Old maps call this spot Gun Club Ponds, and it doesn’t take long, after walking the narrow strip between the railroad embankment and wall of Phragmites, that the gun club comes into focus.
A good place to look for waterfowl.
there’s slag here too!
a tunnel of european buckthorn leads us to the ponds.
it’s big leaf season as we head back over the tracks to the Indian Ridge Marsh parking lot.
I’ve been eyeing this site for a few years, never confident to visit it the first time alone. Who knew what was behind the overgrown tree-line at the edge of the lot?
We went together and it turns out that in late winter, perennial plants are greening up and glowing among the dreary cottonwood leaves. It’s a well-used place with past attempts at structures and social gatherings strewn about. No one else was here today though.
There’s a giant slag heap, one of the few in the area (but also: Shroud site, some parts of the old USX site). Holmes and Kubbing (2022) find slag heaps with ecosystems in Pittsburgh; in the Calumet Crescent we mostly see slag-filled depressions with slag as ground-level substrate. Remember that the Calumet was a vast wetland complex, yielding pockets in the landscape that were convenient to fill with steel production byproducts (e.g. slag) and other industrial waste.
The slag pile, or slag cliffs, rose up out of the woods of neighborhood volunteer junk trees: Ailanthus, ash, elm, cottonwood, a few juniper. The heap had clearly been used as a raised railroad spur, a way to transport in and out whatever was made here. To the east, these woods spread out and made way for big openings that have been used for ATV trails and bike jumps.
From the top of the slag cliffs, turning to the west was a delightful area with real promise: an ecosystem that grew up on slag and has created its own islands of organic material. A light canopy of slag-stunted rugged trees poked through diverse grasses. It looked like a slag savanna that may potentially be comparable to the high quality slag complex we see at Big Marsh and Marian Byrnes Parks?
It’s winter now, but this seems like a mesic area that might be wet enough for orchids?! I’d expect Liatris, hopefully Spiranthes, some sedges and rushes. We’ll revisit at the end of summer.
July is just the beginning of mallow season at Sand Ridge. Imagine the flowers twice as dense along the sides of the boardwalk – only a week or two away!
I didn’t remember that we had visited here in May before, but check out May 2017 to see what we found here a few years ago!
A gorgeously warm November afternoon yielded a golden IRM, with the last of the asters and goldenrod setting seed.
I started on the trail going north, through the wet prairie-
-and then kept going.
At the old Wisconsin Steel/Acme Coke site I found a new slag for the typology- charcoal briquet slag?! It was all quite dark black (some were also really lightweight), even if the raking sun bleached out some of the photos below. Or maybe this is just some coking byproduct.
It was really quiet and isolated in a sea of Aristida and a few interspersed cottonwoods and willows. I’m quite surprised I didn’t see any deer or other animals about. In fact, I was only surrounded by birds birds birds (mostly dark eyed juncos), in the the many standing dead trees – and a big crabapple – once back at Indian Ridge Marsh.
We hadn’t been to the south part of Beaubien in years. We thought we might get a chance to see lots of roosting birds in the trees, but I think we were too early in the evening.
We wanted to get close to the Little Cal so we went down by the railroad tracks, and like most days we CRAC, we thank ourselves for wearing muck boots.
I couldn’t get a good picture of the juvenile bald eagle we saw, but I promise it was there! The trees around this wetland are just the spot to rest and recuperate before going for a hunt over the Little Calumet River.
I’ve spent many months at Marian Byrnes Park- mostly doing research and botanizing. It’s where my favorite slag wetland is, a secret garden hidden behind a lovely woodland stroll. Just a few years ago, this park was pretty overgrown and inaccessible. Now it’s such a gem, with great shaded walking trails in a narrow savanna-esque strip, right off of 103rd.
Out on the slag, we see a human-modified ecosystem, just like the woodland (which of course is a highly managed park) but it’s such an unfamiliar landscape. You see remnants of its recent past as a flydumping mecca and plants that looks like weeds on concrete.
But with little human intervention for several decades in the management of this ecosystem, one could argue it’s more “natural” than the familiar tall trees and open understory along the path.
I had to start with the coolest thing we saw on our foray: woodcock eggs! We flushed their parents out of the brush from like 100 yards away. Questionable parenting.
St. Michael’s Church.
Some tiny buddies.
Moss is a critical early successional component of the ecosystem, accumulating organic matter than other species can eventually grow in.

Gothic Calumet.
Would you believe there are orchids and rare sedges on this slag wetland at Big Marsh?
I present to you the strappy leaves of Spiranthes cernua. 
…
This might be one of my most favorite photos at Big Marsh. I spent 10s of hours at this site during the summer of 2018 and literally never saw a bird in this tree! The site always seemed quiet in animal life, but rich in plant life.
