Hey Debbie – we found a nice collection the next day in the picnic area on the north side of the valley just east of El Capitan. Is that were this was found too? or was it elsewhere?

I think so…

Nice find! In a weird way.

Please define the location for this obsie – we need that mapping power! I’d do it, but you can place the spot more accurately.
