Garden Soil

Mother Earth

The Rund Woodlands are rich with many types of soils, minerals, stones and more.  Below is a work in progress, to identify and log the components that make up the terrain of the Woodlands.  



Dixonville silty clay loam

1.16 ACRES  14.24% 115 CU FT/AC

The Dixonville series consists of moderately deep, well drained soils formed in clayey colluvium and residuum derived from basalt. Dixonville soils are on hills. Slopes are 3 to 60 percent. The mean annual precipitation is about 45 inches and the mean annual temperature is about 52 degrees F.

TAXONOMIC CLASS: Fine, mixed, superactive, mesic Pachic Ultic Argixerolls, moderately cemented basalt.


DRAINAGE AND PERMEABILITY: Well drained; slow permeability.

USE AND VEGETATION: These soils are used for native pasture, hay, small grains, row crops, sweet cherries, filberts, and woodland. Oregon white oak and Douglas fir dominate the tree canopy. Other species are bigleaf maple and grand fir. The understory vegetation is western bracken fern, common snowberry, western hazelnut, Pacific poison-oak, and baldhip rose.

DISTRIBUTION AND EXTENT: Foot slopes of the Coast Range and Cascade Range in western Oregon; MLRA 2, 5. The series is moderately extensive.


Philomath cobbly silty clay

0.34 Acres, 4.20% 45 CU FT/AC 


The Philomath series consists of shallow, well drained soils that formed in colluvium weathered from basic igneous rock. Philomath soils are on low hills. Slopes are 3 to 70 percent. The mean annual precipitation is about 45 inches and the mean annual temperature is about 53 degrees F.


TAXONOMIC CLASS: Clayey, smectitic, mesic, shallow Vertic Haploxerolls

DRAINAGE AND PERMEABILITY: Well drained; slow permeability.

USE AND VEGETATION: About 80 percent of this soil is in natural and unimproved pasture. It is also used for water supply and for wildlife habitat. The native vegetation is grass, baldhip rose, and Pacific poison-oak with a few patches of Oregon white oak.

DISTRIBUTION AND EXTENT: Foothills of the Coast Range and the Cascade Mountains in Western Oregon; MLRA 2, 5. This series is of moderate extent.



Ritner cobbly silty clay loam

6.65 Acres, 81.56%, 129 CU FT/AC


The Ritner series consists of moderately deep, well drained soils formed in clayey colluvium derived from basalt dominantly from the Siletz River Volcanics Formation. Ritner soils occur on broad ridgetops and side slopes of foothills and mountains. Slopes are 2 to 90 percent. The mean annual precipitation is about 50 inches and the mean annual temperature is about 52 degrees F.

TAXONOMIC CLASS: Clayey-skeletal, mixed, superactive, mesic Humic Haploxerepts


DRAINAGE AND PERMEABILITY: Well drained; moderately slow permeability.


USE AND VEGETATION: These soils are used for timber production, hay and pasture, limited homesite development, wildlife, and watersheds. Native vegetation is Douglas fir, grand fir, ponderosa pine, bigleaf maple, Oregon white oak, western brackenfern, common snowberry, western hazel, Pacific poison oak, baldhip rose, trailing blackberry, evergreen blackberry, western swordfern, American trail plant, fragrant bedstraw, coolwort foamflower, Oregon iris, common whipplea, mountain brome, western fescue, and white hawkweed.


DISTRIBUTION AND EXTENT: Foothills and mountains bordering the margins of the Willamette Valley in Oregon; MLRA 2, 5. The series is of moderate extent.



Tertiary fossil
(petrified woods)

Tertiary fossil (petrified) woods are to be found throughout most of the Western Cascades adjoining the eastern side of Oregon's Willamette Valley, but those deposits making up the area known as the Sweet Home Petrified Forest in Linn County are among the most abundant and well known.

Clear Quartz

Quartz is one of the most common minerals found in the Earth's crust. If pure, quartz forms colorless, transparent and very hard crystals with a glass-like luster. A significant component of many igneous, metamorphic and sedimentary rocks, this natural form of silicon dioxide is found in an impressive range of varieties and colours.


Carnelian Agate

Carnelian is the red, orange, or amber variety of Chalcedony. Though often a solid color, it may also be banded, in which case it would be jointly classified as both Agate and Carnelian. Carnelian is an ancient gemstone, having been used as gem material since antiquity. Although still used a gemstone today, its significance and value has been diminished since the ancient times.




Agates have been used to create stunning jewelry, beads, vases, ornaments, and other artworks, and is considered a semiprecious gemstones.  The term "Agate" is also used for non-banded chalcedony with various types of inclusions such as moss, plum, or flame agate.  Distinctive bandings, color patterns, and "impurities" make the agate unique and desirable. Composed of silicon dioxide SiO2, agate is a translucent or semitransparent fine-grained microcrystalline or cryptocrystalline quartz.



Obsidian is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock.  Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolitic lava flows known as obsidian flows. These flows have a high content of silica, giving them a high viscosity. The high viscosity inhibits diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava.



Holley Blue Agate

This incredible blue to purple seam agate is one of the most popular agates in the western Oregon area. There are also a few known and probably more undiscovered deposits of Holley Blue on the Calapooia River. The Holley Mt. area is the main area for this famous lapidary material. It is located on leased timberland. Bulldozed over and replanted it was closed to digging as of spring 1997. The land is leased to Cascade Timber Consulting, who currently control access to the site. People who have dug since then have been cited for trespassing, had their rock confiscated and were fined.



Jasper is a fine grained quartz with a host of foreign matter. It is formed in the sedimentary manner when the original silicic acid solution penetrates clayey or sandy rock or is itself permeated with a multitude of suspended particles. When the silicic acid solidifies into quartz; the clayey, sandy, or finely distributed particles remain and enclose within the jasper as it forms and give it its opaque color and unique markings.  Jasper is a mineral that can occur almost anywhere and appears in a wide variety of forms. The different markings found on these varied representatives of jasper have led to them being traded under a plethora of imaginative names.

Oregon Fire Opal

Fire opal forms when water seeps into silica-rich lava, filling seams and hollows. Under heat and pressure, the silica forms a solid gel, trapping the remaining water within its structure. Seams of fire opal are found within the remains of these ancient flows. Oregon Fire Opals are a natural gemstone with no treatments of any type. They are translucent with warm colors, ranging from yellow, orange-yellow to red. Oregon Fire Opals can be carved, faceted into beautiful gemstones, or made into world class works of art.
