Well, another amazing day.

Well, another amazing day. One of the things you realize as you get older is that time is precious. As we get closer to winter, good outdoor days become even rarer. The plan we started last week and posted about got a lot of traction. When I arrived this morning, a...

Silage Pit to Sledding Hill in three easy steps

Phase 1 of transforming the old silage pit into a restored winter sledding hill for kids is now complete. As a prelude to the Saturday 9 am work party, John and I headed out for a quick check and cleanup. Two hours later we had cleared and prepared the entire pit area for the full work party. You can now clearly see the pit, the slopes, and its full size. I even used John as a comparison in the photos.

Exploring Oak Hill: A Hidden Gem in Chelmsford’s Natural and Industrial History

Nestled in the northern reaches of Chelmsford, Massachusetts, Oak Hill Conservation Area offers a unique blend of natural beauty and industrial heritage. Spanning approximately 66 acres, it invites visitors to explore wooded trails, remnants of granite quarries, and a rich history dating back to the early 19th century.
The story of Oak Hill begins in the early 1800s when the region’s granite was highly sought after for its quality and durability. In 1826, Isaac Carkin began extracting granite from Oak Hill, marking the beginning of a significant industry in the area. Over the decades, quarrying operations left behind remnants that can still be observed today.

Heart Pond: Born of Ice, Named for Love, Remembered for Ice Blocks

If you have ever strolled the beach at Heart Pond on a summer afternoon, it might feel timeless, but the pond’s story actually begins 12,000 years ago, when a retreating glacier left behind a giant block of stranded ice. As that block melted, the earth around it collapsed, forming what geologists call a kettle pond. Heart Pond is one of those rare relics, a deep, round basin, about 91 acres, with water as old as Chelmsford itself.

Reflections on Halloween Week Events

Well, two big events are now behind us, what we like to call our “Halloween events,” and we have a few days’ break before we start the “Thanksgiving events.” I wanted to take a moment to reflect on what happened and how it all came together.

Chelmsford doesn’t have a full recreation department like many surrounding towns do, so it’s the residents and community groups who organize most of the events you see. These events don’t have large budgets or resources behind them, but what they do have is a tremendous amount of heart.

Whether it’s a trunk-or-treat, a small neighborhood Halloween parade, or a party and movie night in one of the old town halls, Chelmsford residents have figured out how to make things happen with just a few dollars and a lot of creativity.

What is a silage pit?

With the weather too cold for painting, our weekend work will shift to clearing the old silage pit at Koulas Farm. The pit sits just to the left of “Big Red” and is about 40 feet long. It’s only a few feet deep with gently sloped sides, making it a perfect and safe...

Blanchard’s Meadow: Historic Condition and Changes Since Town Acquisition

Blanchard’s Meadow has been part of Chelmsford’s agricultural landscape since before 1671. For centuries, it functioned as a managed hay meadow with shallow ditches and channels designed to carry away excess surface water while keeping the soil moist and productive. These drainage systems were maintained by local farmers and community members and remained in use until the year the Town of Chelmsford acquired the property.

Maple Syrup

How Sweet it is (Jackie Gleason)

Ten years ago Town Meeting voted to try a different type of agriculture lease at Sunny Meadow Farm. The goal was long term thinking. Maple trees grown in a plantation style orchard take close to a decade before they can be tapped, so the town approved a ten year lease to make it possible. Like many experimental ideas, the timeline was interrupted by Covid delays and the process stretched out. Instead of tapping at year eight, the first real tapping will now happen this winter in year ten.

Work party planning

With a little Help of our Friends (of Koulas)

Well, it is the first work party at Koulas and I am excited to get back out there and make a difference. From all the prep work, the site is in good shape and this should be a great start. I would expect low exposure to ticks today which means good walking conditions if people stay on the main routes. Someone shared photos that deer have returned to the meadow which is a very good sign. There is also a very large coyote in the area and one was seen on Lantern Lane last night. So please make sure your dogs are always leashed on this site. This is required on all town land and especially important at Koulas.

Vandalism

ATV’s and Wetlands not a good mix.

What is going on at Wright is actually pretty simple. For as long as I have been in town, kids have been riding up and down the powerline trails on ATVs and dirt bikes. They always have and probably always will. Gates and No Trespassing signs do not make much difference. It has been part of the landscape there for years.

COSS supporting community groups

Whats’s old is new again

Today was another great E-Recycle Day, hosted by the Center School PTO and the McCarthy Middle School PTO. This is one of those events that really shows what community looks like in Chelmsford. The funds raised go right back into local PTO programs that support students and teachers, so every old TV, laptop, and toaster dropped off helps make a difference.

Rocking out at Koulas Farm

Yesterday’s work party at Koulas Farm gave me a chance to introduce some very old technology to new users. This wasn’t for a history lesson or nostalgia, it was because this technology just works, and it works well.

Say hello to “Throne Rock” at Koulas Farm

Say hello to “Throne Rock” at Koulas Farm. Every now and then when you are out doing restoration work or cleanup, something interesting pops up. Koulas Farm has a few of these surprises that over time have earned names of their own. There is “Stone Bridge,” “Split Rock,” “Silage Pit,” and “Big Red.” Mention any of these to the regulars and you will get an instant nod and probably a story about how it got its name.

It’s all Down Hill a Sledding Hill Evaluation at Koulas Farm

As a member of the Koulas Task Force, I know there has been interest in adding a sledding hill there because safe public options in town are limited. The town has always said it is open to new ideas from residents, so from time to time I come up with them. Sometimes it’s ideas like making Red Wing family friendly, building community gardens, adding pollinator gardens, or finding locations for a Storybook Trail. This is not something new. Sometimes these ideas happen, sometimes they don’t, and sometimes a variation happens. That is understood with any plan and is key to a good community decision.

Hidden History of Chelmsford

The Lime Quarry and the Lost Pond

The Lime Quarry Reservation off Littleton Road holds one of Chelmsford’s oldest industrial stories. Long before the highway or modern houses, this area was a working quarry where stone was burned into lime for building mortar and plaster. The first kilns and quarry pits appeared in the 1730s, and by the early 1800s as many as five separate lime operations were active. The work was tough and hot. Quarrymen split limestone from the ledges using hand drills and black powder, loaded the stone into ox carts, and hauled it to kilns built into the hillside. Inside each kiln, the stone was fired for days with stacked wood until it turned white and crumbly. The finished lime was packed into barrels and shipped to builders in Chelmsford and Lowell.

The Amazing Decorated Winter Tree Scavenger Hunt has become a tradition for many families and civic groups and is a fun way to enjoy our open spaces during the winter season. We welcome new decorators and returning decorators.
This program highlights community spirit, creativity, and outdoor enjoyment. Trees are not hidden. They are placed along main trails so families can easily see them and safely stop for a visit and photo.
