The photos in this first section
are from the Spring 2000 trips.

Here's
what the the trailhead looked like before we began working. It was
still fairly open since it was only January; but once the bushes and trees
began to come out in the spring, you could hardly see in here. This
looks as much like a trail as it does because it is a short cut to the
other parking lot from this one.
|
|
Compare
the first picture and this one to the picture 3 below... it really is the
same place!
|
|
The
newly installed trailhead from off of the parking lot. This
staircase began the relocation which replaced a badly eroded 'herd path'
which went directly up the hill. Much more inviting and much less
likely to wash away with use and weather.
|
|
Many
hands and some old fire hose make this 400 pound railroad tie almost
portable! (We used over 50 of them!!) They are recovered ties,
mostly hardwood, all treated for the ages.
|
|
This
is where most of those railroad ties ended up. While this isn't very
'rustic' as trails go, the level of usage is so high along here that the
sandy clay that makes up the hillside would have just been eroded away in
no time. With cribbed steps like this, the hundreds of people a day
that use this trail in the summer will have a safe, easy way to go that
will last for many, many years.
|
|
Great
work, people! You are right to be proud of the job.
|
|
A
view back down those beautiful stairs. And this is only the first
300 yards of the relocation and restoration! The overall job is just
about 2 miles long. This part is where you first come off the
Dunfield Creek parking lot, and is the most concentrated traffic area on
the trail.
|
|
It's
not all staircases. These terraces and side hill work make the
ascent to the top of the plateau pleasant, durable, and still give the
hiker a sense of being on a trail. This photo shows what happens at
the top of the staircase above. The hiker is now walking up a series
of terraces which angle up the side of the hill, curving with the general
topology to reach the top. The result is a trail that is easy to
walk on and yet 'gets the job done'; while at the same time preserves the
normal flow of water off the hill as much as possible.
|
|
And
this shows how it got to look that way. Plenty of skilled, hard work
- done with care and an eye for keeping the footing comfortable while
keeping just enough out-slope to shed the water off the trail.
Keeping the water moving along it's normal path down the side of the hill
is far better than letting it collect and gutter down the trail, causing
ruts and eroding out the steps and trail. [ Someone once said the
three most important things in trail work is "Drainage, Drainage,
Drainage" ]
|
|
A
practiced eye for keeping the drainage working, a lot of digging and
moving rocks (and more of those railroad ties).
|
|
Members
of the all-volunteer crew working away on 'side hilling' the top of the
approach to the plateau. By cutting down on the inner (up hill)
edge, they are carving a sort of shelf for the trail to be on. With
just enough out slope, the rain will continue to run across and off the
side of the trail, rather than down the walkway - which would create an
eroded ditch.
|
|
And
did we say rocks? This one ended up as a foundation for one of the
staircase landings. Wouldn't you know it... it's completely dug into
the dirt, so only the top shows! The saying goes, if you can move
the rock by yourself, by hand, it is way too small. Ideally, rocks
should be 'planted'; but in any event, they should stay where they are put
because they want to.
|
|
The photos in the next section are
from the Fall 2000 trips.
While the fallen leaves hide some of our earlier work (as intended), the
open canopy makes for better lighting...
|
|
After crossing the top of the
plateau above the parking lot, the trail's path used to follow a shoulder
of the hill around and on up. Over the years, this section, which
was the same sandy clay soil, had become pounded down into a ditch.
And, as happens with any ditch on a hillside, it became a runoff
path. The runoff had washed a pretty nasty gully, but hurricane
Floyd finished the job - in places the ditch was waist deep. The
answer was to re-locate the trail all together and to fill in the damaged
area and let it heal. This stone staircase is how the trail now gets
up to the ridge spine. These rocks are all placed and fitted into a
natural defile in the ledge face. With water bars above, very little
water will flow over them; what does will flow over the large rocks and be
dispersed through the gravel underneath.
|
|
Just
after the top of the stairs, the new trail re-joins the old trail.
(It comes in from the left in this photo; the washout began just off the
edge from here.) More large (300-400 pound) rocks were dug in and
placed to act as both terraces and a staircase at this point. The
leaves and branches are hiding the half ton of rip-rap (little rocks and
broken up bigger rocks) to the immediate right edge of the steps.
