Mink Brook & Tanzi Tract

DOWNLOAD FULL PDF OF DIRECTIONS – Mink Brook & Tanzi Tract

Driving directions:

  • From downtown Hanover, drive S on Main St. (Rte 10) 0.5 miles to Brook Rd.
  • Turn L just before Route 10 crosses Mink Brook.
  • Follow Brook Road for 0.1 mile to a sharp bend.
  • Park here near the trailhead gate.

What you should know:

  • Dogs are welcome but must be under close control (better yet, leashed); please pick up after your pet.
  • Foot travel only. Bicycles are not permitted in the Mink Brook Nature Preserve.
  • Trail maps are available at the trailhead kiosk near the Brook Road gate.
  • The Preserve is home to bears who may emerge from hibernation as early as March (another reason to leash your dog). If you encounter a bear, do not run but speak softly to it and move away slowly. Mother bears are as protective of their young as we are.
  • You will visit the 112-acre Mink Brook Nature Preserve, owned and managed by the Hanover Conservancy since 1999, and the 15.8 acre Angelo Tanzi Natural Area, owned by the Town of Hanover.

BRIEF HIKING DIRECTIONS

  • Take the Quinn Trail through the gate and visit the kiosk.
  • Continue on the Quinn Trail along the N side of Mink Brook, past the Norman Overlook.
  • Bear R to view the brook, then bear L to return to the Quinn Trail. Turn R and up the hill.
  • Enter the Tanzi Tract at a stone wall and turn R onto the Brook Loop. Follow back to Quinn Trail.
  • Cross the Quinn Trail onto the Forest Loop and return along the stone wall.
  • Turn R onto the Quinn Trail to return to your car.

