and back up to see, but well worth the effort. The formation at Fort Windham Rocks was an easy find along a trail and afforded plenty of opportunity to scramble around and over the outcrop. Viewing the top of Hogback from an overlook I could see the massively weathered columns broken by freeze-thaw and exposure but that displayed the characteristic six-sided symmetry.

American Oil Beetle, Little Hogback

This little American Oil Beetle, Meloe americanus, is best not handled because she can expel a powerful chemical oil that burns like heck. I know this to be true. So when Amos wanted to nudge it with his nose, I gave him a firm "No!"  These little beetles are clever too. When very small, they'll hitch rides on honey bees by staking out in flowerheads and latching on. When the bee returns to the hive, the baby beetle detaches and pigs out on pollen cakes packed into larval bee cells. No harm to bees except for stealing food. I know this to be true, too. 

Carolina Leaf Roller Cricket, Mathews Arm Fire Road

Ever see tender leaves of Spicebush or Witch-Hazel rolled up tight into a tube? Probably the work of the Carolina Leaf Roller Cricket, Camptonotus carolinensis. I had no idea what rolled leaves like that until this trip when I walked through a Witch-Hazel thicket and pulled a few rolled leaves apart, all of them empty except for one that had this incredible pair of hairs sticking out. Turned out to be antennae connected to the Leaf Roller Cricket inside! I left that one intact and found this one on a trail post preening her long, elegant antennae just beyond another Witch-Hazel thicket which I'm guessing is there leaf-rolling neighborhood of choice. 

American Cancer-Root, Compton Peak

I found American Cancer-Root, Conopholis americana,  just about everywhere because there were Oaks just about everywhere, but this parasitic plant was a ways past its creamy-colored phase. In fact, all of the Cancer-Root I found was brown and drying out. Still cool to look at, though. It has nothing to do with cancer treatment so I don't know why the name. It is purely a parasitic plant, thus no chlorophyll of its own and derives everything it needs from attaching itself to the roots of Oak trees. 


Eastern Crayfish, Lands Run

The coolest (and most heart-pounding) sighting I had was a rather close up encounter with a Momma Black Bear and her two cubs. I was taking a break with Amos on a very steep uphill trail and Amos, being tired from the long difficult hike, actually had his eyes closed laying down.  As we rested, the three bears crossed the trail only about 30 yards ahead of us and Momma noticed me standing there. I was praying Amos stayed asleep! His coonhound instinct to yowl and bay would have surely caused a scene. Luckily, he did stay snoozing and the bear moved her cubs quickly and quietly down the hillside.

VA Shenandoah National Park: Northern District Hiking

The Northern District of Shenandoah National Park in Virginia made for a week of exploration, hiking, and even playing a little catch-up with work and research basecamped at Mathews Arm Campground. Each day I set out to do a minimum of five miles hiking while setting aside time to work on projects I've had no time to tackle in this new universe of work-from-home/ at-work-all-the-time daily routine. I finished a journal article, did some artwork, attended Zoom meetings for work, and did 30 + miles of hiking. I considered it a major victory week for not a having heard one notification bell alerting me of new emails. This was also a work test for a future nomad adventure.


North Entrance at Front Royal, VA

Day of arrival, late afternoon hike on the Traces Trail

After arriving at Mathews Arm Campground off the Skyline Drive, the major road through the park, Amos and I set out to hike the Traces Trail accessed from the campground entrance. Setting up camp could wait as daylight was quickly fading and we needed to get a good walk in after three hours driving. We made a fast circuit hike through beautiful transitional forestland where one can still see the outlines of old pastures and stone fences. It is important to remember when hiking these mountain landscapes that nothing is totally "natural" and very few places within this large Eastern park have not been modified by human activity in the last century.  More on that in a future post. Once back at camp, it was an easy task to set up my simple site - tarp, work table, stove, water. My little SUV provided sleeping room for both Amos and I and was warm and cozy.


Starting Day Two in morning fog.

Day Two dawned with mountain fog blanketing the highest peaks and we set off to hike a six-mile loop around Hogback and Little Hogback Mountains in mysterious light. Using a combination of trails, including the Appalachian Trail, we traversed old roads, rocky footpaths, and pasture traces (now trails), to circle the mountain along its flanks and summiting two peaks. Gildart names this the Sugarloaf-Keiser Run Road -Hogback Lariat with an added mile to the forested summit of Hogback. Little Hogback afforded a great westerly view but Hogback Mountain was a bit of a let down as its highest point was socked in with a rather ugly radio repeater station and tower. Never mind, the hike was wonderful and we saw so much along the way. More on that later, too.


