Blue-green algae earthcache

[tubeex1995]

I would like to make an earthcache for a lake that has Blue-green algae. But you can only find Blue-green algae 1 mount a year. Would this be ok for an earthcache? Also they have to find Blue-green algae in the lake. I will give them locotions where they could find some. So would this be accepted?

I'm having a difficult time getting my head around the idea that algea are somehow related to Geology, but I've seen write ups that describe thermophilic bacteria in hot springs and geysers, so I guess anything is possible.

As it is written above, it does not meet the EarthCache Earth science guidelines and would not be published. This is due to the major emphasis is on biology/ecology which is not covered by our definition of 'Earth science'.

"blue-green algae" can leave fossils traces called stromatolites see http://www.ucmp.berkeley.edu/bacteria/bacteriafr.html

I have a building near me which is faced with Porland Limestone that has cauliflower shaped algae fossils. I have not made an earth cache of it yet but I supposed you could claim that this blue-green algae could be fossils in a million years time so they are geology in the making!
