AW #63: Plants and Rocks, Or Rocks and Plants

Photos courtesy Arthur Kruckeberg and Dan Poelma.

I’m hosting December’s Berry Go Round, a carnival for plant bloggers.  In my solicitation for posts I tried to encourage geo-bloggers to participate, as botany and geology often interact or are linked in some way.  Then I noticed that the Accretionary Wedge #63 geo-carnival was host-less.  I thought ... why not both?  My topic, Plants and Rocks or vice versa, was accepted making this the Bargain of the Year!  You can submit your AW contribution to the December BGR too.
To submit a post to the Accretionary Wedge, provide a link in a Comment below or tweet to @plantsandrocks.  To join the December BGR, see the solicitation post for details.