Day Two:  Hogback Mountain Loop

The Appalachian Trail is always close by - or underfoot.

Day Three we hiked a combination of trails that lead off the Compton Gap parking area for total of five miles. We started with a morning loop past Fort Windham Rocks, across the Dickey Ridge Trail, connecting to the AT and a visit to Indian Spring. Then off to find wifi for a Zoom meeting (work). We returned for the second hike from Compton Gap to the fantastic outcrop of columnar jointing and summit at Compton Peak and an out-and-back lollipop towards Jenkins Gap on the AT.  This second section is where we met a family with a leash-aggressive dog that the owner could barely control. It yowled at Amos with its teeth bared and its family all screaming for it to stop. Amos was trying to protect me and accidently pushed me over into a scree pile. A little cut-up and angry, I waved off the family when they approached (with the angry dog!) to see if I was okay. "Go away!" I said. Amos was very helpful in the steep climb and rock scramble down to the rock formation on a side trail. He stayed on alert the whole afternoon.

A bit of a rock scramble to get here but worth it! 


Day Three we hiked a nine-mile loop that took in Overall Falls and a remote mountain ridge trail. We'd already seen a bear at a pull-off on Skyline Drive, but this hike encompassed such great bear habitat that I knew we'd more - and we did. Two cubs and a Momma bear! We also saw a Timber Rattlesnake and stopped to visit with it for a few minutes. This was a hard hike and we were both dragging at the end, but luckily it started and ended practically at my campsite with no drive needed today. The Overall Falls Trail was weak on water but huge on steep, treacherous climbs down into the ravine where hikers can find a nice cascade and a sheer drop falls within a mile. Overall Run Road made for some very rocky and slow hiking and the return up Beech Mountain Trail was up, up, up. This connects with the Mathews Arm Trail, an old farm community and fire road road to the saddle between the peaks at Mathews Arm Campground. This was a modified version (longer) of the Tuscarora-Overall Run Trail Loop in Gildart's Falcon Guide (see below).

On Day Four I had a morning Zoom meeting to attend so it was back up the road to the Visitor's Center for wifi service, then an afternoon exploring another old woods road and Lands Run Falls. Amos seemed a little sore from the previous day's nine mile hike so we only did five miles on an out-and-back on the old road. He had plenty to explore though, and we spent a good amount of time peering under rocks in the creek looking for aquatic life. More on that later, too. We also hiked a section of AT - about a mile - around an old CCC camp and Amos had his picture taken by a nice park maintenance worker who showed us photographs of the camp mascot in 1935, a Black and Tan Coonhound named Blackbird Joe.  We had a great conversation with him and wandered some more around the old camp.

Some wandering after our hike found this great site.

On our last day we did a few slow miles on the Dickey Ridge Trail and Snead Farm Loop. Amos was a little tired and so we took it easy. I'd massaged his paws the night before and checked for cracks or cuts and found a little blister between his toes. He can go a long time hiking, but when he's hurting or sore, he's he first one to say "time for a wander, not a hike." Still we did just under five miles, slowly (it took hours) and Amos was very happy with all the smells and cold spring water stops. 

Dickey Ridge Trail

Snead Farm Road

Our last lunch on the trail was at the Snead Farm barn.

Total hiking thirty miles for the week with a few extra miles of just wandering and exploring. I'll post another time on the plants and animals we saw. Amos did great but I was paying very close attention to his paws as many of the trails we hiked were very rocky and he wasn't wearing boots like I was! This was prefect weather for strenuous hikes, cool and breezy with the coming of deep autumn. It's good to remember that any trail leading off from parking areas along the Skyline Drive always goes down, so saving snacks, water, and energy for the long, steep returns is important. We stopped and gave water to one exhausted hiker and his small collie who were just slogging it uphill. The AT is really the only trail that travels the ridge line with less ups and downs than all the side trails and old roads. Next post will cover geology, plants, and animals. 



Notes:

Bert and Jane Gildart offer a nice set of hikes for all three districts of the park in their Falcon Guide Hiking Shenandoah National Park, Fifth Edition (2016). I wouldn't rely entirely on this guide book, however, since there are so many more trails to explore or combine with what they have here. I used my All Trails app as well as a small booklet on circuit trails I picked up at the Dickey Ridge Visitors Center. 

I stayed at the Mathews Arm Campground just off Skyline Drive in the Northern District. It was the perfect basecamp from which I could go hiking each day whether by car to a distant trailhead or right out of my tent site. There are no showers and the campground does close in November for the winter. https://www.recreation.gov/camping/campgrounds/232432
