2015-05-16 Mapping Trips

2015-05-16 Mapping the Helderbergs

There's been too long a hiatus in blogging here, but I've been kind of busy. Still, I've recently had the opportunity to get in a little bit of walking (on easy trails: I won't dignify it with the term, 'hiking') and mapping for OpenStreetMap.

The last few mapping outing, I've been concentrating on the little nature preserves that are strung out like beads along the rim of the Helderberg Escarpment. Many of them are fairly new, since Albany County has been pursuing conservation easements and outright property transfers in recent years, to try to preserve the view as well as the unique environment of the Heldebergs.

2015-04-18 Wolf Hill

On 25 April, I did the first of these mapping expeditions this spring, starting with the Keleher Preserve atop Wolf Hill. This is a smallish (447 acre) plot, with a few miles of moderate trail. Like all of the Helderberg preserves, people tried to farm this land once upon a time, despite the shallow and poor soil. There is ample evidence of ruins. The land was in private hands until two parcels were conveyed to the Mohawk Hudson Land Conservancy in 2010 and 2014.

I hiked in past evidence of recent logging,

I quickly came to an interesting conceit that I've now seen in several of the preserves: a bridge fitted with lengths of PVC pipe tuned like organ pipes. You play it by beating on the tops of the pipe with flipflops that are tied to the bridge. I tapped a couple of bars of a Mozart melody and continued, smiling inwardly, but still more pleased with the babble of the brook.

The trail steadily ascends the hill, past a number of stone walls that once bordered fields and pastures.

I thought that I'd follow the abandoned Wolf Hill Road to the south end of the preserve, where there are reported to be some nice views. Because of the road's being unblazed, and my unfamiliarity with the preserve, I turned off too soon, down an abandoned logging road. I lost the road a couple of times, but each time I found it again and followed it south - inadvertently straying off the preserve to the best views I had all day. Just southwest of the preserve, the whole area has been recently clearcut and has a sweeping view, where the distant horizon shows the Blackhead Range, Windham High Peak, and the ridge ascending to Huntersfield Mountain.

When I arrived at the clearcut, I knew I'd gone astray, and made my way up the ridge to the correct road - which was, of course, perfectly obvious, The road was still blocked in spots by drifts of patchy wet snow, much churned by ATV's. Snow on the trail
I soon reached the powerline cut that forms the preserve's southernmost extreme, and it did indeed offer views, both east toward the Hudson Valley and the Taconic Mountains beyond: View east
and west across a little valley to the next hill, with the flanks of one of the Catskills (Bearpen Mountain?) just barely visible through the trees at left. View west

I turned around and made my way back up the road into the preserve. Where the snow had melted, I could see just how poor the acidic soil up here is: only a few inches of erosion have exposed the bedrock. The rock here is a limestone pavement, and the Devonian stone to be found here is some of the most fossiliferous on the planet. I noted the odd brachiopod and crinoid without even stopping. Bedrock
In the spots where the limestone dips or is beginning to form sinkholes, the water stands, and the ATV traffic has churned the trail into a lake of mud.

I followed the white and red trails around to where a strategically placed bench overlooks a fine view of Albany Overlook

I then walked a series of loops to pick up the routing of the other trails. I noticed at the end of the green trail that the maintainers have placed flagging in the woods, apparently marking a route up the hill to the east. I followed their flagging for a hundred yards or so, but recalled my promise to Mary Ann that I wouldn't bushwhack solo. I turned around and hiked back to the car. A nice afternoon stroll.

2015-04-25 Huyck Preserve - Hiking the Huyck

Trail marker

A week later, feeling more energetic, I went down to the Huyck Preserve, a considerably larger tract surrounding the village of Rensselaerville. Very close to the south entrance, the trail comes to a bridge,
Bridge over Tenmile Creek
that offers a view of lovely Rensselaerville Falls.
Rensselaerville Falls

On the far bank stands a ruin of what I presume to have been a mill, probably exploiting the falls for water power. I make a note to explore that further another time, and continue with recording my GPS tracks - I've some miles to make today if I'm to map the whole preserve!

The trail has patches of ice. I'm careful about my footing. Sliding into the gorge of the Tenmile Creek at the falls would not be pleasant!

Backtracking to the ruin and heading up the hill puts me on the Falls Trail, which climbs moderately but steadily through a fine stand of hemlocks, most likely planted as a Great Depression reforestation project after the local farms failed.

Once on top of the massif, the trail bends back to the river and recrosses on a wooden bridge that looks downstream over the lip of the falls.

A stairway down from the far side goes to the edge of the falls at the top, another spectacular overlook. Beyond the falls, the "snow cone" of frozen mist is still apparent, even in late April.

The trail then goes up the east bank of Tenmile Creek along the spillways of Myosotis Dam, arriving at lovely Myosotis Lake.

It passes the picnic area, swimming beach and boathouse, the Jessie Huyck building, and the Ordway house (which now serves as part of the preserve's conference facilities.

From here I proceeded up on the Ordway Trail, around the Race Track, and onto the Partridge Path. From time to time, I passed some ruins, including some wreckage whose purpose was ... uncertain. (It's too wide to be a trailer, but seems to have been made of parts of several. I've no idea what it was for.)

There are no wild flowers yet, but the corn lilies ( Clintonia borealis ) are starting to emerge. Corn lilies, clubmosses, and moss

Farther up, the first loop of the path brushes the edge of the preserve. Someone has managed to cling to his farm, and there's a hayfield right over the wall. Pasture

With the leaves off the trees, there's also a view down into the marshes, with County Road 6 beyond. The water is high from snowmelt.

