January Challenge #3

Original limestone curb still existing today

“Back in the Day”  the town was very prosperous and this particular street was in the ‘higher eschelon’ part of town — they got cut stone curbs

At that time the street would have been paved with bricks but has subsequently been covered in asphalt

It looks as though the snow plow has scraped along it relatively recently

Landscape rock — in this case pebbles of glacial origin

Glaciers brought an assortment of sizes of rock fragments and sorting by melt waters have produced many deposits of sand and gravel throughout Illinois

In landscape rock such as this or at a gravel pit a rock collection can be assembled in a very short time  — a very wide range of Igneous, Sedimentary, and Metamorphic rocks

Rocks edging a flower bed

More rocks and 3 modern day pavers

The large gray rock along the foundation shows flattened surfaces and scratches made by it transport in the glacial ice

The boulder just ahead of it with the red and purple clasts is an unusual quartzite known to outcrop in the Upper Peninsula of Michigan

Rocks such as this give an idea of how far and from what direction the glaciers travelled

(The brilliant white object near the downspout is a hunk of glass)

What you always wanted to know about grain sizes but were afraid to ask  😉

Very much enjoy all the entries you all have provided -- great to see the everyday cycling venues. Being in eastern Illinois, scenery certainly isn't our forte, but oh well, the roads are normally quiet. Look forward to more and more entries from all of you, I do have a few over on BL -- in Bill's Day Rides, and one journal.

    Another educational and interesting post from Rich ;’-). Growing up in what was then a very rural setting of Baltimore County, we had gravel and other small rock/stones, but also something I remember being called “cinders”. That was what covered many fronts of peoples yard entry from the road.
    I appreciate you list — thanks.

    Very nice collection of downspout rocks – I love the glacial scratching. As a kid, I loved looking through all the landscaping gravel in front of our house looking for fossils. My mom says I was a nerdy rock kid from a very young age. (I also remember that the house faced north, and on the really hot and humid summer days, the gravel in the shade on the front of the house was the coolest place to hang out – so maybe that’s how I got started!).
