For generations, Pennsylvanians have been at the forefront of conservation movements that have shaped the United States. Pennsylvanians like Gifford Pinchot, Joseph Rothrock, J Horace McFarland and Rachel Carson have had immeasurable impacts on our natural world. 

They’ve helped protect our forests, create state parks, beautify our cities and warn against the devastating affects of pesticides. Others like Ralph Brock and Mira Lloyd Dock have often been left out of the history books, due to discrimination. But finally, they voices and work are being raised up.

From the indigenous tribes that inhabited the lands we now call Pennsylvania, to the activists that helped pass the environmental rights amendment to our constitution, Pennsylvania has a long and storied history of conservation. 

I find that the more time I spend outside enjoying our incredible public lands, the more I want to learn more about our history of conservation. But where’s a good place to start? Where can I learn a lot without getting bogged down in timelines and jargon.

For me, there’s been no better guidebook, than Allen Dieterich-Ward’s "Cradle of Conservation: An Environmental History of Pennsylvania."

Released in 2024, this book is a comprehensive study of Pennsylvania’s environmental history in less than 150 pages. This concise book unpacks the people, policies and pivotal moments that turned Pennsylvania into a leader in conservation. Whether you're a history buff, a nature lover, or just someone who enjoys a good story about the great outdoors, this book is for you.

On this episode, I speak with Allen Dieterich-Ward. Allen is a professor of history and director of The Graduate School at Shippensburg University and the author of Cradle of Conservation.

When taking a hike, people don’t often think about everything it takes to keep trails operational. The bridge building, the trail restoration, the habitat enhancement, the invasive species management and so on. The work often goes unseen. 

And if you don’t spend much time thinking about the work that takes place, even less time is spent thinking about the people that do the work. The image of burly guys in flannel with hardhats and chainsaws come to mind. Rough and tough individuals who would have been lumberjacks or coal miners in previous generations. Now, wearing safety orange they tend to the land for the benefit of all Pennsylvanians. 

Yeah. That’s just not the case. While many of those guys and gals are still out there performing the work, often time projects are being done by kids. Well not kids, kids but young adults ages 15 to 25. 

Members of the Pennsylvania Outdoor Corps take on projects across dozens of state parks and forests every year through programs lasting 6 weeks to nine months. Mentored by older individuals, these crews complete tens of thousands of hours of work on improvement projects while also receiving training and education and developing team building and career opportunities.

The Pennsylvania Outdoor Corps was created by DCNR Sec. Cindy Adams Dunn to connect youth and young adults with job opportunities relating to the outdoors and the environment. 

On this episode, we’re going to be exploring the work they do, their service to the Commonwealth and the careers that come from working in the Pennsylvania Outdoor Corps.

On this episode, I speak with Michael Piaskowski. Mike is the manger of the Pennsylvania Outdoor Corps.

It’s 1910 and Anthony Wayne Cook has just inherited his family’s land. Over the last 80 years, the Cook family had made their money off the land. It started with his grandfather John Cook - who purchased the land in 1828. He built a sawmill on the property to process the timber he was harvesting from the forest. 

Andrew Cook – Anthony’s father - would go on to build three sawmills, one flouring mill, one planning mill, a boat scaffold, several dwellings and a store on the property. While much of the beautiful landscape had been forested, some of the most stunning examples of ancient forests remained. 

Andrew passes away in 1891 and now it’s Anthony’s turn to take over the family business. But he had plans of his own. Anthony Cook wanted to preserve the 300-year-old towering hemlocks on his land for future generations. He wanted everyone to sit at the alter of the so-called “Forest Cathedral.” 

Over the next 16 years, Anthony Cook and others campaigned to preserve this magnificent landscape. In the 1920s, the Cook Forest Association was formed to save the few areas of surviving old growth timber.

Endorsed by national natural resource groups and Governor Gifford Pinchot, the association raised $200,000, which helped the commonwealth purchase 6,055 acres from A. Cook Sons Company in 1927 for $640,000.

Cook Forest became the first Pennsylvania state park acquired to preserve a natural area and was later designated a National Natural Landmark. 

Now, we have the Cook Forest State Park. with its 11 different old growth forest areas. It’s been called “The Best Old-Growth Forest” in America.

