A couple of twinned rhombehedral groups of calcite with oxidized goethite in the highly altered orange andesite. The area's also good for siderite roses/stacks with frosty calcite rhombs. The one in front is 3 in. between points. Taken quickly as a mineral rescue operation was underway with the excavator coming 'tomorrow'. end of 2003

Attractive stalactites of druzy Quartz in a partial geode section. The repaired specimen is 7 cm tall and is a part of the John Lindell collection, ex from the Gil Griffin collection. Robert Meyer photograph.

A 2.5 cm steep rhombohedral crystal of Calcite jutting like a shark’s fin from stalactitic druzy Quartz. Measures 5 cm long. The tiny golden spots are micro sprays of Goethite (as depicted in other specimen photographs from Walker Valley), and are endemic of specimens from the locality. From the John Lindell collection, ex from the Gil Griffin ...

There are actually two pockets "vugs" in this specimen. The nicest one shown and the other is very nice twice as large although the pocket is seen well with a light I chose not to remove an outside plate to expose the vug. I may though one day choose to but not for now.

In 2012, Bart Cannon from Seattle has offered identified specimens of this amphibole to the Mindat-members for free, you just had to pay the mail. I am glad to have such a special specimen. Collection and photo Erik Vercammen

Flattened rhombohedra of Calcite with multiple overgrowths of drusy white and brown Calcite.The ding near the center allows a look at the layers.The Quartz is Amethystine.Oxidized Goethite might have contributed to the brown color. Specimen is 7cm wide.Self collected in 1991.

My photography skills cannot capture how really bright and sugary this specimen is. The best I have ever seen from the locality. Specimen is 6cm wide. Self collected in 1977.

The other half of the geode with Calcite, Siderite and Hematite I found hard rocking in the geode pit at Walker Valley.

My very first amethyst out of hard rock!

The sample is 5 cm x 4 cm. A druse of light purple coloured, 5 mm, Amethyst crystals with minor 1 mm Goethite hemispheres. Some of the Goethite could be removed by chemical means but most is overgrown by Quartz. The Amethyst druses at this locality have a clay-like rind between the Quartz and the surrounding rock so they can be freed as plates, ...

Massive stilpnomelane veined with quartz. Photographed by, and in the collection of Dan Costian.

7" x 5 1/2" x 7" deep Right in the middle of the self-supporting vug are a couple of natural holes in the rind. The entire vug could fit two basketball volumes and had two standing columns of the same, growing around six inch rods of quartz. The inside was partially filled/coated with black irony muck as the hisingerite rind had mostly ...

This specimen measures 1.25x0.75x0.75 in.

The crack in the lower right side occurred naturally. 14cm wide, self collected in 1977.

Such spherules of stilpnomelane on quartz matrix are typical for the locality. They consist of platy radial crystals. The gray-greenish color is due to glaucophane. Photographed by, and in the collection of Dan Costian.

Self Collected 2016 This is half of a great specimen, the other half is in a friends collection. Clear Quartz with calcite and hits of yellow (siderite) trapped within.

Popped this stalactitic goethite out of it's "geode" that exposed in the wall of andesite at the geode pit in Walker Valley, Skagit County, WA

This is not from the main pit but from a spot I found wondering around on some bike trails. After I cleaned this and soaked it, the purple became obvious. I hope I'm close to a big hollow purple beauty.

Black glassy hisingerite with pale-colored platy siderite, on andesite matrix. The hisingerite is translucent and shows a dark brown color under strong lighting. When I first saw hisingerite at Walker Valley, I thought it was obsidian on basalt. I brought a piece to a public identification event at the Burke Museum (Seattle, WA), and was told ...

A small pocket of goethite with siderite on bottom center (green). Found in the pit at Walker Vally, Skagit County, WA.

Radiating black crystals frozen in white Quartz. JSS specimen and photo.

Calcite with a smaller calcite growing at a 90 degree angle. Found in the pit at Walker Valley, Skagit county, WA

16.4 x 11.4 x 7.4 cm. Bubbly, botryoidal, bi-colored strontianite forms a sculptural, large, 3-dimensional specimen. The tan outer layer coats translucent, amber to opaque, ivory strontianite botryoids. The encircled matrix really adds color and character to this large specimen from an obscure Washington locale. Seldom available. Ex. Bart Cannon ...

Popped a 50lb piece of andesite out of the wall and this was on the bottom side. Calcite on goethite rosettes with some siderite. The pit at Walker Vally, Skagit county, WA.

Calcite on siderite in an andesite matrix. Found in some new digs in the geode pit at Walker Valley, Skagit County, Washington, USA.

6.7 x 3.9 x 3.1 cm. An impressive and very uncommon quartz crystal stalactite combination from this well-known Washington locale. Sharp, glassy quartz points cover three sides of this pristine 360-degree piece, with the other side being covered with lustrous, colorless calcite rhombs. The rhombs have modest pink fluorescence. Ex Kay Robertson ...

This specimen has a clastic nature w/large milky-white quartz clasts in its center surrounded quartz clasts that are included w/reddish-brown spherulitic stilpnomelane rosettes (≤3 mm in diameter). Dense reddish-brown→black stilpnomelane veins and masses occur throughout the remainder of the specimen. Collected by Bill Hamel in June, 2006.

Black glassy hisingerite with light brown platy siderite, surrounding a quartz nodule. The hisingerite is translucent and shows a dark brown color under strong lighting. I had similar material identified as hisingerite by an expert at the Burke Museum (Seattle, WA; visual identification by someone familiar with the deposit). This ID was ...

2.6 x 1.7 x 1.2 cm A really cool and attractive specimen of the lesser known calcites from Walker Valley, Washington featuring a 1.5 cm semi "rosette"-like group of calcite on matrix. The piece is in great shape and stands out as the best I think I have seen from this locality, even for the smaller size. Ex. Jim Robison carbonate collection.

A rarely seen pseudomorph of snow white strontianite replacing crystals of celestine measuring up to 1.2 cm from the Alverson Mine in La Conner, Washington. The underside of the piece shows a minor amount of the remaining blue colored preexisting celestine. A really cool and hard to find specimen from the prestigious pseudomorph collection of Dr. ...

Ugly stalactites of goethite partially fill this quartz geode. Collected with no tools, and one broken arm in the spring of 2002. I always imagined this could be a productive place with time and the proper tools.
