Landscape Rocks & Boulder Month – Rounded River and Glacial Rock

I typically have worked with 3 major categories of rocks and boulders in the landscapes I have designed and installed. Since I am newly-arrived in Kentucky, the more “Eastern U.S.” types of boulders and rocks – the Shales and the Limestones – have not been much in my headlamps. I truly admire their potential as the prior post points out. Particularly the limestone slabs interest me, with their horizontal possibilities. The list of more Western boulder types is this:

1. Rounded River Rocks, smoothed by tumbling under glaciation and running water

2. Fractured basalt rocks, into which I include “Glacial Schist” – also included in the Basalt rock  column would be the pillars and crystalline rocks of basalt origin

3. Igneous rocks of particular individual merit……….and I guess I could include Fossilized Rock – ‘petrified wood’ – as well, since I have actually used it in landscapes.

River/Glacial Boulders

I find these multi-utility rocks. They come in large numbers, very naturally. Aside from how we view the West, it was real wet at one time, with glaciers advancing and retreating, big boulders and small ones tumbling under mile-thick coverings of ice. As well, many rocks sat under water and the incessant pounding of running water rounded them off into interesting and sometimes literally circular shapes.

In landscaping, I like using these for water features (insert “duh!”), owing to the natural affinity with water in all its guises. I use them also for constructing artificial creek beds which double for a site as drainage trenches, moving rainfall and snow melt off the property and directing it where we want it to go. These are a delight to construct:

We assume the most natural effects in making these. Notably, for example, water will encounter an obstacle – such as a large rock – and find a way around it, thus the curving parts of my artificial creeks have larger boulders at junctures where the bends take place. We also try and find what would be a natural course, including its origins. When things make sense, the senses agree.

69

As can be seen above, I also use these to solidify a hillside as well. Inserting boulders does indeed help with erosion control, sitting all hefty and attractive, they supply ideal locations for planting as well as for diverting tides of water.

The picture below has a bunch of grouped boulders “Keyed” to prevent an erosive collapse onto what will eventually become an expensive and very long concrete driveway. They retain a secure place, especially when we add channels to it which will direct the water away. Nevertheless, this being such entirely new, basically ‘sculpted’ and not very compacted terrain,  and composed of soft, dusty, silty material, we did what we could to avoid future problems. It turned out, the first year, we were glad we did.

And we play, too, attempting to make remarkable pieces of art out of our soil and rock sculptures. For example, on this same property, we made sets of stairs out of large, up to one ton boulders, in two different locations. These stairs are not for everyday traffic but they were still functional, keeping one’s shoes out of the dirt and garden – the intent of any garden pathway.

The steps are on the right in this picture. If you enlarge it, you can far more detail and I am really not all that at editing pictures to show the features I want most to focus on. I just take them.

The above picture is taken at the bottom level, just as Spring had arrived and in time for us to address the disasters which a 100 year rain event had caused. We were more than a little glad we had taken what steps we did take to minimize erosion damage. It could have been worse. This project was about 6 months old at this time – in construction terms, from when we began.

This is another level up, between the home itself and a huge garage where garden tools and an RV shed are located. The stairs here are obviously on the right.

Other functional and very playful uses of these rocks carry a softening effect to hard surfaces –

But my single most primary usages of these gorgeously-shaped stones is generally related to their natural affinity with water.

Some Nearly Final Words On Boulders

Not all boulders are alike.

The Asian Section

Some even have titles of their own – “Shibumi Rocks” dot Japanese landscapes like these impressive doyens of timelessness who corner the market on Time itself. Many times, these gorgeous billions-of-years-old guys actually are the landscaping. These are the understated attention-getters who supply some peaceful perspective on those who pass and which abide in their Eternal reliability. Unless they fall over, of course. 😉

Other ‘rocks’ also fill this bill but in a far more bio-morphic – almost human way. Maybe even more to the point – in somewhat monstrous and unusual ways. The Chinese have perfected the art of placing boulders which are amazingly evocative. These things gather impressions for the more active parts of our imaginations as we get riveted by their near supernatural shapes. They probably most resemble those wild forms in the clouds we so often imagine resemble something we relate to. One can see shapes and guises for all sorts of imagined creatures and things in these amazing stones. That they fit so well into landscapes makes it even weirder somehow. The picture below is a “softened effect” as we see where the balance of plant and rock makes a fine compromise.

Somewhere else inside the Portland Chinese Garden, we get a different take or two. These suckers are plain bizarre:

HPIM1217

These incredible stones and their distinctly unusual messages come naturally for them. There are formations which feature these sorts of stones and which occur in Nature there. The Chinese who send for these are the exporters for very specific and limited environments like these gardens which they themselves construct.

I could look at these all day:

But that is China and Japan. In both cases, they are able to work with what they have in their natural geologic environment. I recall, having worked on this garden, the stockpiles of these stones as they arrived and as they were put into storage. I was eager to see how they expected to use them in the garden. I now think their placement was perfect.