This spot was the 'headwater' for the washout gully and had to be made as
'hard' and water proof as possible.
|
|
And
this is part of it's support system. These steps were created to
form another terrace and water deterrent. They tie in to the
boulders which were already there. Now, instead of a sluice, there
is a broader, rock surface for the water to sheet over. You can also
see in the background the downhill face of one of the many, many waterbars
on this project.
|
|
This
waterbar is over 12 feet long and is constructed of very large rocks,
buried in a trench. Like an iceberg they are mostly
underground. The purpose of a waterbar is to direct flowing water
off the trail, presumably back to the normal pattern of flow for the
hillside, and this one a beauty!
|
|
This
is the business side of one of the waterbars - the uphill side. As
you can see, it provides a major influence for any water flowing on the
trail to make other plans. The real trick with waterbars is to not
make them so tall that people trip over them, but tall enough to do the
job. Also, making the outflow as diffused as possible will help
avoid downhill damage.
|
|
Here
you see a couple of the ladies at work on another waterbar. In this
case, she was lucky that is was only some small roots in her way.
Its pretty much inevitable that you will have to fight to dig a 1.5 - 2
foot deep slot to place the rocks, you just hope you don't discover
something really big.
|
|
The
uphill side of their work of art just before the finishing touches were
applied. Notice the broad, step-stone in the center. Getting
the 'right' rocks placed correctly is what makes for a successful
waterbar. Also, getting the right angle helps... too steep and they
wash themselves out, too shallow and the water doesn't flow.
|
|
And
the stairs just keep on coming. This time, it was a 3-step job,
around an existing boulder. Again, the steps are to 'harden' the
walking surface in an area where water and footsteps are making an erosion
pattern. The waterbar which ended up just above here took most of
the water away, now these steps will correct what already had happened,
and help to prevent any further damage.
|
|
After
the steps are completed, rip-rap and little 'junk' rocks are used to scree
in the side of the construction. This helps to define the intended
walkway, and to help drain water off the steps. The water flows
between the rocks and thus is slowed down, minimizing the erosion of the
area. In many cases, we will scree in an area such as this with
really 'ugly' rocks - specifically to keep hikers on the trail. If
there was enough of an erosion problem to warrant the steps in the first
place, having folks detour around them would only create new problems
'over there'.
|
|
And
here you have a view down a section of the newly revamped trail.
While we didn't place the fallen tree in the background, we did place the
waterbars and terraces. Hopefully, we will have done our job well
and helped to preserve the trail bed, and to help it heal - all while not
being too intrusive to the hiking experience.

The photos in this
next section
are from the 2001 & 2002 trips.
The work time over these two seasons was limited since the crew's efforts
(and those of most of the Trail Conference's NJ contingent) were focused
on the Pochuck wetlands relocation project on the Appalachian Trail.)
|
|
About
a mile up from the parking lots, the trail makes a 'jump' up onto a small
ledge. Twenty years ago, the trail used to just go straight up or
down the 20' cliff face, before continuing on up to the top. About
10 years ago, that was moved to a 30' high rock scramble about 200' to the
south. The only problem was that there were several seeps in the
hill above which turned the whole thing into an ice cube jumble in the
winter. Even in summer, it had a tendency to be wet and slippery -
just generally unpleasant to do business with.
So,
as an offshoot of hosting an ATC workshop on rockwork, the crew built an
extensive re-route around the rock scramble. It begins here with
several stone steps up to a 'crushed' rock tread way, which turns left at
the top of this photo. |
|
This
picture shows the "crush-and-fill" as it gently traverses about
20' to the next staircase. Monica headed up the team that built this
beauty. It curves and snakes it's way around an outcropping of the
ledge and winds up circling behind the tree you see in the middle of the
top of the frame. |
|
From
the top of these stairs, another 30' or so of stone retaining wall was
built and back-filled with crushed rock. In this photo, Jack is
standing back by the tree, placing one of the final steps of the
stairs. In the foreground, Bob and Denise are working on upper end
of this lower section's retaining wall. The base of an upper
retaining wall is on the left side. Bob is on the stone-step
landing which connects the two parts of the switchback. You can see
the rock terraces going off to the left side. |
|
Now,
what's all this talk about "crush-and-fill"? Glad you
asked! Since the local gravel purveyor doesn't make house calls half
way up the mountain, we have another way. Here, Denise exhibits the
technique with an 10# sledgehammer. All joking aside,
by smashing rocks into small chunks this way, you get a highly compacted and stable
base for whatever has to go on top. |
|
Sometimes,
what goes on top of the 'crush' is step rocks. The staircase we
built the year before down below at the first ledge, was almost entirely
built on 'crush'. Other times the crushed stone base is used as a
foundation for a retaining wall. Many times, though, it is just left
as is. When the top most layer of the crushed material is fairly
small (golf ball sized) it is not bad to walk on right from the
start. But what happens is that over (not too much) time, the leaves
and dirt fill in the spaces between and turn the gravel into a solid trail
surface that drains like a sieve.
