Many us are increasingly turning to the outdoors and nature for exercise, comfort, and a breath of fresh air on the Old Croton Aqueduct Trail. Please remember the words from the Appalachian Trail. “Pack in and pack out” and please take your trash with you. It is important to all of us to keep one of our most precious resources safe and clean during this time. Enjoy the Trail!

Just emerged Black Swallowtail Butterfly

This is a Black Swallowtail butterfly I raised last season, drying its wings as it emerges from its chrysalis. I am posting this in celebration of Earth Day Lower Hudson PRISM I celebrate the earth in all of its aspects, for we are one with all of its wonderful creatures; I cherish the opportunity to be out in nature and to encounter what I consider to be my friends and family. I also want to give tribute to all of the mentors who have taught me over the years how to truly see what I am observing. Thoreau said: It’s not what you look at, it’s how you look and whether you see. Doug Tallamy said “In the end we will conserve only what we love; we will love only what we understand; we only understand what we are taught.” My mentor Gary Lincoff taught me how to see the features of fungi; now I will not go into the woods without a loupe to see the small details. Taro Ietaka taught me how to look at lichens and mosses and now I can identify a few of them; he also recommended what has become my favorite book, Gathering Moss by Robin Wall Kimmerer. Carol Levine taught me how to observe twigs to identify trees, who knew? Terminal buds, bud scale scars, phyllotaxy, the manner in which the leaves are arranged on branches and so much more including How to Identify Wildflowers in Winter. Carol Gracie taught me how to look at the details of flower structure in person and with her special field guide and other books. Bill Yule taught me to understand how the fungi nourish the trees and plants and help them communicate with each other. Jim Miller taught me how to look at caterpillars and moths. Linda Rohleder taught me how to identify many invasive plants. And so many more. Studying and sharpening my observational skills enhances and gives meaning to my life. This is what then motivates me to be a nature activist, planting native plants, removing invasive ones and teaching and motivating others. Diane Alden

Chat Conversation Start 1.7K people like this Park 11:21 AM What can we do about the littering on the OCA trails? Now that more people are home and with many discovering the trails I have seen more trash on the trails then usual. The ventilator #19 is located behind my backyard and people leave trash near and on it daily. The Untermeyer park is about a 5min walk from me and they have a trash can behind the welcome sign easy to reach from the gate even if the doors are locked. Last year one home south of mine off the trail fence caught on fire due to a cigarette.😔😥
With 60+ degree weather in NYC this weekend, my brother, his girls and I made a wonderful decision to visit the Old Croton Aqueduct Historic State Park in Dobbs Ferry, NY on Saturday. It's a main access point to an easy 26-mile scenic walking/hiking/biking trail atop the Old Croton Aqueduct. We parked and started at the 1857-built Keeper's House which is free, open to the public, where Mavis Cain, President of Friends of the Old Croton Aqueduct taught us much about the history of the Old Croton Aqueduct, which went off-line and stopped supplying water to NYC in 1955. Constructed from 1837 to 1842 to supply Manhattan with fresh water, the Old Croton Aqueduct lies buried in a man-made sloping dirt berm. So, the trail runs right on top of the berm and therefore, the old aqueduct. The scenic trail runs atop the northernmost 26-miles, although the aqueduct itself is 41 miles long, and carried water by gravity from the source (Croton River) to Manhattan. The height of the gravity-fed aqueduct drops 1/4" per 100' (13 inches per mile), taking 22 hours for gravity to move the water down the 41 miles at a speed of 1.86 miles per hour to reach Manhattan. It was built because local water sources for Manhattan had become polluted and inadequate for the growing population – which was just 319,000 people living in Manhattan at the time (1842). There was no plumbing for fresh water, no wastewater or sewer systems. Wealthy people had water delivered to them by the Manhattan Company, a water company which eventually became Chase Manhattan bank. Much of the above info is from Wikipedia. We walked the trail about 3 miles. Many empty bird nests and squirrels in the trees along the way. A good day was had by all. We hope to return again once spring has sprung!
We loved the nature, history & unique facts about Ossining & stories about the aqueduct past & present that was exceptionally led by Friends of the Old Croton Aqueduct Star ⭐️ tour guide Leslie! It was called Weirs to Beers 🍻 & ended with Sing Sing Kills brewery stop in Ossining! We will definitely go again. I couldn’t believe how three hours in Ossining could be so great & free activity!
Does anyone have a gpx file or map of the section of the rtoue in NYC? Trying to plan a run of the whole 41 miles.
Never know what you’ll see on the trail!
Does Your Library Have a Library Telescope program? A Library Telescope is a telescope owned by a library that can be borrowed just like a book. Usually it’s a modified Orion 4.5” StarBlast Reflector Telescope. Shouldn’t your library have one? What better way to bring astronomy to the youth of today, than to give them access to a telescope? Having a parent, or other adult, borrow the telescope and amaze a child with views of the Moon or a planet, could make a lasting impression. Maybe even lead to a career in astronomy or some other science. Hundreds of libraries across the US have Library Telescope programs that have been remarkably successful. A library can get a telescope program going for under $400. Does your library have a Library Telescope? NO? You should get that fixed. See page: Library Telescopes for more information.
A tale about the trail.
I enjoy walking the adeqeut
It's official! We completed the OCA in 2 days! From Croton Gorge Park to NYC Public Library. Amazing experience!!! We meet some many extraordinary people alone the trail who made our journey magical! A special Thank you to Carlos Gee for sharing his journey notes of the Westchester section. To my brave companion Manami, congratulations and thank you for let me witness your love and passion for nature and history.
I have a book titled "Second Annual Report of the Department of Public Works of the City of New York, for the Year ending April 10, 1872." It contains 7 tipped-in photographs by Rockwood of NY. Titles of photographs are: Croton Dam and Aqueduct Gate-house; Water-mains laid on Tenth Avenue; Repairs to Seventy-two-inch Water-mains; Reservoir Dam at Boyd's Corners, Putnam County; High Bridge and High-service Engine-house and Tower; Regulating and Grading Eighth Avenue; & Rock-cutting for Sewer, Eightieth Street and Eleventh Avenue. There are also several other illustrations that are not photographic.
