It's hard to reckon the precise tonnage of rock that I have gathered from the inner bluegrass region these past four years. I have no scales, so instead I tend to measure such things in minor back aches and fall fires around rock fire-pits.
But irrespective of the precise number, here's what that tonnage has built in Lexington: four small guerrilla gardens atop drainage ditches and astride fences in places like the Rupp Arena parking lot (all of which are waiting to be re-inhabited); two separate rock walkways (approximately 40 feet in length and partially adorned in creeping thyme); a rock fire-pit surrounded by rock patio that was built into a double terraced rock flower bed (all this more or less a 120 square foot thing that reaches a height of 3 feet); a 40 foot section of a partially-raised-bed garden that backed up to a fence/property line; a terraced 200 square foot garden built atop what was previously an unusable steep incline of weeds behind my former house; a 30 foot long rock fence (as yet only partially completed) at my current home; and sundry other projects taken on alone and with friends.
The list could go on were I to include into my figures things built in Jessamine County, but I think you get the point. I like to collect and stack rock and do it quite frequently.
My attraction to rock is both practical and aesthetic. Moving here in 2000 for school, I have been continually struck by the power—aesthetic, historic, racial, economic—of the inner bluegrass region's rock fences. When we first moved here, my wife and I would take long rides in the country, both by ourselves and as part of those weekend tours we gave visiting family and friends.
As I have lived here longer, my fence experiences have become more tactile. I have scraped my boots and jeans hopping an eighteenth century rock fence that divided land near the Kentucky River that Daniel Boone helped survey, and more recently I have periodically helped re-stack an only slightly newer fence in Keene, KY. I have now walked enough Kentucky ground to know that my interest in rock fences lies mainly in the rock: Limestone mostly, and shitloads of it, all over the region, used in the construction of beautiful fences, terraces, mills, bridge bases, houses, garden and flower beds, retaining walls, and culverts, to name a few rock creations old and new I've come across and marveled at.
This last learned attraction,the historic multi-functionality of rock, is also practical. I first experienced the practical use of stones when trying to figure out what to do about the dirt and mud path created by our two dogs that stretched across the back yard of our former home. Grass seed did not work, discipline and (later) pleading did not work, and the pea gravel I paid to get dumped there to make a walkway was messy and stuck in my barefeet when I walked in it.
When friends in Carlisle offered us the rocks strewn across their property that had been ripped up in the making of their new home, I began gathering rocks for a walkway. By the time I finished the firepit and terraced garden, I realized that in addition to its utility as walking surface, rocks can raise garden beds, separate areas of my yard, level uneven land, provide a building beam to perch my canoe upon, and otherwise create an aesthetic “hardscape.” I also learned that I didn't need to go to Carlisle to get it. As I began to look and see how much was available, gratis, at ripped up construction sites, interstate cutouts, water-main projects, and excavation sites in our own yards, I saw the economic and aesthetic practicality of choosing homegrown rock over Lowes-bought faux-rock.
As with most things, collecting and stacking rock is both infinitely easy and gloriously nuanced—an activity for both green beginners pulling a one-off project and craft tradespeople getting paid for their enhanced skills. Here's the easy version, which is restrictive to the degree that it assumes automobile access and physical ability to lift things weighing between five (5) and one thousand (1000) pounds: Get in your vehicle and locate rocks accessible to said vehicle. Load rocks. Drive home, unload product by stacking it. Repeat as necessary.
It gets more nuanced, of course. First,trucks are better vehicles to use than Cooper Minis, though I find it instructive to note that community gardener Michael Marchman, “Notable Neighbor” for the August issue of Chevy Chaser, used the trunk of his stepfather's Buick Park Avenue to transport the rock grabbed for his public sidewalk garden located on the corner of Hart and Ridgeway. Commuting to Northern Kentucky University where he has found adjunct work as a teacher of geography, Michael grabbed rock off cutouts on the sixty mile stretch of I-75 he drove twice a week. It took about fifteen minutes per excursion as he selected and then moved the chosen rocks to his trunk. All in all, this took Marchman less than a semester of 15-minute respites from his car to build a garden now in its second year of harvest.
On the collection side of things, there are other nuances I've learned. Nearby rock outcroppings are easier in both the arrival and the departure. I'd suggest to stay within twenty-five miles, mostly because it's ridiculously easy to do. Sunday mornings are good times to hunt rock since most of Lexington and its police force are engaged in various religious activities. Home construction sites often result in mounds of rock upturned from the earth; rock mounds are preferable in that you can roll heavier rocks down them and into your truck bed rather than heaving them into it.
If you are collecting rock from ground torn up for active construction, stay out of the way of workers and visit when you will not be in their way. If you collect from other sites, make sure that your taking does not negatively impact the physical and cultural environment in which it sits. Thank friends and acquaintances who offer their rocks. And finally, go travel the road to Galilee: the ripped up stretch of Harrodsburg Road beginning past the great Christian megachurches and ending at the turnoff to Wilmore and Asbury Seminary. I don't know if it's legal or not, but my hunch is that rock gleaning is supported by at least some part of Christian thought.
On the stacking of stones, I'm more a practitioner than a craftsperson. But I have found that wider bases seem to make more sturdy structures. So does stacking to avoid long running vertical joints. This happens when you put two ends together on one level (making a joint) and then put two ends together at the same place for the next set of rocks stacked on top. Vary the joints, and make level stacks of rock. Having level stacks gives you a much easier base to work your next layer of rocks. Use small rocks as backfill for support or as shems. Rocks want three stable points of contact to help be steady and the backfill helps keep it in place.
These are some basics of collecting and stacking, and they are from someone who has not spent much time learning the finer points of the craft. I collect and lay rock for a variety of reasons, so my things are not perfect. I am not an expert. I update, I fiddle, I repair, I move, I tend, I learn. I get a little bit better and then the simple process gets a few new fun wrinkles thrown into it.
But at its most democratic and simple, all you need to do to collect and stack rock is this: Look and think. Drive. Act. Go home. Tailor as you can and need.
