skinny tires and thaw cycles

Folks— when temps are above 28 degrees, we are asking nicely that mountain bikes stay off the trails in the park. When we’re in these freeze/thaw cycles tires wreak havoc with our trails.

These tire ruts will let the water run down the rut, and that then washes away all our hard earned dirt. Dirt in the park is hard to come by. See this for more info! It’s all moved to the trail by volunteers using buckets and shovels.

There is no paid trail staff, there is no mini-excavator working to move dirt. Please do not ruin it for everyone else.

Fall 2018 Summary by Tom Estill

The first official day of fall found a cold wind coming down from the North, helping migrating birds continue their flights southward.

Scurrying about the forest could be found black-throated blue warblers, black-throated green warblers, yellow warblers, blue jays, crows, white-breasted nuthatches, black-capped chickadees, and a solitary vireo. At the ponds you could find a belted kingfisher, a single osprey perched near its nest, a double-crested cormorant, spotted sandpiper, and wood ducks. A pair of black water snakes was also seen sunning themselves on the shore of Rocky Pond. Very happy to see all 50 American Chestnut trees were doing very well.

Last reported sighting of an osprey at Muddy Pond was on Sept. 24th. It is with great anticipation that we look forward to the return of nesting osprey next spring to Muddy Pond. Will they once again successfully nest and produce healthy fledglings as they did this year?

A walk through the forest on Oct. 6th found numerous gray squirrels and chipmunks busy collecting and storing acorns and other seeds, black-capped chickadees, white-breasted nuthatches, a vireo, blue jay, small flock of tufted titmouse, and hermit thrush At Muddy Pond you could see wood ducks, a double-crested cormorant, and at least 1000 Canada geese resting during their migration south. A peregrine falcon was seen perched in a tree at Muddy Pond, a first for me! What a magnificent looking bird. Black water snakes were still seen on the shores of Rocky Pond. The fall foliage was a disappointment this year. Our area just didn’t have the rains, and frosty nights early in the fall so needed for a good fall foliage. Warm temperatures seemed to hold on for the longest time this fall.

The first significant frost didn’t occur until Oct. 14th. On that day I saw hermit thrush, blue jays, black-capped chickadees, white-breasted nuthatch and hairy woodpeckers. I also came across 2 barred owls at Rocky Pond. And at Muddy Pond, you could still see wood ducks and over a thousand Canada geese.

On Nov. 11th, one would find the forest floor covered in leaves, and the forest very quiet. I observed but a few gray squirrels, black-capped chickadees, and white-breasted nuthatches. I started my walk at 4PM, and by the time I returned to the parking lot a little after 5PM, it was already getting quite dark.

On Nov. 17th, the park floor was covered with a few inches of snow, and where there was no snow, you would find a thick layer of oak(mostly red oak) leaves. Only a few birds were observed including a red-tailed hawk, black-capped chickadee, crows, tufted titmouse, and white-breasted nuthatch. Once again, the forest was very quiet. Very typical for this time of year. Beaver activity at Rocky Pond has been increasing the last few years. Trees felled by beaver, can now be found at least 100 meters from the water’s edge. Muddy Pond was completely frozen over, and most of Rocky Pond, with the exception of a small area of open water around the Eastern side beaver den, and the outlet into Muddy Pond. I was surprised to see a Red Squirrel near the rocky ledges under the powerlines on Carriage trail. They are not anywhere near as common as the gray squirrel in the park. Also, on this day I observed an amazing number of snow flies(midges) flying throughout the park. Never had I seen so many, so late in the season.

The first week of Dec., once again found the forest very quiet with only a few birds observed including, black-capped chickadees, white-breasted nuthatch, a flock of tufted titmouse and crows flying overhead. There was about an inch of snow on the ground, and lots of deer tracks everywhere in the forest. Rocky Pond was solidly frozen over with only a small patch of open water near the east side den and a narrow path in the outlet.

By Dec. 8th, most of the snow was gone, with only small patches left here and there. It was a beautiful sunny day, but cold. On my walk through the forest I saw only 2 gray squirrels and one hairy woodpecker. A few days later, I sprayed the American chestnut trees with deer repellent to protect them from deer browsing in the months ahead, and was not surprised to see that Rocky Pond was covered by a thin layer of water formed by the recent warm days. Both Hairy and Red-bellied woodpeckers were seen along with a barred owl near Trail Marker #24. Very quiet in the forest.