FULL DIRECTIONS

  • Pass through the gate onto the Quinn Trail. Take a moment to check the kiosk display just ahead and pick up a trail guide. Note the map outlining Mink Brook’s 18.5 square mile watershed.
  • Hanover’s largest stream begins high on Moose Mountain at Mill Pond, gathering waters from other headwater streams and flowing through Etna, where it once powered so many mills that the village was first known as Mill Village. Below Etna, the brook turns and runs S of Greensboro Road through the Mink Brook Community Forest, protected in 2021. Crossing under Route 120 and past the remains of a mill built for Eleazar Wheelock, the brook rushes W past the Tanzi Tract and through the Mink Brook Nature Preserve toward the Connecticut River.
  • You are walking the easy, flat Quinn Trail, named for a Hanover family we’ll hear about later. This part of the trail follows a buried sewer line marked by covers labeled “Hanover Sewer 1976.” While they seem out of place on a woodland walk, we can forgive the intrusion since the building of this sewer line to collect waste from hundreds of Hanover homes meant the transformation of Mink Brook and the Connecticut River from noxious open sewers back to the safe, clean waters they are today.
  • Note the nature of the water in the brook. If ice-free, does it appear to be lazy and slow-moving, or is it locked silent under a cover of snow and ice? In this area, both the Connecticut and Mink Brook are pond-like, backed up behind Wilder Dam just downstream in Lebanon. Farther along the trail, stay alert for a change in character to the naturally free-flowing, musical stream that flows off the uplands.
  • 5 minutes’ walk from the gate, the trail takes a sharp L by a crabapple tree. Pause here to note the thick, ropy stems of river grape (Vitis riparia) growing up the trees at L. This native vine is common along streams and offers a rich food source for birds and other wildlife.
  • Now look R for a path heading towards the brook through young pines, and take a short trip down to the water where stepping stones offer a way to cross the brook at certain seasons. In the 1990s, a 30+ lot subdivision was laid out for the 112 acres of today’s Preserve. A road to serve the subdivision was to cross the brook here. Give a cheer for the 500 donors, the Quinn Family, and Dartmouth College for recognizing the natural value of this place and stepping up to help the Conservancy and Upper Valley Land Trust protect it. The Hanover Conservancy now owns and manages the land, with conservation deed restrictions from UVLT.
  • Return to the Quinn Trail and note the exposed roots of a large tree on the steep bank opposite. This clay bank was mined at one time for clay that was used to build Dartmouth’s tennis courts!
  • Turn R to continue on the Quinn Trail; you’ll soon arrive at the Norman Overlook at R, marked by slabs of granite offering a pleasant perch for observing the brook. Bob Norman, a founder of the Hanover Conservancy in 1961, was its President in 1999 when the Preserve was protected. A demonstration planting of native shrubs includes red osier (Cornus sericea), whose brilliant red stems are especially ornamental in late winter. This handsome shrub is a great choice for wet areas, as it tolerates wet feet and its white berries offer high quality food for wildlife in fall. You may see it growing naturally nearby.
  • At this point, the brook is clearly more lively, with patches of open water roiled by its flow. Wilder Dam may be far out of sight, but it controls the character and movement of Mink Brook here in the Preserve and of other tributaries as far north as Haverhill NH and Newbury VT, 45 miles upstream. The Hanover Conservancy is closely following re-licensing of this dam and studies of how it affects erosion and sedimentation, fish, wildlife, invasive species, and even archeological sites. As this hike is published, a welcome new proposal from the hydropower company suggests altering dam management to more of a natural, run-of-river flow than an up-and-down “peaking” flow, meaning that more of Mink Brook would be allowed to behave like a proper stream instead of a pond.
  • Note the stone riprap on the streambank near the tree line. Tropical Storm Irene sent so much water down Mink Brook that the brook changed course and began to erode this bank. Because the sewer line runs close by, the Town of Hanover is intervening to protect it from erosion.
  • Just past this site, bear R off the Quinn Trail toward the old log crossing. The beautiful log bridge, crafted in 2009 from a nearby tree, served for over a decade to connect trails on the north and south sides of the Preserve. Mother Nature began to reclaim it and the crossing was closed in August, 2021 for public safety. From this point you can still enjoy views of the brook and a distinctive square-topped stone.
  • Follow the path, bearing L at a fork to return up a short narrow path to rejoin the Quinn Trail. Turn R and take care on the stony slope as you approach the pine and hemlock forest on the hill above.
  • Note the plaque at R honoring the Quinn Family, who helped protect this land in 1999. Both Brian and Allie Quinn were members of the Conservancy’s board of directors, with Allie leading environmental education efforts in Hanover schools in the 1970s and 80s.
  • 5 minutes’ walk from the brook, arrive at a mossy stone wall marking the boundary with the Tanzi Tract. In 1966-67, working with the newly formed Conservation Commission, the Conservancy took an option on this 15.8 acre parcel and provided half the funding for its purchase for the Town. Angelo Tanzi (1899-1969) was a beloved local figure who managed a grocery market on Main Street (R), and whose family once owned this land.
  • Turn R to follow the Brook Loop for a few minutes along the stone wall to a lookout over a particularly pretty section of Mink Brook.
  • The Brook Loop bends left past a private inholding and returns in a few minutes’ walk to the Quinn Trail. Cross it to explore the 10-minute Forest Loop, marked “Foot Trail Only.”
  • Soon, a wooded slope looms up ahead – one of the strangely steep sides of ancient channels of Mink Brook. This region was once inundated by the frigid waters of glacial Lake Hitchcock. Its fine sediments were easily sliced by the rushing waters of such brooks after the lake receded, leaving these ravines. The Storrs Road neighborhood, up out of sight on the terrace above, is set on part of the old lake bottom.
  • The Forest Loop follows the base of the slope, bending L and passing over two boardwalks through great bear territory. In the hollow is a beautiful forested wetland that begins to hum with life in early spring. Note evergreen Christmas ferns and tipped-up trees in the wet soils.
  • High quality habitat abounds here, for bears, wood frogs, and many other creatures and plants. In fact, the NH Fish and Game Department’s Wildlife Action Plan identifies this area as some of the highest quality habitat in the state, shown in pink on this map.
  • The stone wall soon reappears at R. Keep a lookout for an old pine snag that gives an up-close-and-personal view of pine anatomy, branch collars and all.
  • Return to the Quinn Trail and the Mink Brook Nature Preserve boundary sign on a large pine. Turn R and follow the trail down the hill, watching your footing and taking no turns.
  • At the foot of the hill, the path may be damp with drainage from a wetland that is an extension of the one you skirted on the Forest Loop. This space is lively in spring with wood frogs and other amphibians courting and laying eggs.
  • Continue W on the Quinn Trail past the Norman Overlook and kiosk to return to your car. As you do, note the change in character of the brook as it shifts from a free-flowing stream to one whose flow is captured by Wilder Dam.
  • Be sure to come back as spring unfurls at the Preserve. This is a great walk at any time of year.

Driving directions:

  • From downtown Hanover, drive south on Main Street (Route 10) 0.5 miles
  • Cross the bridge over Mink Brook
  • Turn R into Pine Grove Cemetery and park.
  • Walk across Route 10 to begin your hike.

What you should know:

  • Dogs are welcome but must be under close control (better yet, leashed); please pick up after your pet.
  • Foot travel only. Bicycles are not permitted in the Mink Brook Nature Preserve.
  • Trail maps are posted at trail junctions and are available at the trailhead kiosk near the Brook Road gate.
  • The Preserve is home to bears who may emerge from hibernation as early as March (another reason to leash your dog). If you encounter a bear, do not run but speak softly to it and move away slowly. Mother bears are as protective of their young as we are.
  • After crossing a small town-owned space next to Route 10, you will visit the 112-acre Mink Brook Nature Preserve, owned and managed by the Hanover Conservancy since 1999.

