[Aqualist] Fw: a little more on chevrons

[Patrick A Hesp]

Hello again folks
a little follow-up on the chevron story..

Two original articles on this stuff from the New York Times may be found 
at:
 
http://www.nytimes.com/2006/11/14/science/14WAVE.html
 
On this site you will find a small globe graphic. Open it and you will see 
locations of chevrons around the world, and examples of "chevrons" in 
Madagasgar.

and see also
 
http://www.nytimes.com/2006/11/17/science/17askscience.html

and if you want to look at a "chevron" or two, Sandra Blakeslee of the 
Science Times (in the NY Times) provided these coordinates in Madagasgar 
in repsonse to a readers enquiry:
A: On Google Earth, one good chevron is at 25 degrees 16 ’ 49.72" South 
and 44 degrees 40’ 57.42" East. Altitude 13.85 miles. 

When I visited that location I found a very nice set of parabolic dunes 
(which do of course approximate upside-down chevrons....).
cheers
