Rummaging for History at Livermore Falls

Rummaging for History at Livermore Falls

Could You Imagine? Probably Not.

Could you imagine living in New Hampshire, pre-European contact? This is considered the Woodland era of Native American history. What would be the first thing you’d wake up and do in the morning - certainly not brew a cup of coffee with your Keurig appliance?  Also, our ancestors didn’t wake up and wonder if their friends posted about their breakfast again on Instagram. What did these early inhabitants have to wonder about?

Our ancestors had a very different culture compared to our modern day society.  Life was much more about survival and therefore depending on local natural resources. So, as much as we’d all like to live with a Chipotle Restaurant in our backyard, life was different for those who were very connected to their food sources.  . Compared to our modern society, where we can order almost anything online and have it delivered in two days using Amazon Prime. The indigenous inhabitants in what was the region of New Hampshire were hunter-gathers, fishers, trappers, and hunters. They had to find their own food, make their clothing and structures.   They had no choice but to live a subsistence lifestyle – existing primarily on what could be gathered from their immediate surroundings. Our role now, as a community, is to preserve evidence of their culture, found at Livermore Falls on the banks of the Pemigewasset River just upstream from Plymouth, found underneath later cultures who settled near the mills which provided energy to produce products.  The layers of archaeology at the site, thanks to the

State Conservation and Rescue Archaeology Program (SCRAP), are uncovering part of our heritage which we want to understand, preserve, and respect.  .

The Depth of History

Six Native Americans sites within the lowlands near Livermore Falls have been identified. At Livermore Falls there is a geologic fault where the river cascades down through tilted metaphorphic rocks into a big eddy pool below.  There is a one of a kind bridge spanning the gorge, the remains of a brick mill and stone foundations, walls, and cellar holes of earlier communities, and other historical records documenting the first fish hatchery in the state. In the last couple of years, 2016-2018, artifacts of these various cultures and earlier ones are surfacing thanks to archaeological digs commissioned as the state develops the scenic swimming hole into a state park and popular destination for the bordering towns of Plymouth, Holderness and Campton, NH (New England Waterfalls, 2016).

Three of the discovered sites contain cultural features from what is called the Archaic period (3000-1000 B.C.), and two more contain artifacts from the more recent Woodland period, (1000 B.C. to 900 A.D), (Gray & Pape, 2015).

The river not only provided drinking water, but good fishing for the Native Americans, whose camp sites would have been most active during salmon spawning. The early inhabitants recognized the need to move with their food sources and therefore had minimal belongings they could transport efficiently.  Out of all the interesting ecological, hydrological, topographical and geological characteristics where the river narrows at this location, those who followed, the early Euro-American settlers were most drawn to the waterpower of the falls

Around the late-1600’s, European arrivals developed more permanent settlements throughout New Hampshire, including at Livermore Falls. During this colonization period, the falls provided a power source for processing of grain and wool. The early mills later gave way to more industrial pursuits like pulp milling that served  markets outside  the local area, as shown in Figures 1 and 2 (Gray & Pape, 2015). The milling activity spawned the development of a community that came to be known as the “Hollow,” on the East bank of the river, downstream from the falls. The Hollow was comprised of numerous mills, a tannery, cobbler, blacksmith and New Hampshire’s first fish hatchery. However, the number of people residing at the site at any one time remains uncertain. As much bounty  as the river and falls  provided, flooding occasionally wiped  out human infrastructure in its path, but the settlers persisted and rebuilt until the State of New Hampshire acquired the property.

What’s Been Left Behind?

State archaeologists, David Trubey and Edna Feighner, have facilitated archaeologic digs around Livermore Falls during the summers 2016-2018, where their teams have uncovered Native American pottery (Figure 3), tool making debris, post-contact period glass, nails, buttons and clay pipes. As much fun as it is to collect historical artifacts, archaeologists are just as interested in understanding the people who made and owned the objects. Part of the archaeologic process involves decoding the events that occurred in the past. Both pre-European and the more recent post-European contact sites were buried by sediment from the dynamic river that still floods.  So, archaeologists had to systematically dig sample pits through the layers of deposited sediment. If they found something, then they knew where to concentrate their efforts to find more to begin the process of unraveling the chronology of the layered communities.