BRIEF HIKING DIRECTIONS

  • Take the Wheelock Trail along the S side of Mink Brook.
  • Continue past the old log crossing to a group of large boulders.
  • Return past the log crossing on the Wheelock Trail.
  • After the Wheelock Trail turns L, bear L onto the Trout Brook Trail.
  • Bear R onto the Mink Link across a set of bog bridges.
  • The Mink Link meets the Sachem Connector at Trout Brook.
  • Turn R onto the Sachem Connector and L onto the Wheelock Trail.
  • Stay on the Wheelock Trail to return to your car.

FULL DIRECTIONS

  • Begin your hike by walking through the open area toward a telephone pole visible ahead on the easy, flat Wheelock Trail, named for Dartmouth’s founder. This land and a mill privilege just upstream on Mink Brook were offered to Eleazar Wheelock as an incentive to locate his new college in Hanover.
  • You’ll soon encounter a Hanover Conservancy sign as the trail heads into the woods. A smaller sign reminds that bicycles are not permitted on the Preserve, a condition of the generous gifts that made purchase of the land possible.
  • The trail enters the woods and 5 minutes from the road, passes through a natural gate of two impressively large (for them) musclewood trees (R). A look at their limbs hints at the reason for this odd name – they look like they’ve been to the gym!
  • The blue-blazed trail passes briefly under a power line and then through a richly mixed hardwood forest.
  • 4 minutes from the musclewood gate, look for a large multi-stemmed cherry tree at L. Bear L at a Y here, where a private trail enters at R. The Wheelock Trail traverses Mink Brook’s flat floodplain.
  • 2 minutes later, a pair of logs takes you across Trout Brook. This stream rises in Lebanon and flows north to meet Mink Brook. It might not look like much here, but in its upper reaches on the Preserve it provides very high quality habitat for (albeit small) wild brook trout, here almost within sight of downtown Hanover.
  • 4 minutes later, the trail rises to a junction with the Sachem Connector, a red-blazed trail at R. You’ll return on that path. For now, stay L among the big pines.
  • You’ll soon cross a small drainage on a series of stepping stones. Just beyond is the junction of the orange-blazed Trout Brook Trail. You bear L to stay on the blue-blazed Wheelock Trail.
  • A few steps further, at a big double pine, the Wheelock Trail turns R. A spur trail at L leads to stepping stones across Mink Brook to the N side of the Preserve. This is where a bridge was planned to serve a proposed 32-lot residential subdivision in the area you’ve been exploring. Give a cheer for the 500 donors, the Quinn Family, and Dartmouth College for recognizing the natural value of this place and stepping up to help the Conservancy and Upper Valley Land Trust protect it. The Hanover Conservancy now owns and manages the land, with conservation deed restrictions from UVLT.
  • Continue E on the Wheelock Trail for a few minutes to the former log crossing. Crafted in 2009 from a nearby tree, it served as a temporary trail link until the fall of 2021. A replacement crossing is planned. A sign on a tree opposite the log crossing directs you to continue E on the Wheelock Trail toward Buck Road. We’ll turn around well before that, but recommend that route for a summer’s day. Note an island in the brook on your L; until Tropical Storm Irene came through in 2011, Mink Brook flowed mostly between the path you’re on and this island. High water caused the brook to change course to the far side of the island, and this area is wet only a few times each year. Brooks are dynamic!
  • Continue to follow the brook upstream through deepening hemlock and pine forest.
  • 3 minutes’ walk from the log crossing, note a large, flat-faced stone ahead at R. Stop and look more closely – a jumble of large stones nearby appear to have been placed a very long time ago – but by whom?
  • Watch your footing as the trail bears L among boulders, ledges, and roots, past an ambitious hemlock growing over a low stone wall.
  • The most massive stone of all rears up at L. Follow the trail up a few yards to a nearby lookout above a small waterfall on Mink Brook. You have reached your destination.
  • These silent stones clearly have stories to tell. We don’t know what the stones might say, but in our imaginations, they must be eloquent – they are the original and timeless inhabitants of this beautiful stream valley.
  • Through the millennia Mink Brook, or Mosbasak Zibosiz in the Abenaki language, has been a key part of local Abenaki village and subsistence grounds. From the time of Dartmouth’s founding, Abenaki and other Native families lived in this area to support their children who were enrolled in Moor’s Charity School and the College. Abenaki families have lived nearby to this day.  What is known today as the Mink Brook Nature Preserve has long been known as a “woman’s place,” and when Eleazar Wheelock arrived to raise his college, Abenaki grandmothers met with his people to lay out their expectations for how the land would be used.
  • It’s hard to imagine this place as a residential subdivision and yourself standing amid driveways, garages, mailboxes, landscaped yards, and houses with dogs and cats. Turn your thoughts instead to the public-spirited vision of those who worked to protect this place so the stones could continue to speak to all.
  • After visiting with the stream and the stones, retrace your steps past a glistening yellow birch and head W on the Wheelock Trail. Pass the old log crossing and bear L at the forked pine, leaving the brook behind.
  • In a few paces, reach the junction with the orange-blazed Trout Brook Trail. Bear L here, following the little rivulet upstream.
  • In 2 minutes’ walk, pass a big rock at R and arrive at another trail fork marked with a “no bikes” sign. Bear R onto the Mink Link. Cross the wetland here on a new bog bridge.
  • This crossing and another you’ll soon encounter were built in 2019 by Andrew Chen of Troop 45 for his Eagle Scout Project. The task was to create a dry crossing of split and peeled hemlock logs through a wetland that had been trampled by hikers making an informal shortcut. With the bog bridge in place, the wetland has recovered well. An incredible 176 hours went into this project. The Hanover Lions Club and the Rankin family contributed to the cost of materials. Thanks to all!
  • The Mink Link Trail moseys up and among the hemlocks and pines, soon reaching another of Andrew’s log crossings. Note a posted map at L marking the junction of the Mink Link and Sachem Connector. Hop up on the bridge, which crosses Trout Brook.
  • Andrew’s bridge replaces another one that previously washed away in high water. Does the tame little stream you’re viewing today seem capable of such a feat? Had this land not been protected and the area altered with construction of roofs, driveways, and other surfaces that would prevent rain from soaking into the ground, this brook could have become downright dangerous during the heavy storms now associated with climate change. Now, a thick forest canopy and a blanket of natural duff over the soil act as a sponge to let the water flow more slowly and with less force when the hard rains come.
  • Return to the trail sign and bear L to take the Sachem Connector Trail up and around a small knoll. The trail is blazed red, but you won’t see the next blaze until you’ve gone around the bend.
  • 10 minutes from the Trout Brook Trail, you return to the Wheelock Trail amid some impressively tall pines. Bear L at a Y around two of them.
  • You’ve just passed most of the way around one of many oddly steep ridges that mark the sides of ancient channels of Mink Brook. This region was once inundated by the frigid waters of glacial Lake Hitchcock, and the clay/silt lake-bottom sediments were easily sliced by the rushing waters of the brook after the lake receded, leaving steep-sided ravines.
  • 3 minutes later, cross Trout Brook again. Just a few yards beyond, note two large “basket ash” trees, one on either side of the trail. These are a species of ash with pale, finely flaked bark that are favored for the making of baskets by Native American craftspeople.
  • Bear R at the many-stemmed cherry tree to avoid the neighborhood trail at L.
  • 9 minutes from your last crossing of Trout Brook, arrive back at your car. Resolve to return as spring unfurls at Mink Brook. This is a great walk at any time of year.

