Rocky and Chip

A few weeks ago I read that perhaps there was no need to scope out the site of the Buffalo Memorial Auditorium in order to try to figure out a way smuggle a souvenir under the fence. All one had to do was ask. Imagine that. Never crossed my mind, or rather, never thought it would work. So off I went.

When I got there a woman was hauling off a small slab of marble. So before the guy could get away I politely asked for a rock. Mistake. Should have specified marble or granite. However he did bring me a rock with sparkly things in it. Probably just concrete, but having forgotten most of what little I knew of geology, I can pretend it's something unique. Plus, it's mine! A while back I had pulled a little piece of brick under the fence, figuring that small was better than nothing. Now I'm wondering if I can get a hunk of marble...


My artifacts have been personified by naming them Rocky and Chip, in part to justify keeping them in the house permanently rather than tossing them in a rock garden like some other immigrants to the neighborhood. Rocky seen here with a neighbor's outside relics:


Then again, they're from the Aud, so that makes them special. However, a display case is not in their immediate future. Finally, here is the family portrait, Rocky with Chip on his back "He's not heavy, he's my brotherrr..."

Mines, Sinkholes, and Other Fun Stuff

I heard that they want to build houses over the old gypsum mines on Roll Road. What a wonderful idea (roll eyes). I can remember, as a child, hearing the booms as they dynamited in the mines. That's what led to this:

I was roaming around the internet, reading some of my usual blogs when I wandered over to DeputyDog (I click on the links a lot). He has some wonderful photos of "7 Amazing Holes" - large mines, "glory holes", and sink holes.

One thing led to another, and I came upon stories of mine pillars collapsing and causing sinkholes, which pull buildings and roads down into the ground due to land subsidence .
"Land subsidence also occurs in areas of underground mining where removal of material causes overlying surface rock to sink or collapse. Although the locations of underground mines are often denoted on topographic and geologic maps, the potential subsidence hazard from a mine requires evaluation by a geologist."

"Similar to land subsidence due to underground mining, subsidence can also result from chemical weathering of soluble rocks (e.g. limestone, dolomite, gypsum). As groundwater flows through limestone, a chemical reaction causes the rock to dissolve, eventually forming cavities within the bedrock. As a cavity near the surface increases in size, the overlying materials can sink or collapse and create a depression on the land surface."
Tar Creek, OK is one town that has been subjected to sinkholes and threats of mine collapse for years. There are also the real toxic threats from the dust to the air and acid mine water that contaminates the water table. While it was zinc and lead mined there, gypsum , used primarily in wallboard, has its concerns also:
"In the early 1980s, landfills in British Columbia were found to be producing toxic gas and leachate from concentrations of gypsum debris that had been buried for as little as two days."
One would think that the Town of Clarence would want to shield itself from future lawsuits. There can be all kinds of studies, but that doesn't mean that the earth won't do it's unpredictable thing and shift. Then again, Amherst is off the hook for it's sinking homes.

The prevailing thought just might be that if they're insurable, and the Town's not liable, go for it. Add to the tax base and services needed, subtract from green space. Just think twice before buying a house there.
