Rock Art on the Susquehanna
For hundreds, if not thousands of years, the activity of creating rock art flourished on the lower reaches of the Susquehanna River. Although the majority of these ancient carvings are now under water impounded by dams, those remaining still constitute the largest concentration of Native American petroglyphs in the northeast United States.
Paul Nevin has been researching, documenting, and visiting these rock art sites for more than forty years. In this program, Paul presents a survey of these enigmatic sites, with a special focus on the spectacular Safe Harbor Petroglyphs, located on the Susquehanna River in Lancaster County, Pennsylvania.
Paul Nevin is president of the Lower Susquehanna Archaeological Society and former Director of Susquehanna National Heritage Area’s Zimmerman Center for Heritage in Wrightsville, PA. Acknowledged as the leading authority on the rock art of the lower Susquehanna River, Paul is the author of the new book “A Guide to the Safe Harbor Petroglyphs.”
Natural History Society of Maryland’s Archaeology Club promotes the value of archaeology in Baltimore City, Baltimore County, and surrounding areas. The goal of the Archaeology Club is to educate citizenry in the ethics, methods, and artifact preservation methods of archaeology and how archaeology can be used to document, discover, and promote local history. The Archaeology Club is inclusive to all persons who have an interest in archaeology.

Annelids of Maryland featuring the Water Nymph Worms
มุมมอง 1147 ชั่วโมงที่ผ่านมา
Annelids, or segmented worms, are a highly diverse group of invertebrates that are key components of marine, freshwater, and terrestrial ecosystems. They include the familiar earthworms as well as a large diversity of less familiar freshwater and marine worms. Often one of the most abundant animal groups in an ecosystem, annelids perform key ecological roles including affecting sediment charact...
Maryland Shark Attack of 1640
มุมมอง 3114 ชั่วโมงที่ผ่านมา
Shark attacks on humans are rare, but they have taken up residence in our collective consciousness as a fear generator, bolstered by seminal Hollywood works such as the iconic Jaws franchise. This collective fear started building much earlier, maybe in 1916 when there was a series of deadly attacks in New Jersey, as chronicled in the book 12 Days of Terror by Richard Fernicola, a physician and ...

Wood Turtles are distinctive turtles that occur in Maryland, and unfortunately their population is declining. These striking-looking turtles inhabit freshwater streams and the adjacent floodplains and forests. John Garrison has spent countless hours studying the movements, habitat use, and nesting ecology of this species so we can better understand how to protect its populations. John is a wild...

Throughout the Cenozoic, many species, especially herbivorous mammals, developed gigantic sizes worldwide (called megafauna). In this program, we review the evolution of the megafauna of the Americas, characterizing their diverse groups, revisiting their migration events during the Great American Biotic Interchange during the Pliocene, and discussing their ecological roles and paleoenvironmenta...
Roly-polies on the move: Terrestrial isopod diversity in Maryland

Depending on where you are from, you may identify them as roly-polies, doodle bugs, pill/sow bugs, or woodlice. These terrestrial isopods in the suborder Oniscidea are decomposers that influence leaf litter disappearance, nutrient cycling, and other ecosystem functions. The distribution and diversity of the isopod fauna in North America is poorly studied. Dr. Szlavecz, a soil ecologist and rese...

Blackbanded Sunfish: Maryland's Rarest Fish
I once saw a worm I've always wondered about. Context: I'm in Eastern Washington State, where we have hot dry summers and bitter cold winters. In the 1990s I had built a simple 12 x 16 foot pond with biological filter in my backyard. One summer afternoon I noticed a tiny transparent worm right at the waters edge, just under the water, moving a bit like an inch worm. It was about 3/4 of an inch long but would stretch out and contract as it moved, in addition to the inch worm motion. At one point the worm encountered a small pond snail which caused the worm to recoil and the snail to withdraw into its shell. Just as the snail seemed to relax and come out of its shell the little worm snapped forward, grabbing hold of the snail which pulled back into its shell, but apparently not fast or far enough because the little worm hollowed it out. Anyway, this program is the first time I've ever heard of worms that eat snails being talked about. I don't think the worm had segments, I'm pretty sure it didn't have any appendages but it was so small and transparent I didn't even notice a head, but it must have had some way of latching on to the body of the snail.
Paul is the best! He has so much knowledge and it’s great to learn from him. Excavated with him this past summer.
Very informative video. Thank you for putting it together and sharing your knowledge. The world needs people like you to help preserve and promote such histories, so they’re not lost to time and forgotten about. Regarding the preservation of the petroglyphs, has anyone considered having them scanned by laser? I’ve seen documentaries where lasers were used to scan ancient rock art to make the glyphs more visible and allow more detail to be seen. I’m curious how many more details and information may be able to be gathered if laser scans were able to be completed. As for the Susquehanna Deeps, I know they were semi-explored before the dam was built. Has any exploration of the deeps been done in modern times? If I had the time and money, I would love to send an underwater drone to explore the depths. I imagine doing something like that would be both exhilarating and nerve-wracking at the same time. I would be in constant fear of the drone getting caught up in hidden logs, branches, and other debris that certainly inhabit the depths of the deeps. I’m also very interested in learning about and preserving the history of the Susquehanna River. I’ve actually been working on paddling and documenting the entire 444 miles of the north and main branches of the river for a few years now, though it has admittedly been a very slow go. Logistics and time seem to be the primary limiting factors. As such, and as many do nowadays, I have a TH-cam channel. My goal is to share the sights and sounds of the river as well as preserve its history for future generations. That being said, would you permit me to use clips from this video in my future videos? After having my channel up and running for a few years now I’ve amassed a whopping 221 subscribers. Fortunately, my goal is the transmission and preservation of knowledge and not to make money from it. If it was to make money, boy oh boy would I be in trouble! Before commenting here, I went and checked out the Natural History Society of Maryland page. It appears that there are lots and lots of opportunities to explore and learn! I will definitely be joining as a member and signing up for events, especially the canoe paddles! I was already anxious for warmer weather so I could get back out on the water, but after discovering the NHSM club and the opportunities being offered to get outside and learn, I am all that more anxious now. As for the many books referenced in the video, can you provide a list of them? I’d be interested in taking a closer look at them and possibly purchasing some if they’re still in publication. Speaking of purchasing them, are there any links available for those who may be interested in buying them? Thanks again for the very informative video. Keep up the great work! I look forward to seeing more from your channel!

I'm from Springhill, Nova Scotia. We had much the same geology as we see here. They also have a Miner's Museum offering tours of an 1873 mine. You can even dig for coal; just watch out for the coal chips; the seam is still under compression.
Oh my goodness you help me so much on my science project because for over an hour I was trying to understand it but there was too much information. This helped me greatly THANK YOU!

This all makes such common sense to me. Ive always wondered why no one had done this as all the coasts would have been under water. Hmmm.
