+TechnoNut Posted September 26, 2011 Share Posted September 26, 2011 So often we hide caches near, under, on top, and jammed in and among the above. So, how should we describe them? I am thinking of something on the lines of this:- Pebble - sort of marble sized, you can get several in one hand. Stone - up to about fist size or slightly bigger, can be held in one hand. Rock - needs two hands to lug around, you are not going to carry this far. Boulder - this isn't going anywhere. Where you see it is where it stays. Any comments / additions? PT Quote Link to comment
+mr panda Posted September 26, 2011 Share Posted September 26, 2011 (edited) Sounds about right. Rock isn't a great term, since pebbles, stones and boulders are all made of rock. Geologists use the term cobble. This might help http://en.wikipedia.org/wiki/Particle_size_(grain_size) Edit - tried to fix URL, but it is still failing - easy enough to click through. also, silly me, the term 'rock' makes about as much sense as 'stone'. From the link: (the weird numbers result from the original determinations being in inches) > 256 mm = Boulder 64–256 mm = Cobble 4–64 mm = Pebble < 4 mm = Granule, Sand, Silt, Clay etc Edited September 26, 2011 by mr panda Quote Link to comment
+Skyjuggler Posted September 26, 2011 Share Posted September 26, 2011 Oh dear.... I just had an idea for a mystery Quote Link to comment
+mpilchfamily Posted September 26, 2011 Share Posted September 26, 2011 If we still consider a rock one of the categories then in my view a rock would be smaller then a stone. But wouldn't it be easier to go with a more conventional designation scheme? Small, medium, and large rocks. Quote Link to comment

+Zambesiboy Posted September 27, 2011 Share Posted September 27, 2011 From the various fun caches I have done in company of other folk this topic always features in the conversation BEFORE we find the cache! Quote Link to comment
+mr panda Posted September 27, 2011 Share Posted September 27, 2011 @Skyjuggler - A mystery huh? This gives me an idea for an earth cache... Quote Link to comment
