Hey, so he's a little rambunctious. The fact that he his very first post is here in our game is...... Well just odd, but good! Welcome to the forum and the game Tweak!

To make it easier, it doesn't have to be a lava flow, any volcanic formation will do.

Those of us near Wyoming...Yellowstone and Devils Tower are both volcanic formations.

Theories of formation

Geologists agree that Devils Tower was formed by the intrusion of igneous material, but they cannot agree on how, exactly, that process took place. Geologists Carpenter and Russell studied Devils Tower in the late 19th century and came to the conclusion that the Tower was formed by an igneous intrusion. Later geologists searched for further explanations. Several geologists believe the molten rock comprising the Tower might not have surfaced; other researchers are convinced the tower is all that remains of what once was a large explosive volcano.
In 1907, scientists Darton and O'Hara decided that Devils Tower must be an eroded remnant of a laccolith. A laccolith is a large mass of igneous rock which is intruded through sedimentary rock beds without reaching the surface, but makes a rounded bulge in the sedimentary layers above. This theory was quite popular in the early 20th century since numerous studies had earlier been done on laccoliths in the Southwest.
Other theories have suggested that Devils Tower is a volcanic plug or that it is the neck of an extinct volcano. Presumably, if Devils Tower was a volcanic plug, any volcanics created by it – volcanic ash, lava flows, volcanic debris – would have been eroded away long ago. Some pyroclastic material of the same age as Devils Tower has been identified elsewhere in Wyoming.
The igneous material that forms the Tower is a phonolite porphyry intruded about 40.5 million years ago,[10] a light to dark-gray or greenish-gray igneous rock with conspicuous crystals of white feldspar.[11] As the magma cooled, hexagonal (and sometimes 4-, 5-, and 7-sided) columns formed. As the rock continued to cool, the vertical columns shrank horizontally in volume and cracks began to occur at 120 degree angles, generally forming compact 6-sided columns. The nearby Missouri Buttes, 3.5 miles (5.6 km) to the northwest of Devils Tower, are also composed of columnar phonolite of the same age. Superficially similar, but with typically 2 feet (0.61 m) diameter columns, Devils Postpile National Monument and Giant's Causeway are columnar basalt.
Devils Tower did not visibly protrude out of the landscape until the overlying sedimentary rocks eroded away. As the elements wore down the softer sandstones and shales, the more resistant igneous rock making up the tower survived the erosional forces. As a result, the gray columns of Devils Tower began to appear as an isolated mass above the landscape.
As rain and snow continue to erode the sedimentary rocks surrounding the Tower's base, more of Devils Tower will be exposed. Nonetheless, the exposed portions of the Tower still experience certain amounts of erosion. Cracks along the columns are subject to water and ice erosion. Erosion due to the expansion of ice along cracks and fractures within rock formations is common in colder climates – a prime example being the featured formations at Bryce Canyon National Park. Portions, or even entire columns, of rock at Devils Tower are continually breaking off and falling. Piles of broken columns, boulders, small rocks, and stones – or scree – lie at the base of the tower, indicating that it was once wider than it is today.[9]

As is most any other terrain in the Western USA, Canada, Mexico, a lot of Europe, South America, Africa, half the islands on the planet. This tag is easier than the cow that took two days for anyone to get. There are cows everywhere. You guys need to get out and ride more.

I got your cow...




Lava flows

Looks like part of your bike in the picture...the spirit of the game calls for the whole bike to be in the picture.

Nice lava flow. The Oregon boys can find that right down the road from Bend. We have them in our area as well. Even the Appalachian States have a few. Unfortunately, I don't think anybody in Florida is going to have a chance with that one.

Welcome to the game, and welcome to the GSR!

Nah...that's not true.
I've got several tags with only part of my bike in the picture...
We just want to make sure you didn't take your car, or bicycle, or airplane to get the picture....

Oh, I'm not giving the gears.

I think the tag is golden. I just really want to see the bikes in the pictures. It's very motivating.

Haha...maybe it SHOULD be a rule for first time players...

Yeah but we've all seen your bike. We want to see his too...

[gsrick]

Y'all play find the volcano. I'll check back when there is a doable tag or the rest of you find out where that fishy smell is coming from.

[trevor]

Its been 48hrs..time for a new tag.

[tkent02]

Time for someone to get off their ass and ride.
It's an easy tag.
Can't you see Mt Baker from Victoria?

[loud et]

I have a big cast on my arm....thats my excuse
I cant even play, but I been waiting too. lol

I'll ride over to the coast and look out at the ocean. I'm sure someone will get it before one pops up. I can do some fishing while I'm there.