Today, a number of cellar holes from the Hollow period are exposed on site. Some of these rock foundations are remnants of past homes. Fieldwork revealed nine foundations on both sides of the Pemigewasset River, most are located within the Hollow found on the south-east side of the river. Records have revealed the area was an active industrial and residential site for nearly two hundred years. One after another, generations of mills operated and were eventually demolished due to fires and floods. Until archaeologists were hired to excavate the area to install recreational toilet facilities for the new park being developed, there wasn’t much above ground evidence left of the long history of settlements. After the archaeologists discovered evidence of earlier development on the site, they determined the need to create a history profile of Livermore. Additional support came from the Federal Emergency Management Agency (FEMA), who held an interest in providing funding for flood zone studies and was able to endorse the excavation during the summer of 2017.

A Student's Contribution

Visiting David and Edna in their archaeology lab in Concord, NH was like stepping back through time. Both were interested to talk about their discoveries and were clearly passionate about their jobs. Holding the artifacts felt like holding a baby – I didn’t want to pick them up too fast or accidentally drop and break them. The object shown in Figure 4 is an unknown tool used around the Hollow time period. From assessing the thin, hollow tool, we made a prediction that it might have been used for collecting medicine samples. One of the more interesting pieces, in my opinion, was a penny from 1860 engraved with Queen Elizabeth’s profile (Figure 5). More photos from the lab visit can be found at the end of this blog post.

Archaeology is a repetitive and rewarding process that requires patience.. Much time is spent scraping away the surface of the earth, screening the soil layer by layer, looking for samples, recording site details and assessing the artifacts.Excavation techniques are site-dependent and shovel test pits (50 cm x 50 cm) are dug along transects spaced 8 meters apart at Livermore Falls. Artifacts are mostly scattered within the A and B soil horizons most near the surface which show flooding and other land disturbances. A good indicator of a pre-contact site is a hearth comprised of fire-altered rocks and charcoal. For a post-contact site, a buried wall and stains in the soil from rotted wooden posts are strong indicators to keep digging!

One goal of archaeology is to preserve, conserve and engender respect for cultural history.  Imagine a future archaeologist, in the year 2600, digging up the area around Livermore Falls – what would he or she find? From the college students who visited, maybe a bunch of Juul pods and some Bud Light cans. If community members can recognize the connection between their current activities and what future historians will uncover, maybe they’ll think twice about what they leave behind. One can say learning the history of our communities in New Hampshire through archaeological digs and from other historical documents is integral to understanding ourselves.

Want to Dig Deeper into Livermore?

Join David and Edna on one of their upcoming archaeologic digs in Summer 2019! The two scientists will be leading a State Conservation and Rescue Archaeology Program (SCRAP) dig of the industrial area of Livermore Falls. Residents are welcomed to volunteer and students can participate for college credits.

Disclosure note:

As a responsible member of society, it is important to keep in mind that archaeological sites, including those found at Livermore State Forest, are nonrenewable resources. We have to be aware that these sites hold information from pre and post contact life can easily be lost forever.  As these sites are also a part of a NH State Forest, it is ILLEGAL to remove artifacts, dig or metal detect.  This is a place where good stewardship is necessary to preserve the landscape’s historical and natural features for future generations.

Livermore Falls: What's In Your Backyard?

Livermore Falls:  What's In Your Backyard?

By Jessica Casterline

View of Livermore Falls below.

Dynamic Tourist Site

Livermore Falls, located on the Pemigewasset River, is a dynamic tourist and educational site. Spend a day enjoying the sandy beaches, powerful waterfall, gorgeous rocks and deep clear water. Livermore Falls has everything you need to have a relaxing day. And, if you are interested in learning about the rich, colorful human and natural history, read more of the Livermore Falls blog posts produced by the environmental outreach and communication class at Plymouth State University. Offering diverse geology, hydrology, ecology, forestry, fishery and archeology stories, Livermore Falls has much to offer. .