In this picture, Jack is cutting
the the tread for the lower section of the switchback in the rocky ledges
of the area.
It's a great way to work out your frustrations... |
|
Bob
is now standing on the turn/landing I built between the two sections of
switchback. The profile of the upper rock retaining wall is right
behind him. At the high end, it is about 10 feet tall. At the
far end of the upper section (looks like it's just behind his head) is
where this relocation hooks around and rejoins the original trail. |
|
This
photo shows the top of the upper section retaining wall before it got
back-filled with 'crush' and then dirt. Just in the lower edge of
the frame is where the relocation turns to rejoin the original
route. That's Bob, working away on the lower section's wall.
If you look behind him, you can see just how far up you used to have to
scramble. Denise is working on a small retaining wall on the outside
upper edge of the turn.
When this was all done, the old
rock-hop scramble was closed off, and the new route blazed open. Not
bad for 4 days' work. |
|
Back
down by the highway, the 'other' trailhead needed help. The trail
just sort of piled up this hillside from the picnic area and, via some
pretty well dissolved log steps, worked it's way up the hill to join the
Mt. Tammany trail on top if the plateau that separates the two parking
lots. I am afraid there are no before pictures, but this is what we
ended up with. The timber stairs spiral up and transition into a
side hill, reinforced with more timbers spiked in on the outside edge. |
|
About
150' along, the trail turns and stair-steps up to another series of
terraces and reinforced side hill. That's Larry Wheelock (NY/NJ
Trail Conference Trails Director) and Karen (maintainer of the Mt. Tammany
trail with her husband Rich) standing at about 50' above the parking lot,
about 200' along the new work. |
|
Larry
and Karen are joined here by Monica (red had) and Karen's husband
Rich. They are standing just above the 'spiral staircase' turn. |
|
Pictures
yet to come: After we finished this, we 'discovered' that we had created a
very viable loop hike out of the DOT parking lot. The only problem
was that the other end of the hike was on the other side of the plateau in
the AT lot. Since there was a very well used 'herd path' around the
front of the plateau, we determined that the final touches would have to
be to 'connect the dots'. This was finished while Pochuck was in
full court press, so I don't have any photos yet. Please stand by. |
|
On
the final trip of 2002 (and probably our final Mt. Tammany Trail trip) we
spend the day building some rock steps to get over this large tree.
The tree has been there 'forever' and is doing a great job as a check
dam. So rather than rip it out, we decided the best approach would
be to incorporate it into a structure. The new structure would get
hikers up and over, while keeping them on the trail, rather than going
around (which makes even more drainage problems). [photo by Don
Griffin] |
|
One
of the 'interesting features' of working on this trail in particular is
just how busy it is. We were constantly having to hold up
work while people came through. Here, we paused with a step rock to
let folks through. That's Norm (back, right in gray), Roland (right,
front in blue) and me (leaning on the rock). [photo by Don
Griffin] |
|
After
that batch of hikers passed along, we lowered the rock I was leaning on
into place. Here, Norm is studying the rock to define the hole which
will need to be created to seat the next step. What you don't see is
that the rock at his feet is already in a footing hole, nearly 10"
deep. These rocks are going to stay because they want to, not
because we want them to. [photo by Don Griffin] |
|
That
same step, from the front. From this angle, it looks a lot more like
a step! [photo by Don Griffin] |
|
In
fact, the next moment, some hikers came piling through. They just
couldn't wait to use the stair... But they're not done
yet!!! [photo by Don Griffin] |
|
We
need another 'big boy' - so off Norm went in search of one. Looks
like he and Roland got a goodie. Here, they are working it out of
the spot it has been waiting in for about 15,000 years. It didn't
come without a fight -- but these guys are up to the task.
[photo by Don Griffin] |
|
Here,
they have it almost out to the main zip line. They have it wrapped
into one of my 'chain baskets' and have used the winch to pull it out of
the woods to here. [photo by Don Griffin] |
|
Once
it reached the zip line, Roland scooted it (can you 'scoot' an 600# rock?)
down to the top of the log. From there, Norm, Roland and I twisted
it around into just the right position to slide it off the log. It
had to be right the first time, because it was dropping in as a wedge
between the log and the previous step. Luckily, it landed just
right. Some minor work with the rock bar and the job was
done. [photo by Don Griffin] |
|
We
trimmed out the steps with a bunch of scree rock and crush and fill gravel
to keep folks on the defined tread, and to promote drainage without
erosion. It would appear that we have succeeded. We hadn't
even cleaned up and more hikers came through. [photo by Don