The North American Section

Over here, we deal with a range of rocks and boulders which are really every bit as diverse, if not quite as weird in the same ways. We do have remarkable Shales and Limestones in the Eastern US which give us innumerable creative outlets. The stratified nature of limestone lends it to stacking and to flat planes. These are particularly impressive when used for water features, as these pictures from the corporate headquarters of Papa John’s Pizza illustrates – one of our favorite local Louisville walks.

Stacked, they make wonderful rockeries and informal walls for the surrounding foliage to fill out magnificently:

Here is a fabulous example of tasteful placement:

Moving towards Jeruselum………………….we encounter another perspective………as the sounds of thousands of gallons of water plummet over rocks and fall……

I’ll have to dedicate an entire post to this place soon.

More On Rocks and Boulders – Part 2

How can one take a postage stamp-sized back yard and landscape effectively? The image below is of a home with a 15 foot by 60 foot rear yard. Grass was out of the picture, owing to allergies and a sense of water-conservation on the part of the owner. Glaring sun was another factor – relentless and hotter than heck with still air a factor from the high fencing.

Use rocks!

A mix of perennials, some grasses, a shrub or two and a Decomposed Granite walkway gives us something which is at least interesting. This picture is about 2 months following installation and I can definitley say that everything grew remarkably well.

This property below was featured  in the post I made most recently. I just recently re-discovered these pictures I had misplaced. Here is how the Lunar Landscape evolved. Note the different types of rock. I used a river rock type in the creek bed, drainage swale and the more pretty igneous types in the rockery/bed. From these humble origins –

Below is the bare bones of a water feature project – among other facets of a complex operation – near a porch where we utilized Reno’s “rock assets” liberally. We “mined” a few of these and ordered up the more rounded river rocks. It can seem weird, featuring such a sun-burnt, crispy lichen-covered boulder such as this in the middle of a water feature, of all things, but the surprise element, mixed with its stunning color and texture was too much to pass up.

39

Honestly, using the river rocks is probably one of my favorite pastimes, in their billions of applications. As my companies have matured and individual “specialists” formed, it always seemed I would have one guy who took as much interest in making artificial creek beds as myself. Many projects would find me and “that guy” busy building little naturalistic creeks while the other slugs were off planting plants or making paver systems work. 😉

It’s a weakness.  Hey!   Look!  Here’s a specialist now!

41

Mixing can be as fun – after all a certain shamelessness never hurt in design and installing one’s own particular set of rules and non-regulations.

42

There are times when mixing a blend of volcanic rocks with the smoothed-out Granite, river-washed look can be effective:

The Use Of Boulders And More on Rocks and Stones

We revisit a favorite topic of mine and one into which I have invested hefty energies, through the years.

(left click all images to enlarge)

Stones. Rocks. Boulders. And even their smaller children, if such a thing can be said.

Particular individual rocks such as the one below from Reno, Nevada are among my very favorites. Igneous by origin, attached with fascinating lichens coloring things up dramatically, these solo rocks are completely entertaining by themselves. There is a nearly embarrassing richness of these in the surrounding hills and valleys of Reno and I would often encounter them just beyond a property line then shamelessly scoop them up for my own selfish decorative uses, I admit. Typically, I would be taking boulders whose lives as natural beauties was on a limited time span anyway – as the neighborhoods developed farther out.  I pretty much stick to a rule of sticking within eventual expansion boundaries, for the record. Anyway – Handling them always presented a big challenge inasmuch as pretty much the last thing one wanted to do was erase the lichens. So rolling them was definitely out. Once again, we thank the Machine Lord for providing clamps and buckets for extracting these rocks in relative pristine fashion. We would even use chains and padding and lift them gingerly with our machine buckets

25

It was difficult to stay way from a tendency to want to make a totally Lunar Landscape out of this one. The boulders used here were all “on site”, parched and par-broiled in the sun up on the ever-sunny slopes of the foothills in the Caughlin Ranch estates in Reno, Nevada.

26

The above  was taken at a rather raw phase, soon after installation. It does indeed look quite “Lunar” – which is exactly what the lady of the house said as she watched it develop. Yet, it morphed into something alotgether different as time moved along, allowing a future where pruning and ignoring plants and surrounding effects could determine what look one wanted to cultivate – Lunar or lush?

27

There are some stunning igneous rocks in this lot. Enlarging this view, below, hopefully some of the color will come out as we check the boulders in the foreground. Honestly, many of these stones told stories all by themselves. It often felt like dealing with literal personalities.

28

Then we come to the “rolling thunder” edition of “Rockeria” madness and the role and placement of larger, glacial or river-produced stones – rounder and ‘softer-effects’ sorts of rocks. For these, which can also be featured in the right spots, there is beauty in simplicity and plain size.

29

I’m going to divide this stream of posts up a bit more than usual. I’ll also enter them a bit more often.