If you would like me to include any interesting or unusual wildlife sightings you have made at Pine Hill Park, please email such sightings to me, at: ​testill@cksrutland.org​ I’ll be sure to include them in my seasonal summaries along with your name.

That’s all for this issue. Please stay on the trails, and enjoy your special time at Pine Hill Park.

Pine Hill Trails and Geology

Pine Hill Park has a unique rocky landscape. You might not notice because our volunteers have done a good job at smoothing out the trails. And maybe the leaf litter obscures what is underneath. Or maybe you are one of our long-time users that have noticed some of your favorite trails becoming rockier with time. Also, as you travel on to the adjacent Redfield Trails and Carriage Trails, you may have noticed that rocky character of Pine Hill Park quickly disappears. All of this is largely because of the underlying bedrock.

The Cheshire Quartzite

Pine Hill Park rests upon bedrock that is called the Cheshire Quartzite, which is named for Cheshire, Massachusetts where it was originally discovered and mapped by geologists. It extends north and south near the boundary between the Green Mountains/Berkshires and Taconics. The Cheshire also has laterally equivalent layers of quartzite that extend into Canada and southern Appalachia, however these layers can have slightly different characteristics due to their history.

The Cheshire Formation got its start in life as a near-pure quartz sand that has since been buried, heated, and then squeezed by three subsequent collisions with other continents. All that heating and squeezing helped to make the beautifully smooth texture that compels you to lower your center of gravity (or land on your backside) on a wet day. It also causes the natural partings and breaks (faults and fractures) that can be seen in the quarry at the end of Crusher Road.

This bedrock formation is an approximately 1,200 foot thick layer of quartzite, which is entirely composed of smooth-grained quartz. The sand was deposited just off the coast of an ancient ocean. We know this because marine animal fossils have been found in other Vermont locations where the Cheshire is exposed at the surface. These fossils suggest an age of around 530,000,000 years or what is known as the early (lower) Cambrian Period. The fossils of this age are notable because they mark the beginning of life as we know it.

Poor Soil Production

Quartzite is one of the most resilient rocks at Earth’s surface. It is relatively immune to things like the acidity of groundwater and freeze-thaw cycles that obliterate other rocks. This is because of the very strong bond between the silicate molecules (SiO2) that make up its basic structure. Most rocks will break apart relatively easily (over long periods of time) along the bonds between their basic building block molecules. However, quartzite molecular bonds are so strong that breaks in the rock only occur through the basic quartz molecule, not along the edges where it bonds to others. This is still a difficult thing to do and is why quartzite breaks in glass-like shards (conchoidal fracturing) and sparks fly when struck with a hammer or another piece of quartzite.

The resiliency of quartzite means that it is not particularly good at producing soil. In fact, the very thin soil that you encounter on the Pine Park Park trail tread is glacial till material left over from when the last glaciation behaved like a gigantic bulldozer running across Vermont. The till varies from a sandy to silty texture with an orange color that is due to oxidation, much like rust. Inside this soil is jumbled (poorly sorted) Cheshire Quartzite boulders and pebbles with an assortment of rounded cobbles from other parts of Vermont. This helps explain why there seems to be no rhyme or reason to where and how soil deposits occur on Pine Hill. It is also interesting to note that virtually no additional soil accumulation took place on top of the Cheshire Quartzite in the past 10,000 years.

The above photo is from near the main entrance and shows a cut into glacial moraine material, which is much thicker than the till that sporadically covers most of the park. The sediment pile creates a sort of bluff overlooking the park and contains a variety of unsorted rocks of various sizes.

Similar Trail Systems

The way that quartzite breaks apart also means that it is not very good at providing the friction that keeps you upright. For comparison’s sake, the nearest trail system (and perhaps only) that is built upon similar quartzite is found on South Mountain in Michaux State Forest, Pennsylvania and extending into the South and Catoctin Mountains of Maryland. Similar poorly developed soil profiles are present, but the quartzite has course crystals that provide a little more friction and no glacial sediments are present.

Although it is coarse to the touch, the wet quartzite of South Mountain makes many of their trails impassable for bikes when the rocks are wet. This is because those trails are not built like ours in Pine Hill where mineral soil is brought onto the trail tread and large rocks are moved aside. It also means that the trails of South Mountain are expert-only because the trail tread is almost entirely rocks and boulders.

In Pine Hill the smooth crystal structure of the Cheshire Quartzite places even more limitations on friction between mountain bike tires and hiking boots. Every local mountain biker I know has taken a tumble on Lonely Rock. And I have seen several volunteers unsuccessfully test my warning about walking across wet rocks. Many times it only needs to be a humid day for you to break your arm.