 Note: The Hanover Conservancy seeks volunteers to monitor trails and help out with occasional work parties. We also warmly welcome donations to our Mink Brook Stewardship Fund to help maintain the Preserve.  Get in touch at info@hanoverconservancy.org.

Mink Brook Community Forest PROTECTED!

We are thrilled to announce that the 250-acre Mink Brook Community Forest (formerly owned by the Leavitt family) off Greensboro Road is now permanently protected and open to the public! An entire generation of conservationists worked to make this project happen: read the full press release here. 

This couldn’t have happened without The Town of Hanover and the Trust for Public Lands working in tandem with generous local donors- thank you all! The Mink Brook Community Forest belongs to the Town of Hanover and will be managed for sustainable forestry, low-impact recreation and biodiversity.

The land is now open to the public. Keep an eye out for guided hikes to the property, to be announced soon!

 

Limited guided hikes at the future Mink Brook Community Forest

Join the Town of Hanover and the Hanover Conservancy this fall for a limited series of guided hikes at the future Mink Brook Community Forest on Greensboro Road. Hikes will be offered every Tuesday between September 15th and October 13th, with rain dates on Thursdays. Strenuous, off-trail hikes will alternate to the north and south parcels each week at 9 a.m., with a gentle meadow walk every week at noon.

Note: No public access is permitted outside of the scheduled guided walks.

Pre-registration required; group size limited to 10 people (leader plus 9).

Learn more and register here. 

We’ve got mail!

Wooden mailbox on the summit of Balch Hill This fun mailbox on the summit of Balch Hill is filled with pens and postcards so visitors can write a note with their favorite memories of this natural area, whose summit we protected 50 years ago.

Some notes so far: “I am 7 1/2 years old and my Dad brought me here today for the first time! Thank you for keeping this place open. I love the butterflies.”

“This hike is magical. I do it weekly. We are privileged to life in such a beautiful place as this.”