The trail recrosses the Tenmile Creek on a bridge, and follows an unnamed tributary upstream toward Wolf Hill.

When it reaches the Schoharie power line, there's a view toward the Taconics. Wolf Hill, which I explored the previous week, is visible in the nearer distance.

At the north end of the preserve, yellow survey blazes mark the boundary of the Partridge Run state forest. Survey blazes

I signed the Wood Road register, and continued around to finish the other side of the loops. On the way, I passed a gate in an ancient stone wall. Some mason took pride in his trade. A wagon would still have a smooth ride on the pavement today. Old gate

This early in the Spring, the less developed parts of the trail were still sometimes running with water and full of blowdown. I tossed aside what I could of the lighter brush. Some of the heavy stuff will just have to await a chainsawyer. Washed-out trail

I followed the Wheeler-Watson trail out, which goes by the Lincoln Pond dam and the adjoining cottage, another part of the preserve's facilities, used to house visiting scientists. While there's a trail around Lincoln Pond, and another connector across the north end of the lake, I decided to bypass them. The day was starting to get late, and I still had a few miles back to the car.

I signed the trailhead register across from the cottage (I don't pass a register without signing in!) and followed the trail on the west side of Lake Myosotis past someone's experiment. The preserve is an active biological research station.

On the way, I was surprised to see a beaver working away. The beaver was too busy to notice me, and let me photograph for a few minutes, so I came away with a couple of, you should excuse the expression, wet beaver shots.

A little farther down the lake stands the ruin of another farmstead. Ruined farmhouse

I rapidly made my way back to the car, and arrived with a good half-hour of daylight, having put in roughly a 12-mile day on easy trails.

2015-05-16 Bennett Hill, and return to the Huyck

Bennett Hill Preserve

I felt as if I had to get out again today, even though the weather looked dodgy, so mapping another one of the little preserves seemed a good idea. I could always cut things short, or if the weather held, go back and do the unfinished trails at the Huyck or start mapping another one. I chose Bennett Hill, another one of the newer (1998) preserves in the Helderbergs. Like all the Helderberg hills, this one has a lot of interesting geology. Those who are interested in the complexities can find a lengthy discussion elsewhere. Suffice it to say that springs, sinkholes, and fossils are among the karst features in abundance. In fact, the entrance to the preserve is right near a cluster of four sinkholes, only one of which appears to be active (with a stream running into it that originates at a spring farther up).

On the way in, I got a reminder that the last few weeks have been bone dry, even though we started with a good snowpack. This has been a bad fire year. Fire danger

The entrance trail overlooks a dairy, with fairly good views beyond when the trees are not fully leafed out. Its nicely benched into the side of a hill, and follows a contour line for about a quarter mile before it ascends steeply about 200 feet up a couple of switchbacks.

Near the top of the climb, I caught sight of a strange object in the woods. "What's that bathtub doing there?" I said to myself. It turns out that the preserve builders, or perhaps the former landowners, thought it would be amusing to have a piped spring feed a bathtub faucet, so they set one up that way. I didn't sample the water, knowing that it will most likely taste as if it will rust your teeth!

Right at the top of the last switchback, a hiker can rest for a moment. There's a tree with bent branches that's perfect for sitting on.
Nice sitting tree

I made a complete loop of the hilltop on the yellow trail. Over on the east side of it, there's a cairn just built on a straight and level bit of trail, with no turnoffs, good blazes, and good visibility. I have absolutely no clue why anyone would have gone to the trouble of building one right there.

On the north side, there's a nice overlook with a view toward Albany and the Green Mountains. The view left a little to be desired on such a hazy day.
Approaching the Bennett Hil

I finished the loop one-and-a-half times around the yellow trail, and descended the hill on the steeper and less well-maintained red trail. There's a lot of loose soil on steep slopes on the red trail; I suspect it may be headed for an erosion problem if the maintainers aren't careful. On the way out, I heard a strange sound. "What is that?" I said to myself. "It's not a motorcycle revving..."

The farmer had let the cows into the nearby field. I was hearing them arguing over the haystack. "MOO!". My, the sound carried.

This bit of mapping had taken me only a couple of hours, and the weather still looked as if it would hold off for a bit, so I headed back to the Huyck Preserve to map the bits I'd missed. I parked up by the Lincoln Pond dam this time, and started hiking around the pond (after some delays, such as replacing the lens that fell out of my spectacles). The pond with its dam is a pretty sight, and vegetation and driftwood made interesting reflections in the water.

My beaver friend from a few weeks ago wasn't working while I was there, but I saw that he or one of his colleagues had been about.
Beaver damage

After going around the smaller pond, I walked around Myosotis Lake to map the connecting trails that I also had missed on the last visit. I found I didn't have to turn back at the dead end at the dam spillway, because the spillway was completely dry. I jumped down into the concrete gully, walked across and scrambled the other side. I grabbed a panorama of the lake from the center of the dam. Click the image for video.
Myosotis Lake I went back to my car up the east shore, getting the crossover to the north of the lake, and got back just as it was starting to rain.

The day had wildflowers in abundance, while just two weeks earlier there had been none at all. Among the ones I spotted were Geranium maculatum, which gardeners call a 'false geranium.' The 'true geranium' to a gardener, to a botanist isn't a geranium at all, but in genus Pelargonium. Go figure. I also saw wild strawberry, violets, and apple and black cherry in bloom. It was a pretty day.