A Rocky Lesson in Trail Building

The trails of Pine Hill Park have been built for the entire community with the goal of increasing access. This means that many rocks and boulders have been moved, trails are routed to avoid locations with no till, and that rigorous and unique trail building practices had to be adopted. In many places of the world more rocks on the trail is a good thing. In Pine Hill Park more rocks means building the world’s largest Slip and Slide or Wet Banana.

Without realizing it, the trail builders of Pine Hill were receiving a lesson in geology. With a little observing it is possible to see how this learning progressed from older rock-bordered trails that channelize water into ever-deepening ditches to newer out-sloped trails with rolling dips that disperse the water from large rain events. You can also take note that many of the trails are routed in such a way that seems to avoid rocks, which is the opposite of what builders in other trails systems tend to do.

The above photo is between intersections 30 and 30A. It shows an older style of trail building where rock walls were constructed (right side of trail) to hold in the trail tread against the slope (left side). This had the opposite of the intended effect where storm water would follow the same path and create even greater erosion. There are several trails in the park that have this old feature. Please consider volunteering if you would like to learn about modern trail building practices while mending these relics.

 

The Cheshire Quartzite trail tread profile disappears as it passes from Muddy and Rocky Ponds toward Proctor on the Carriage Trail. It also shows a drastic change moving toward the Redfield Trails. In fact, it is a striking coincidence that the boundary between the city-owned land of Pine Hill Park almost aligns perfectly with the bedrock boundary between the Cheshire Quartzite and the Dalton Formation. Perhaps it is not a coincidence. Maybe our ancestors noticed the difference in soil quality and divided the land as such?

Moving toward Proctor on the Redfield Trails and for a short distance past Muddy and Rocky Ponds you will find yourself on top of the Dalton Formation. The double- and single-track trail portions are relatively smooth while outcrops of rock similar to Cheshire Quartzite are visible. The Dalton Formation is a quartzite and parts of it look a lot like the Cheshire Quartzite closer to Rutland, but the rock is much older and it contains an important mineral called feldspar. This is the primary source for clay in soils around the world.

Where the Redfield Trails dip away to lower elevations of the Otter Creek Valley can also be explained by the the Ira Formation. This formation is composed of limestone and is much less resistant to weathering. For the full length of the Appalachian Mountains, limestone rocks underlie the valleys and quartz-rich rocks form the ridges and peaks. This is a persistent geologic pattern that largely controls the location of everything in our immediate surroundings.

Looking directly out from the overlook above Rocky Pond at the intersections of Shimmer, Overlook, and Stegosaurus Trails is Blueberry Hill, which is also capped by outcrops of Cheshire quartzite. In fact, several hills within the Valley of Vermont, such as nearby Cox Mountain and Bald Peak in Pittsford and Green Hill in Wallingford are also “held up” by the Cheshire Formation.

Moving toward Proctor as the Carriage Trail makes its descent off of the Dalton quartzite of Library Pass and across a short bit of the Ira limestone, is the Winooski Formation, which is a dolostone. This rock is a magnesium enriched limestone, which is easily weathered and provides a developed soil profile. In fact this can be seen in the very smooth final switchbacks of the singletrack that bring you down into town.

These lower elevations on the flanks of Pine Hill are also covered by a thicker layer of sediments from a river (aluvial), old lakes (lacustrine), and glacial moraines. The exception is where Cheshire outcrops occur along Grove Street. Some geologists hypothesize that there was an ice dam near the location of Evergreen Cemetery during the last glaciation, which is invoked to explain the extensive lake-derived clays found in the valleys.

The general point of this story is that geology explains much of what you see in terms of where trails have been located or sited, what maintenance practices are employed, and generally why we are such sticklers for details.

Please consider donating if you enjoyed this story and would like for us to continue stewarding this unique recreation resource.

Thank you Community Bank

Community Bank gave us a very nice contribution this spring. We used it to purchase materials to build two benches for the park. Thank you to Augie Levins who built the benches and to all the other volunteers that helped move them.

One is located on Underdog powerline and the other one is on Droopy Muffin powerline. We have several other locations we would like to install the same type bench in the future.

New Executive Director

For Immediate Release 10/12/2018
Contact Bryan Sell
Pine Hill Partnership Executive Director
pine.hill.bryan@gmail.com

The Pine Hill Partnership (PHP) announced that Bryan Sell (Mendon, VT) has been named Executive Director of the organization. PHP is responsible for creating and maintaining the trails in Rutland City’s Pine Hill Park and surrounding trail networks. Sell is PHP’s first executive director.