On this episode, I speak with Dale Luthringer. Dale is the environmental educational specialist at Cook Forest State Park.

In the 1930s, a beautiful forest in northeast Pennsylvania was set to become a national park. Which made sense. The area was special, even to those that purchased the land to timber it.

In a time when forests across the Commonwealth were being clear cut to feed the growing nation of raw materials, this forest received some reprieve. As a result, 300-year-old trees were allowed to continue to grow – providing the forest with mature trees and the viewing public with examples of ancient forests.

These magnificent trees stood 100-feet tall with diameters of almost four feet. But between these arboreal giants hid a collection of natural wonders found nowhere else in Pennsylvania. 

Two creek branches cut through deep gorges creating a series of unbelievable waterfalls. These waterfalls united and flowed through a glen among massive pines, hemlocks and oaks. 

Unfortunately, World War II brought an end to the plan to make it a national park. However, thousands of acres were purchased in the 1940s to preserve this incredible landscape and its otherworldly glens. 

In 1969, the glens became a registered National Natural Landmark and was later made a State Park Natural Area in 1993. We now know this property as Ricketts Glen State Park. 

Ricketts Glen reminds me of a quote I once heard. "And into the forest I go, to lose my mind and find my soul." That’s how many feel when they visit this special place. That is, if the park isn’t filled with other people trying to do the same thing. 

On this episode, I speak with Scott Wilson. Scott is the manager of the Ricketts Glen State Park.

Welcome, fellow explorers. My name is Christian Alexandersen and I’m the host of Hemlocks to Hellbenders, a podcast highlighting Pennsylvania’s parks, forests and great outdoors.

We have an incredible lineup of parks, forests, guests and topics that we will be exploring during our third season in 2025. Park and forest managers, outdoor educators, historians, authors, conservationists and recreationalists are just some of the guests that will be sharing their passion and expertise with us this season. 

The topics that’ll be discussed cover a wide range of areas including outdoor recreation, conservation, historical figures, indigenous peoples, backpacking, plant and wildlife management, volunteerism and so much more.

If you love discovering Pennsylvania’s wonderful natural habitats, this is the podcast for you. We’ll help you plan trips and find hidden gems throughout Pennsylvania’s stunning public lands. 

I created Hemlocks to Hellbenders in 2023 to inspire listeners to spend time in Pennsylvania’s parks and forests, to advocate for their preservation and to make the outdoors a more welcoming place for everyone. We hope you’ll join us in that mission.

I’m also excited to announce that we have four sponsors for our third season – the Keystone Trails Association, Purple Lizard, the Pennsylvania Parks and Forests Foundations and Sisters’ Sunflowers. You’re going to be learning about their awesome services and products throughout the year.

Our third season kicks off on Jan. 1 with an episode on Ricketts Glen State Park – Pennsylvania’s waterfall oasis. I look forward to sharing our new guests and episodes with you in 2025.

In September of 2022 before leaving office, then Gov. Tom Wolf announced the creation of three new state parks. Susquehanna Riverlands in York County, Big Elk Creek in Chester County and Vosburg Neck in Wyoming County. 

While these new state parks were quickly opened following the announcement, they have not taken their final form. Before they can be completed – or really before they even start – these parks must go through a rigorous master planning process with numerous phases. 

There’s the planning phase, the design phase, the engineering phase and the construction phase. But in between those phases and additional processes, the Pennsylvania Department of Conservation and Natural Resources must seek public input, hold public forums and receive feedback from various stakeholders. 

The opening of the state parks to the public was the easy part. But, now’s the hard part. The amount of questions that must be answered and properly addressed can be stagging. 

Our season finale is meant to let listeners know when the various phases will be complete, what sort of activities and camping options will be available and what the future holds for our three newest parks. And for this large task I wanted to go straight to the source. 

On this episode, I speak with John Hallas. John is Director of Pennsylvania’s Bureau of State Parks.

In the early 20th Century, Americans had become alarmed at the disappearing forests in the eastern United States. Whether through private land purchases, deforestation, mining or other activities, the beautiful forests of the east were vanishing.

Where once stood primeval forests of giant eastern hemlocks now stood stumps. As a result, wildfires spread through these devastated lands. Waterways were polluted. And little of Penn’s Woods remained. 