This blog post is about the different habitats, wildlife and plants at Livermore Falls.

Presence of Poison Ivy

Let’s face it; many of us have had our run ins with poison ivy, but have you ever wondered if there are ecological benefits of the plants? Poison Ivy (Toxicodendron radicans) is actually vital to the environment and has several important roles. Poison ivy roots are like a spider web, only stronger. They hold the soil in place very effectively and prevent water and wind erosion. This is especially important near the Pemigewasset River, where floods occur. There are no dams in place above Livermore Falls, which increases the chance of floods. In addition to this ecosystem service, poison ivy produces a berry in the fall season. Many birds rely on the berry, and if you ever wondered how poison ivy spreads, you can now blame it on the birds.

There is an abundance of poison ivy at Livermore Falls, but do not let this scare you off! As long as you stay on the paths, you will not encounter poison ivy, but it is important to know it is there and how to identify it.

Myths Versus Facts

There are many myths about poison ivy; so let’s set the record straight. First and foremost, poison ivy, poison sumac and poison oak all have the same oil called “urushiol.” This oil is what gives people an allergic reaction, or rash.

  • Myth: Scratching Poison ivy blisters will spread the rash.

Fact: The fluid from your blisters will not spread the rash. The rash can only be spread by urushiol. That is why it is important to clean any infected area to remove the oil.

  • Myth: Poison ivy rashes are contagious.

Fact: The rash itself is not contagious, however if the oil is still on the infected area, it can easily spread the rash.

  • Myth: After an initial reaction, I cannot get a poison ivy rash ever again.

Fact: Although we wish this were true, it is not. People generally become more sensitized with each encounter and can therefore have worse reactions to poison ivy.

  • Myth: Once allergic, always allergic to poison ivy.

Fact: A person’s sensitivity changes over time. Sensitivity can even change from season to season. Just like any allergy, if you were allergic as a child, you may grow out of it as an adult, or experience worse cases.

  • Myth: Dead poison ivy plants are no longer toxic.

Fact: The oil, urushiol, can remain active on a surface for up to five years! Avoid handling dead poison ivy and wash any surface that comes in contact with it.

If you plan to spend time at Livermore Falls, or anywhere in the outdoors, it is important to be able to recognize poison ivy, poison sumac and poison oak. Poison ivy has 3 pointed leaves that are mostly green, but can also be red. The leaves are shiny, due to the urushiol. The plant can vary in form which means poison ivy can grow low to the ground, or as a vine high above your head. If you came in contact with one of the three plants, immediately wash the infected area with soap and water; the sooner the better! (Zanfel.com).

Rule of Thumb: Leaves of 3, Leave it be!

A diagram of how to identify poison ivy, poison oak and poison sumac. Notice how only poison ivy and poison oak have 3 leaves, while poison sumac has more.

Habitats

There are two main ecosystems at Livermore Falls: freshwater riverine, and forest habitats.

Native plants, such as blueberry, shadbush (also known as Juneberry) and elderberry exist at Livermore Falls. These plants provide food for deer, birds and black bears, that’s right bears! Bears have been spotted down stream from Livermore Falls enjoying the Pemigewasset River. You can also keep an eye out for North American beavers, otters, bullfrogs, snapping turtles, black ducks and salty skimmer dragonflies. Endangered birds can also be seen at Livermore Falls including:

  • Golden eagle

  • Upland sandpiper

  • Northern harrier

  • Sedge wren

          

  • Common Nighthawk

Also, look out for loons, bald eagles and peregrine falcons, who also depend on the Pemigewasset River for resources. (NHDES).

Conclusion

Livermore Falls is a compelling site for tourists or locals to learn more about the Pemigewasset River and surrounding forest ecosystems. Livermore Falls is also a great destination for outdoor recreation. It provides dynamic habitats and resources for all sorts of animals. Remember, this is a home to animals too, which is why it is important to leave the area clean and serene. It is vital to be respectful of Livermore Falls, so please abide by the rule: leave no trace.