“We are very excited to have our first executive director,” said Andrew Shinn, President of the Pine Hill Partnership Board of Directors. “Bryan brings a wealth of outdoor knowledge to the organization, and just as important, he has a passion for mountain biking and trail advocacy.”

Bryan has been an avid mountain biker for 26 years and outdoor sports enthusiast for most of his life. He moved here a year and half ago with his family to take advantage of the outdoor recreation activities and culture that is unique to our region. He is married to Emily Feinberg, an ENT physician assistant at Rutland Regional, and has a son Hunter who is 4 years old; both are also very much into mountain biking.

Bryan’s work experience is diverse beginning with a stint in the U.S. Navy and then continuing his education while working as an Earth scientist in various capacities from drilling petroleum wells to working on ice cores for climate change research. Bryan has a PhD in geology from Syracuse University, is currently a part-time faculty member at Castleton University, and part-time snowboard/mountain bike instructor at Killington Resort.

Bryan joined the PHP Board in 2017 in an effort to build a trail from Rutland to Killington and was bamboozled into taking on other responsibilities. He has many years of informal trail building experience and became a student of sustainable trail building practices in 2015 while volunteering with a local International Mountain Biking Association (IMBA) chapter in Pennsylvania.

“I’m excited to plant solid roots in a great community and build something positive,” says Sell when asked about why he accepted the position. “My family spends a lot of time in Pine Hill, and I’ve spent my entire career devoted to the mountains and other landscapes. So it feels like a natural fit for me where I can bring all my passions together in one very special place.”

The Pine Hill Partnership is a non-profit formed in 2005 that has the mission of recruiting and organizing volunteers to repair, maintain and improve the non-motorized multi-use trail system in the city park at Pine Hill and adjacent lands. This past summer the Partnership hosted over 20,000 visits to Pine Hill Park.

IMBA National Award

RUTLAND’S SHELLEY LUTZ RECEIVES INTERNATIONAL MOUNTAIN BIKING ASSOCIATION VOLUNTEER OF THE YEAR AWARD

BENTONVILLE, Arkansas (Oct. 29, 2018) — The International Mountain Bicycling Association (IMBA) has presented Shelley Lutz (Center Rutland, Vt.) with the 2018  “Scott “Superman” Scudamore Volunteer Leadership Award” for her relentless and selfless service to her community. Lutz is one of the founding members of the Pine Hill Partnership and currently serves as the organization’s secretary.

The award honors outstanding volunteers who are making a significant contribution to the mountain bicycling community. IMBA received more than 20 nominations from all ten regions in the United States.

“I may seem biased when I say this, but I am continually learning that Shelley Lutz has done more for mountain biking in Vermont than any one person I’ve yet to meet,” said Bryan Sell, executive director of the Pine Hill Partnership. “She is the backbone of the trails in Pine Hill, which has achieved a cult-like status among mountain bikers and would not exist without her efforts.”

“Also, consider that growth in the sport is in no small part being driven by women and children, and Shelley has been a leader since the early days of mountain biking. Again, I do not know of any other woman who has done so much to get women and children pedaling on trails. I think that few of our residents appreciate how uncommon it is to see so many women and children on mountain bike trails, so this honor is as good for Rutland as it is for Shelley.”

Lutz has devoted thousands of hours to Pine Hill Partnership since the organization’s start in 2006. For over 25 years, she mountain biked, hiked, and skied in Pine Hill, and helped to layout, create, and maintain the trail network that we know today. In addition to trail work and organizing work days, Lutz has led a women’s mountain bike clinic and youth mountain bike clinic in Pine Hill Park for the past 10 years. She also has helped other trail advocacy groups in the region begin and grow their trail networks. Lutz exemplifies the Scott “Superman” Scudamore attitude of getting everyone she meets to volunteer in the Park.

Lutz has lived in the Rutland area since graduating from Castleton University in 1975. She worked for UPS for 36 years before retiring in 2011.

Scott “Superman Scud” Scudamore was a retired Air Force Captain who exemplified mountain bike volunteerism through his work with the Mid-Atlantic Off-Road Enthusiast.. Scud’s specialty was introducing new riders to mountain biking advocacy and to the efforts needed from local voices to ensure the sustainability of off-road trail networks to the growing population of outdoor enthusiasts.

Lutz was presented with the award at IMBA’s 30th anniversary party in Bentonville, Arkansas, on Saturday, October 27.