Thankfully, lawmakers listened to the alarm bells of conservationists and in 1911 passed the Weeks Act. Name after Massachusetts Congressman John Weeks, the legislation allowed the use of federal funding to purchase forest land for conservation in the eastern United States.

The legislation – which was signed into law by President Howard Taft -- is one of the most successful land conservation efforts in United States history. And, it was thanks to this law that we have the Allegheny National Forest.

Created in 1923, the Allegheny National Forest spans over half a million acres in northwestern Pennsylvania. The sheer size of the forest is incredible. At just over 800 square miles, the national forest is over three quarters the land size of Rhode Island. 77.5 percent, actually.

This spectacular piece of public land offers a sanctuary for outdoor adventurers, wildlife lovers and history buffs alike. Whether you’re seeking the thrill of hiking over 200 miles of trails, the serenity of fishing in pristine lakes or the majesty of the towering trees and diverse wildlife, this forest has something for everyone.

On this episode, I speak with Jamie Feikles. Jamie is the Recreation Program Manager at Allegheny National Forest.

On this – the Halloween episode – of the podcast, we’re going to be exploring the many tales of ghosts, creatures, hauntings, cryptid sightings, unexplained phenomenon, legends and folk tales that have a history in Pennsylvania’s parks and forests.

From the ghost sightings at Greenwood Furnace State Park to the Kecksburg UFO incident in Forbes State Forest, we’re going to be hearing stories and sometimes first-hand accounts of frightening events from over the years.  

These sorts of stories have always held a special place in my heart. When I was a bored teenager looking to escape my dull suburban hometown, I’d load up my car with friends at night and go exploring. The latest copy of Weird New Jersey in hand, we’d go to cemeteries, abandoned hospitals and all manner of supposedly haunted places looking for something, anything, that would scare us.

That tradition – known as legend tripping – is as popular today as it was when I was growing up 20 years ago. Teenagers – and plenty of adults - are looking to stories of the past to fill their lives with a little bit of mystery. And in a place as big and as diverse as Pennsylvania, there’s plenty stories that’ll make your hair stand up. 

Whether you're a skeptic or a believer, these tales will leave you questioning the boundaries of reality and wondering what might be hiding just out of sight, right here in Pennsylvania.

Our guides for this journey are Brendon Perry and Nic Pennsylvania, hosts of The Ghost Furnace Podcast.

Those visiting Hickory Run State Park in the Pocono Mountains should expect to see something they’ve never see before. In the northeast corner of the park, formed by millions of years of glacial movement is the Boulder Field. 

At 400 feet by 1,800 feet, this vast, rocky landscape is a geological marvel. The field is made up of tightly packed sandstone boulders, ranging in size from small stones to massive rocks that weigh several tons. Some of the boulders are 26 feet long.

The Boulder Field’s appearance is striking because of its flatness and the absence of vegetation over the large area. It looks like something you’d on the moon or some distant planet. 

The site was formed over 20,000 years ago during the last Ice Age, when repeated freeze-thaw cycles caused the sandstone to fracture and break apart, leaving behind this stunning rocky expanse.

Because of its preserved state, the Boulder Field offers a rare glimpse into the geological processes that shaped northeastern Pennsylvania. This National Natural Landmark begs to be explored by those visiting the park. 

On this episode, I speak with Megan Fedor and Jake Smith. Megan and Jake are environmental education specialists at Hickory Run State Park.

There’s just something about mushrooms that so are cool. I can’t really explain it. They come in all shapes, sizes, and colors, often looking like they belong in a fairy tale or another planet.

They transform any landscape with their mysterious, almost magical appearance. They are not plants or animals but belong to a fascinating kingdom of their own. They thrive in the most unexpected places. They can taste delicious or they can kill you.

They’re just awesome. But developing a hobby in mycology can seem a bit daunting for a beginner. There are thousands of mushroom species, and many look similar, making it difficult to identify them accurately. Some edible mushrooms have toxic look-alikes, so learning the differences requires careful study.

Luckily, there are groups out there to welcome beginners to this great hobby. The Philadelphia Mycology Club is one such group. Founded in 2018, the club includes a diverse group of novice and experienced mycophiles. 

On this episode, I speak with Sam Bucciarelli. Sam is the president of the Philadelphia Mycology Club.
