[meteorite-list] Is Pena Blanca Springs meteorite a hammer stone?????

[Frank Cressy]

Shawn and all,

The "swimming pool" quote is used in the abstract.  Later in the article the 
"swimming pool" is described thusly:

"Springs issue at a point where a water gap has been eroded through the ridge 
and form a creek which flows southeast.  About 400 feet below the springs, the 
creek is confined by a dam 4 feet high.  At the head of the pool the water is 
about 10 feet in depth and 20 feet wide."  


The "swimming pool" is the pool made by damming the creek, no doubt for 
irrigation and/or supplying water for livestock.  A photo of the pool is in the 
May 2000 issue of Meteorite magazine in an article about PBS.  The only man-made 
construction involved is the dam.  So I'd say "no" to it being a "hammer."  ( 
unless there was meteoritic material in the water that splashed on the farm 
truck that was driving by at the time of the fall).

Cheers,

Frank

Hello Listers,
 
I have a good question I was doing some searching around on the net today and I 
came across an article called 

 
THE PENA BLANCA SPRING METEORITE,
BREWSTER COUNTY, TEXAS
 
BY 
 
John T. Lonsdale University of Texas, Austin Texas
 
With in the article it was stated that the meteorite plunged into a swimming 
pool feed by natural spring water hence where the meteorite got its name. I have 
also read this meteorite was recovered from a pond, stock pond. Now can these 
natural spring water swimming pools be man made and if so was the one on Gages 
ranch about 9.5 miles southeast of Marathon in Brewster County, Texas man made 
as well? If thats the case wounldnt Pena Blanca Springs meteorite be a HAMMER 
STONE? 


Good indication that can suggest that this swimming pool/ pond could be man made 
is that after the pool was drained about 4 feet below normal level to recover 
some of the meteorite fragments. In order to drain a pool/pond there has to be 
some construction implemented in order to achieve that? 


Down below is some points taken from the article and also a link to the whole 
article. Please take a look and share your thoughts on what you think.

Abstract
The Pena Blanca Spring meteorite fell August 2, 1946, in the swimming pool at 
the headquarters of the Gage Ranch near Marathon in Brewster County, Texas. 
Twenty-four people were within a few hundred feet of the point of fall, and one 
person saw the meteorite in flight. Many interesting incidents were accurately 
reported.

As far as known, man has never constructed a device in which to trap
a meteorite falling to the earth. Had he done so, possibly he could not
have improved upon the swimming pool at the headquarters of the Gage
ranch about 9.5 miles southeast of Marathon in Brewster County, Texas.
This swimming pool received the Pena Blanca Spring meteorite with a
violent splash at about 1:20 p.u. on August 2, 1946. The meteorite is
named from the spring which forms the swimming pool and which is
an historic landmark in the region.

Lastly, why I brought this up is because in numerous cases I have read swimming 
pool and swimming pool means man made. But again the word can be subjective.
