Hundreds of years ago, a group of Native Americans living along the lower Susquehanna River made an indelible mark on the valley. At what is now known as Safe Harbor, they made hundreds of carvings into the rocks found in the middle of the river.

Animals, bird and animal tracks, directional symbols, teaching or storytelling images, humans and anthropomorphic images, spiritual symbols and geometric and abstract designs were painstakingly carved into the boulder strewn landscape of the river. From the banks of the river, the sites look like any of the rocks found in the river. But up close, these stunning petroglyphs offer a window into a fascinating culture that we still know very little about.

Despite Native Americans being driven from their homes, villages and hunting grounds. Despite countless floods. Despite dam construction. Despite pollution. Despite industry. And despite man’s constant need to exert his will over the river, these magnificent petroglyphs remain.

Big Indian Rock. Little Indian Rock. Circle Rock. Turkey Track Rock. Eagle Rock and Conestoga Rock.

Right in the middle of the Susquehanna River, as they have for hundreds of years. These sites are sacred spaces for Native Americans. The Safe Harbor Petroglyphs are a rare, direct connection to Indigenous peoples who lived along the Susquehanna River long before European contact.

For many Native communities, these carvings are not just historical artifacts but living cultural expressions—messages left by ancestors that carry spiritual meaning. Their location along the river, a vital life-giving force, further reinforces their sacred nature as places of reverence, storytelling and ancestral presence.

And unlike many pieces of indigenous rock art, they are accessible to the public. But that accessibility comes with a responsibility.

These carvings are irreplaceable cultural and spiritual expressions created by Indigenous peoples, and even small actions—touching the rock, climbing on it, or disturbing the surrounding area—can cause permanent damage.

Visitors also have a responsibility to listen and learn. Approaching the petroglyphs with humility means acknowledging that this site holds meaning far deeper than what we may fully understand, and that it represents living cultures whose histories and voices have too often been ignored or erased.

On this episode, I speak with Paul Nevin. Paul is recognized as the leading authority of rock art of the lower Susquehanna River and is the author of the “A Guide to the Safe Harbor Petroglyphs.”

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.

Season four of Hemlocks to Hellbenders is shaping up to be our most exciting yet and I can’t wait to take you along for the journey in 2026. We’ll be exploring some of Pennsylvania’s most incredible parks and forests with the people who know them best: park and forest managers, outdoor educators, historians, authors, conservationists and volunteers who are deeply passionate about this place we call home.

This season, conversations will range from outdoor recreation and backpacking to conservation, wildlife and plant management, Indigenous history, volunteerism, and the stories of the people who shaped Pennsylvania’s landscapes.

If exploring wild places, learning their stories, and planning your next adventure excites you, you’re in the right place. Together, we’ll dig into hidden gems and help you experience Pennsylvania’s public lands in a deeper, more meaningful way.

I launched Hemlocks to Hellbenders in 2023 to inspire people to spend more time in Pennsylvania’s parks and forests, to stand up for their protection, and to help make the outdoors a more welcoming place for everyone. I hope you’ll join us in that mission.

I’m excited to be bringing back four advertisers for the 2026 season; the Keystone Trails Association, Pennsylvania Parks and Forests Foundation, Purple Lizard Maps and Sisters' Sunflowers. And I’m thrilled to announce two new supporters of the podcast, Discover Clarion County and Go Laurel Highlands.

Our fourth season kicks off on Jan. 7 with an episode on the Native American rock carvings found in Safe Harbor on the Susquehanna River. I look forward to sharing our new guests and episodes with you in 2026.

For a long time, there’s been this mostly unspoken rule that “real” outdoor experiences have to be rugged. You’ve got to rough it, hike ten miles in the rain, sleep on the ground and eat beans from a can — or else it somehow doesn’t count.

Luckily, that’s changing. More and more people are discovering that you don’t have to give up comfort to connect with the outdoors. Here in Pennsylvania – especially in state parks - that change has been evident. Instead of only offering tent sites, state parks have cottages, cabins, yurts and other accommodations. Many offer amenities like stoves, refrigerators, microwaves, tables and chairs.

No longer are you forced to pack up everything you own for a weekend in the woods. You can book a comfortable accommodation AND still be in nature. However, these upgraded accommodations still have rubbed people the wrong way.

It isn’t “real’ camping. What does that even mean anyway? Real camping? Does it mean sleeping on the ground. Waking up with a sore back and condensation in the tent. Cold and miserable. No thanks.

It’s that sort of attitude that I despise in the outdoors. You’re not a real hiker unless. You’re not a real hunter unless. You’re not really camping unless. It’s such a pointless and divisive way of thinking.

Thankfully, the Pennsylvania Department of Conservation and Natural Resources does not think that way. They are more considered with getting people outdoors and meeting them where they are in their outdoor recreation journey. As opposed to bending them to their will.

That’s why I was so excited when they announced in 2025 that they were partnering with Timberline Glamping Company to bring glamping to seven Pennsylvania state parks in 2026. The public would have the chance to reserve one of the 54 fully outfitted sites —no gear needed.

Glamping will be available in Pymatuning, Hills Creek, Promised Land, Hickory Run, French Creek, Codorus and Laurel Hill State Parks.

Timberline will provide the beds, heat, air conditioning, coffee maker, linens, pillows and comfortable accommodations. All you have to bring is an open mind and a sense of adventure.

These wonderful glamping spots are creating space for everyone to experience the magic of nature in their own way. By making the outdoors accessible for everyone- from people who don’t own camping gear to those physically unable to sleep in a tent - glamping is opening doors, breaking down barriers and reimagining what it means to “get outside.”

Because nature belongs to all of us — whether you’re sleeping under the stars or under a heated canopy.

On this episode I speak with Nathan and Rebeka Self, founders of Timberline Glamping Company, and Kaitlyn Gundersen-Thorpe, manager of the French Creek State Park Complex.