Salmon be Dammed: Livermore Falls and the lost Atlantic Salmon

Salmon Be Dammed: Livermore Falls and the lost Atlantic Salmon

By Joshua Hoekwater, edited by Associate Professor Mary Ann McGarry

Salmon have long been a prized aspect of wildlife in North America and for many are regarded as the pinnacle of fishing and flavor. They are seen on almost any menu and have been glorified by artistic representations and cultures throughout time. Though how much do we know about the salmon we savor and adore?

The Evolution of Salmon Worship

 

In the coastal regions of America, Native American worship of salmon dates back thousands of years. Native American stories describe seemingly mythical salmon populations, that were so abundant, you could walk across the river on the backs of salmon during the spawning migration. This abundance made salmon a staple of tribal diets and is idolized in many traditions. The salmon spirit was used as an idol for guiding people to respect the ecological role of rivers and tributaries that salmon used to spawn. Each year, as salmon returned to the rivers, it was celebrated by the regional tribes and many performed ceremonies honoring this treasured resource.

However, as the Euro-American settlers started to arrive and develop the landscape, they also brought the beginning of the decline of the salmon. There were many factors that contributed to the development of these lands and the salmon decline, but by far the most continuously damaging change to the landscape was dams.

Dam FISH!

Salmon are an “anadromous” fish, which means that they migrate from the sea up into freshwater rivers to spawn. The blockage of rivers by dams means the loss of spawning habitat for anadromous fish and their inevitable decline. This story has played out many times in history, always ending the same way. In Europe, the agricultural revolution brought a dramatic change to the landscape. There many forests were logged and fields took their place and with these changes came agricultural watering systems and hydro-powered lumber/grain mills. These operations all rely on the damming of water for turning a water wheel, irrigating fields, or driving logs down river.

With these operations came a marked decline in salmon runs and the European governments and scientists took notice. The connection was quickly made that these dams were blocking salmon from moving upstream to their spawning grounds. European biologists were recommending that small gaps be made in dams in order for salmon to be able to pass, though little could be done to stop economic progress. Without these recommendations being enforced, dams continued to scatter the rivers and block salmon movement bit by bit until populations were considered, for practical purposes, gone. This same pattern has occurred in the eastern and western United States as the landscape was developed, but not all populations have been lost yet.

Today, dams are by far the most continuously damaging change to the landscape because they are absolute. What this means, is that when a dam is put up, it usually takes a seemingly extraordinary amount of effort and money to take them down or even modify them for fish passage. Many dams are absolute in the blockage of salmon, and can eliminate an entire watershed’s population if the dam is near the mouth of a river system. Dams are like no other changes to our rivers, because they are so complete in their elimination of salmon and absolute in their permanence.

 

 

 

 

 

The Loss of the Merrimack Salmon

In New Hampshire, the loss of the Atlantic Salmon in the Merrimack river is a local example of the dam issue that has been playing out across the world. Historic Atlantic Salmon populations no longer exist because of the many dams that now shape the Merrimack river. This is a common story in the Northeast, and wild populations of Atlantic Salmon now only exist in Maine and Canada. Without natural reproduction in the restricted rivers of the Northeast, fish hatcheries became a necessity. Hatcheries are an artificial solution that we originally hoped could help restore salmon populations. Instead, hatcheries are a tool for allowing us to go out and capture salmon that are stocked in lakes and ponds and it gives us that simulated feeling of a natural world.

The Livermore Falls area contains a relic of the first hatchery in New Hampshire. This hatchery is no longer functioning and the area has long since been abandoned by human occupants. The area serves as a reminder of the futility of raising salmon in hatcheries to then be cast into streams and lakes where a majority will die before they are ever seen. Restoring wild populations of salmon was the original goal of these hatcheries, but now that seems like a long lost dream. As a state routed in the ideology of “Live Free or Die” we ironically have accepted the world as it is and no longer question whether wild salmon could once again run in the rivers of New Hampshire and the Northeast. If enough dams in the Northeast were to be removed or modified as the infrastructure ages, maybe then we could revisit this long lost dream. For now, the Livermore Falls area offers a place to visit and contemplate permanence, as you watch the river flow over its famous falls in a lost village along the banks of a historic salmon river.
